Which Paths Produce the Most ATP per Glucose Molecule

Its important to know how many ATP, or adenosine triphosphate, are produced per glucose molecule by various metabolic pathways, such as the Krebs cycle, fermentation, glycolysis, electron transport, and chemiosmosis. Take a look at how many net ATP are produced per pathway  and which yields the most ATP per glucose. Here is the breakdown of net ATP production: Glycolysis: 2 ATPKrebs Cycle: 2 ATPOxidative Phosphorylation (Electron Transport Chain/Chemiosmosis): 28 ATPFermentation: 2 ATP So, oxidative phosphorylation is the metabolic cycle that produces the most net ATP per glucose molecule.

Essay on “The Roles of a Single Mother”

Essay on â€Å"The Roles of a Single Mother† Mothers are arguably some of the best multi-taskers in the world today. The sheer amount of responsibilities they need to juggle makes them a combination of nurturer, caregiver, teacher, nurse, cheerleader, disciplinarian and more. I would know—Im a mother, myself. If there is something even more challenging than being a mother, though, it is being a single mother with no parents to help you out. My situation is a little different from other single mothers, however. Aside from the aforementioned roles, I also took on the additional roles of full-time student and part-time worker. Thankfully, Ive learned enough from the University of Hard Knocks with respect to balancing school and family life. Most of my time is devoted to caring for my children. My studies take second place, with work coming in third and the remaining fraction of my time left for the rest. Unfortunately, juggling all of the things Ive mentioned above does not necessarily translate into calmness and ease all the time. In fact, it often leads to role strain. There are times when I actually wish I had help in the form of a helpmate—someone who could look after the kids while I sought that much-needed break. My children are precious to me, yet there are admittedly days when they seem semi-precious. This most often happens when their needs prevent me from keeping up with my homework. Sometimes, my assignments have to take a backseat to more pressing needs like feeding them, cleaning them or helping them with their own assignments. My social life is almost non-existent as a result of this (Szakaly, Role Strain in Caregiving). The good news is that my part-time job doesnt really feel like work. In fact, it feels more like an interesting diversion—a chance to go out and meet new people and help someone out. The benefits work both ways: the people I reach out get their needs met and I get the chance to forget my own problems for a while (Howe, Meeting the Challenge of Being a Single Mom). It is also a great opportunity for me to connect with someone other than my kids and it helps me grow in a fun way. Then there are the rough days when the frustration sets in. During these dark times, I continuously remind myself of my reason for doing this precarious balancing act: to provide a better life for my kids. When they are sleeping, I take the time to ground myself, to pray and to ask God for the strength to do what is right (Szakaly, Role Strain in Caregiving). At first glance, it would seem as if I am the sum of these statuses and nothing more. Most people look at me and see a struggling mother, a part-time worker and a student, and rightly so, for these things are part of my current life. However, I am working hard to be more than just them. I know that God put me on Earth for a reason. Part of my lifes meaning comes from discovering that reason and living it out to the best of my ability. One day, I will not only live out my potential—I will transcend it as well. In closing, I see my status as a single mother as a supreme challenge. It tests my conviction and my courage on a daily basis to the point where I question and doubt myself. Nevertheless, all it takes is a prayer and one look at my sleeping children to get me back on track. As God has showed me time and time again, it is in dying to myself daily and in trusting Him completely that I discover the person that I really am and the life that I am truly meant to live.

Is Time Travel Possible - 2057 Words

Is Time Travel Possible? Introduction Time Travel is a concept that has fascinated me and many others throughout time, using the question of ‘Is Time Travel Possible?’ also asked by many others in the world today. I will research what time travel is, how it can be done, and if and when it could be possible to develop my understanding of the concept then state my views and opinions on time travel. What is Time travel? Time travel is a concept of movement between different points in time usually with a time machine. Time travel is recognised in fiction and philosophy but has limited support by theoretical physics. The concept of time travel is popular in many science fiction novels but one in particular brought time travel to the peak of public imagination, written in 1895 by H.G Wells, this novel is called The Time Machine. More recently, with advancing technology and understanding of the universe, time travel has been explored further by writers, philosophers and physicists. Einstein s Theory Of General Relativity and its suggested ways of time travel The strongest Theory of time travel is Einstein’s theory of General Relativity. In 1905 Albert Einstein determined that the laws of physics are the same for all non accelerating observers, and that the speed of light in a vacuum was independent of the motion of all the observers. This was the theory of special relativity. Einstein then spent ten years trying to include acceleration in the theory and that became theShow MoreRelatedWhat If Time Travel Is Possible?959 Words   |  4 PagesWhat if Time Travel was Possible?

