Glycolysis is one of four steps that completes the process of Cellular Respiration (Erster 14). It` is a process that breaks down glucose into pyruvate and ATP (Erster 15). Glycolysis itself takes ten chemical reactions to complete its process, and within that are two mechanisms are used in order to create ATP. During substrate-level phosphorylation, a substrate molecule gives up a phosphate, which is moved by an enzyme to ADP, and then it turns into ATP. This happens not only in glycolysis, but also in the Krebs cycle and in turn creates the 10% of ATP (Erster 13). Oxidative phosphorylation is the other mechanism that makes up for the other 90% of the ATP produced, and that is done in the mitochondria where ATP synthase speeds up the making of ATP by using the energy from electron carriers that were oxidized (Erster 13, Campbell & Reece, 167). After the process of Glycolysis is completed, the net products are two molecules of pyruvate, two of water, two of ATP, two of NADH (electron carrier) and two H+ ions. …show more content…
Choice B is incorrect because substrate-level phosphorylation is not the only mechanism to create ATP. Oxidative phosphorylation creates majority of the ATP (as stated above) and substrate-level phosphorylation makes up for the small percentage of ATP that the other mechanism did not create. Therefore it cannot account for 100% of the ATP

Similarities Between Photosynthesis And Cellular Respiration

Photosynthesis and Cellular Respiration Photosynthesis and Cellular Respiration are two roles that play in everyday life. Photosynthesis and Cellular Respiration are alike, but also different. They’re alike because both processes obtain the needed substances as well as producing them. Both Photosynthesis and Cellular Respiration create very similar substances. For example, water, glucose, oxygen and carbon dioxide. However, both processes do it in distinct ways. Photosynthesis and Cellular Respiration are also…

Cellular Respiration Research Paper

Cellular respiration can be defined as the set of reactions that take place inside a cell to convert energy from nutrients into the high-energy molecule adenosine triphosphate (ATP), this energy is used to fuel all the activities of the cell, with the release of waste products (Biology Online Dictionary , 2010). Energy can be defined as the ability to do work; cellular respiration provides energy to do this work in living organisms. Cellular respiration is important as it allows all organisms to…

Essay about Glycolysis: Cellular Respiration and Atp Synthase

Chapter 9 Assignment Glycolysis is the process where glucose made during photosynthesis is broken down. Glycolysis occurs in the cytosol and does not need oxygen to work. The process of glycolysis requires 2 ATP and glucose and uses it to produce 2 pyruvates, 2 additional ATP, 2 NADH, and carbon dioxide as well. Pyruvate Oxidation occurs in the inner membrane of mitochondria. Pyruvate Oxidation does not need oxygen to operate as well. The process of Pyruvate Oxidation needs pyruvates (produced…

Biology - Cellular Respiration Essay

1 Introduction to cellular respiration and fermentation: Aerobic Cellular Respiration: is the process that extracts energy from food in the presence of oxygen. The energy is used to synthesize ATP from ADP and Pi. The ATP molecules are then used to supply energy directly to the cell for their energy-demanding activities. The equation bellow shows how glucose and oxygen are used to release ATP: C6H12O6 + 6O2  6CO2 + 6H2O ∆G = -2870 KJ/mol Aerobic cellular respiration can be divided into…

Cellular Respiration Research Paper

Cellular Respiration & Photosynthesis Cellular Respiration As living things we all need energy to function and we get it from all food we eat. Cells get the energy from stored food through cellular respiration, an easy way for them to get ATP. ATP is an energy molecule. There are three phases of cellular respiration: glycolysis, the citric acid cycle, and electron transport. Phases #1: Glycolysis Glycolysis is the phase where sugar (glucose) is split into two molecule of a three carbon…

Explain why a simple exergonic free energy diagram would not be sufficient for cellular respiration with the following equation: C6H12O6 + 6O2 → 6CO2 +6H2O + 36 ATP That shows the overall process of oxidation of glucose to release energy. Not really sure of the question/answer. In terms of the cell respiration intermediary molecules, explain where the all the carbon atoms (C) in CO2 comes from when you exhale. Be specific. CO2 which usually takes glucose and oxygen which produces carbon dioxide…

Define the terms cellular respirations, dehydrogenations, oxidations and reductions Cellular Respiration: Cellular respiration is the process by which the chemical energy of "food" molecules is released and partially captured in the form of ATP. Dehydrogenations: Dehydrogenation is a chemical reaction that involves the removal of hydrogen from a molecule. It is the reverse process of hydrogenation. Oxidations: A chemical reaction in which there…
