The complete breakdown of glucose molecules takes place in which of the following?
Correct answer: C. Aerobic respiration
- A. Alcoholic fermentation
- B. Lactic acid fermentation
- C. Aerobic respiration
- D. None of these options are correct
Explanation
Aerobic respiration is the process where cells use oxygen to convert glucose into energy (ATP), releasing carbon dioxide and water as byproducts. This highly efficient process occurs in the mitochondria of most living organisms, including plants and animals, to power essential functions like muscle contraction, growth, and body heat.

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.
