what stage of cellular respiration produces the most atp

How much ATP is produced in all three stages combined? 10 NADH is of 2 molecules from Glycolysis, 8 molecules from the Krebs cycle. Each of these stages produces 2 ATPs from substrate level phosphorylation. In the presence of oxygen, glycolysis is the first stage of cellular respiration. Glycolysis produces two ATP molecules, and the Krebs cycle produces two more. The protein ATP synthase uses the energy produced by the electron transport chain for the phosphorylation (adding a phosphate group to a molecule) of ADP to ATP. -Cellular respiration uses energy in glucose to make ATP. what stage of cellular respiration produces the most atp. Consequently, which of the three stages of cellular respiration produces the most ATP? The NADH and FADH2 formed during redox reactions of glycolysis and Kreb's cycle are oxidized through the electron transport chain and drive the synthesis of up to 32 ATPs. Answer to: What phase of cell respiration produces the most ATP? We can describe each stage's ATP production. Electron transport begins with several molecules of NADH and FADH 2 from the Krebs cycle and transfers their energy into as many as 34 more ATP molecules. This is the overall equation: C6H12O6(glucose) + 6O2 → 6CO2 + 6H2O + ≈38 ATP Cellular respiration produces 36 total ATP per molecule of glucose across three stages. It's 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. Glycolysis produces 2 ATP molecules, and the Krebs cycle produces 2 more. The electron transport chain is the last stage of the respiration pathway. ATP Synthase is a type of an enzyme that makes ATP continuously for the reactions and cellular respiration. Glycolysis can occur with or without oxygen. Aerobic (“oxygen-using”) respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport. a. The stage of cellular respiration which yields the most ATP is the electron transport chain. In the absence of oxygen, glycolysis allows cells to make small amounts of ATP through a process of fermentation. Glycolysis and Kreb's cycle are first and second stages of cellular respiration respectively. Cellular Respiration gives both plant and animal cells the useable energy, aka ATP, that they need to do stuff. Most ATP generation occurs during the electron transport chain and oxidative phosphorylation stage of cellular respiration. It is the stage that produces the most ATP molecules. 2FADH2 is accepted from the Krebs cycle. ←Full Sourdough Class May 8th 2021 in Bethania Qld.
