Question

Which step in cellular respiration produces the most ATP

Answer 1

The step in cellular respiration that produces the most ATP is oxidative phosphorylation, which occurs during the electron transport chain (ETC) and chemiosmosis. This process takes place in the inner mitochondrial membrane and involves the transfer of electrons through a series of protein complexes, ultimately leading to the production of ATP from ADP and inorganic phosphate. Oxidative phosphorylation can generate a significant amount of ATP, often yielding around 28-34 ATP molecules per glucose molecule, depending on cellular conditions.
