Question

question
when is most of the atp in cellular respiration produced?
answer
during glycolysis
during the last steps, when the electron transport chain generates a proton gradient for atp synthase to use
it is produced in equal amounts at all stages of cellular respiration
during pyruvate oxidation
in the citric acid cycle
i dont know yet

Explanation:

Cellular respiration has three main stages: glycolysis, the citric acid cycle (Krebs cycle), and oxidative phosphorylation (which includes the electron transport chain and chemiosmosis). Glycolysis produces a small amount of ATP (net 2 ATP per glucose molecule). Pyruvate oxidation does not directly produce ATP. The citric acid cycle also produces a relatively small amount of ATP (1 ATP per turn, and 2 turns per glucose, so 2 ATP). The majority of ATP is produced during oxidative phosphorylation. The electron transport chain generates a proton gradient, and ATP synthase uses this gradient to produce ATP. This process (chemiosmosis) can produce about 26 - 28 ATP per glucose molecule.

Answer:

During the last steps, when the electron transport chain generates a proton gradient for ATP synthase to use.
