The energy yield as a result of the total oxidation of one glucose molecule during cellular respiration is to convert:
Correct answer: A. 38 molecules of ATP
- A. 38 molecules of ATP
- B. 2 molecules of ATP
- C. 4 molecules of ATP
- D. 18 molecules of ATP
Explanation
The total oxidation of one glucose molecule during cellular respiration produces about 38 molecules of ATP. This occurs through a series of stages, including glycolysis, the Krebs cycle, and the electron transport chain. The energy released in this process is used by cells for essential activities such as growth, repair, and maintenance.

About Bioenergetics
Cellular respiration explains how cells release energy from glucose through glycolysis, the link reaction, Krebs cycle and electron transport chain. It includes ATP production, substrate-level and oxidative phosphorylation, aerobic versus anaerobic respiration, and the roles of mitochondria, oxygen and fermentation in energy transfer.
