Answer the following question given this paragraph: The many steps in the process of aerobic cellular respiration can be divided into three stages. The first stage, glycolysis, produces ATP without oxygen. Because this part of the cellular respiration pathway is universal, biologists consider it the oldest segment. Note that glycogen and fats can also enter the glycolysis pathway. The second stage is the Krebs Cycle, and the third stage is the electron transport chain. It is during the third stage that chemiosmosis produces numerous ATP molecules. Q: Glycolysis, the krebs cycle, and the electron transport chain are stages in what process? Choices: - cell death - reproduction - mitosis - aerobic cellular respiration A:
(A).
aerobic cellular respiration
