Correct answer: B. Mitochondria
- A. Cytosol
- B. Mitochondria
- C. Nucleus
- D. All of these
Explanation
Mitochondria is the only place where ATP can be synthesized as the compartmentalization within the mitochondria provides an efficient and regulated environment for ATP synthesis and efficient energy production.

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.
