ATP is produced during the process of cellular respiration. Which is the order of the steps of cellular respiration?

Cellular respiration proceeds in this order: glycolysis, the Krebs cycle, and then the electron transport chain. Glycolysis breaks glucose into smaller molecules, which are further processed in the Krebs cycle; the electron transport chain uses high-energy electrons from earlier steps to produce most of the ATP. So the correct choice is C, glycolysis → Krebs cycle → electron transport chain.
