Verified step by step guidance1
Understand that cellular respiration is a process that cells use to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products.
Recognize that aerobic cellular respiration consists of three main stages: Glycolysis, the Citric Acid Cycle (Krebs Cycle), and Oxidative Phosphorylation.
Identify that the majority of ATP is produced during the Oxidative Phosphorylation stage, which occurs in the mitochondria.
Note that Oxidative Phosphorylation is the final stage of aerobic cellular respiration, where the electron transport chain and chemiosmosis occur.
Conclude that the largest amount of ATP is made by Oxidative Phosphorylation in the final steps of aerobic cellular respiration.