The Holy Trinity by Masaccio Essay Example For Students

The Holy Trinity by Masaccio Essay The Holy Trinity by Masaccio was done approximately 1428. It is a superb example of Masaccios use of space and perspective. It consists of two levels of unequal height. Christ is represented on the top half, in a coffered, barrel-vaulted chapel. On one side of him is the Virgin Mary, and on the other, St. John. Christ himself is supported by God the Father, and the Dove of the Holy Spirit rests on Christs halo. In front of the pilasters that enframe the chapel kneel the donors husband and wife. Underneath the altar a masonry insert in the painted composition is a tomb. Inside the tomb is a skeleton, which may represent Adam. The vanishing point is at the center of the masonry altar, because this is the eye level of the spectator, who looks up at the Trinity and down at the tomb. The vanishing point, five feet above the floor level, pulls both views together. By doing this, an illusion of an actual structure is created. The interior volume of this structure is an tension of the space that the person looking at the work is standing in. The adjustment of the spectator to the pictured space is one of the first steps in the development of illusionistic painting. Illusionistic painting fascinated many artists of the Renaissance and Baroque periods. The proportions in this painting are so numerically exact that one can actually calculate the numerical dimensions of the chapel in the background. The span of the painted vault is seven feet, and the depth is nine feet. Thus, he achieves not only successful illusion, but a rational, metrical coherence that, by maintaining the mathematical proportions of the surface design, is responsible for the unity and harmony of this monumental composition. Two principal interests are summed up by The Holy Trinity: Realism based on observation, and the application of mathematics to pictorial organization. All of the figures are fully clothed, except for that of Christ himself. He is, however, wearing a robe around his waist. The figure is real; it is a good example of a human body. The rest of the figures, who are clothed, are wearing robes. The drapery contains heavy folds and creases, which increases the effect of shadows. The human form in its entirety is not seen under the drapery; only a vague representation of it is seen. It is not at all like the wet-drapery of Classical antiquity. Massacio places the forms symmetrically in the composition. Each has its own weight and mass, unlike earlier Renaissance works. The fresco is calm, and creates a sad mood. The mood is furthered by the darkness of the work, and the heavy shadows cast. Grunewalds The Isenheim Altarpiece is an oil painting on wood, completed in 1515. The altar is composed of a carved wooden shrine with two pairs of movable panels, one directly in back of the other. The outermost scene is the Crucifixion; on the inside there are two others. On the two sides, two saints are represented St. Sebastian on the left, and St. Anthony on the right. Together, these saints established the theme of disease and healing that is reinforced by the inner paintings. On the bottom of the panel, when opened, it appears that Christs legs were amputated; possibly an allusion to ergotism, a disease treated in the hospital where the altarpiece was kept. An image of the terrible suffering of Christ is in the middle. The suffering body hangs against the dark background, which falls all the way to the earth. The flesh is discolored by decomposition and is studded with the thorns of the lash. His blackening feet twist in agony, as do his arms. His head is to one side, and his fingers appear as crooked spikes. .ua62301a507b2e36a2f269de552cfb8f4 , .ua62301a507b2e36a2f269de552cfb8f4 .postImageUrl , .ua62301a507b2e36a2f269de552cfb8f4 .centered-text-area { min-height: 80px; position: relative; } .ua62301a507b2e36a2f269de552cfb8f4 , .ua62301a507b2e36a2f269de552cfb8f4:hover , .ua62301a507b2e36a2f269de552cfb8f4:visited , .ua62301a507b2e36a2f269de552cfb8f4:active { border:0!important; } .ua62301a507b2e36a2f269de552cfb8f4 .clearfix:after { content: ""; display: table; clear: both; } .ua62301a507b2e36a2f269de552cfb8f4 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .ua62301a507b2e36a2f269de552cfb8f4:active , .ua62301a507b2e36a2f269de552cfb8f4:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .ua62301a507b2e36a2f269de552cfb8f4 .centered-text-area { width: 100%; position: relative ; } .ua62301a507b2e36a2f269de552cfb8f4 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .ua62301a507b2e36a2f269de552cfb8f4 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .ua62301a507b2e36a2f269de552cfb8f4 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .ua62301a507b2e36a2f269de552cfb8f4:hover .ctaButton { background-color: #34495E!important; } .ua62301a507b2e36a2f269de552cfb8f4 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .ua62301a507b2e36a2f269de552cfb8f4 .ua62301a507b2e36a2f269de552cfb8f4-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .ua62301a507b2e36a2f269de552cfb8f4:after { content: ""; display: block; clear: both; } READ: Landscape painting with Thomas Cole EssayThe shuddering tautness of Christs nerves is expressed through the positions of his fingers. Up to this point, no other artist has ever produced such an image of pain. The sharp, angular shapes of anguish appear in the figures of the swooning Virgin and St. John, and in the shrill delirium of the Magdalene. On the other side, John the Baptist, a gaunt form, points a finger at the body of the dead Christ. Even though death and suffering are dominant in the altarpiece, there are symbols of hope: The river behind St. John, which represents baptism, and the wine-red sky which symbolizes the blood of Christ. Through these bols, a hope of salvation is offered to the viewer. The use of space is ambiguous in some places: All of the forms are at the same general depth in the painting. However, none of the forms are tangled, or intertwining. Therefore, the space is not badly used. Once again, all of the forms except for that of Christ are fully clothed. Christ is again wearing a small robe around his waist. The other forms are depicted superbly. Their bodies are not lost behind the drapery which they wear, yet they are not seen exactly either. The folds are more delicate, which create a calmer mood. Christs description was already given. The forms are three dimensional, and also have weight. They clearly take up space, and where they are is clearly defined. As in The Holy Trinity, the composition is generally symmetrical, centered around the body of Christ. It is a frightful composition, because of the events taking place. Expression is shown on all of the figures, who grieve Christs death. Overall, the two works are very similar. Masaccio, however, was more interested in the mathematical aspects of painting than Grunewald. Both works are superb, and have their own distinct qualities.
