The later steps release much more ATP. Summary of Cellular Respiration Cellular respiration can be an anaerobic or aerobic respiration, depending on whether or not oxygen is present. In cellular respiration, the electron transport stage is when most adenosine triphosphate (ATP) is produced. Most of the ATP produced by aerobic cellular respiration is made by oxidative phosphorylation. Carbon dioxide is considered a waste product of cellular respiration. Uses of Cellular Respiration Plants and animals both use cellular respiration to perform life functions on a daily basis. Oxygen is needed to help the process of turning glucose into ATP. which stage of cellular respiration produces the most molecules of ATP per molecule of glucose? During this phase, a molecule of glucose is broken down into two molecules of pyruvate. Start studying Cellular Respiration 2.06 FLVS (80%). Question: What phase of cell respiration produces the most ATP? However, plants have a reverse cycle of cellular respiration, which produces oxygen as an end product. Electron transport chain The electron transport chain is the last stage of the respiration pathway and is the stage that produces the most ATP molecules. As you know, plants get their food by a process called photosynthesis. In this stage, energy from NADH and FADH 2 , which result from the Krebs cycle, is transferred to ATP. Acetyl-CoA's entrance into the citric acid cycle is the beginning of stage III of catabolism. This phase is carried out in several steps. ETS forms the maximum no of ATP Other cycles forms NADH and less ATP , but these NADH ultimately forms ATP in ETS Electron transport is the third stage in cellular respiration. This delicate balance makes animals and plants dependent on each other for survival. This stage of cellular respiration is highly dependent on the presence of oxygen. In aerobic production, ATP is produced by mitochondria in addition to glycolysis. These two molecules then move on to the second phase of the cellular respiration process. After pyruvic acid is produced, the Krebs cycle begins. Does Hermione die in Harry Potter and the cursed child? Why is ATP synthase important in cellular respiration? The second phase, or the Krebs cycle, begins when the pyruvate molecules enter the mitochondrion. Oxidative phosphorylation is the step of cellular respiration that produces the most ATP. The end result is the production of pyruvic acid. During anaerobic respiration, ATP is synthesized through glycolysis. The reactions of glycolysis take place in the cytoplasm of the cell and include several enzymes which act to modify the glucose molecule. What is the net gain of ATP in cellular respiration? The first phase of cellular respiration is glycolysis, which involves splitting glucose. Anaerobic respiration first appeared when the earliest life forms arose on Earth and did not have access to oxygen. How many ATP are made in the electron transport part of cellular respiration?
