If oxygen is available, the complete breakdown of glucose produces _ ATP molecules in proka,yotos.
Correct answer: C. 38
- A. 201
- B. 36
- C. 38
- D. 40
Explanation
A total 38 ATP molecules (2 ATP molecules from glycolysis, 2 from Krebs cycle and 34 from electron transport system) are produced per molecule of glucose oxidised in aerobic prokaryotes.

About Cellular Respiration
Cellular respiration releases energy from glucose through glycolysis, the link reaction, the Krebs cycle and the electron transport chain, producing ATP. The pathway differs in oxygen availability: aerobic respiration uses oxygen and yields more ATP, while anaerobic respiration produces much less ATP and forms lactic acid in muscles or ethanol and carbon dioxide in yeast.
