Complete breakdown of glucose molecule takes place in which of the following?

Correct answer: C. Aerobic respiration

  • A. Alcoholic fermentation
  • B. Lactic acid fermentation
  • C. Aerobic respiration
  • D. All of these

Explanation

Aerobic respiration completely oxidizes glucose to carbon dioxide and water through glycolysis, the Krebs cycle and the electron transport chain. The likely mistake is choosing alcoholic or lactic acid fermentation because both begin with glucose breakdown, but fermentation stops before complete oxidation and leaves energy-rich end products.
