Question

multiple - choice question
which process produces more energy?
aerobic cellular respiration
anaerobic cellular respiration/fermentation

Explanation:

Aerobic cellular respiration occurs in the presence of oxygen and goes through glycolysis, the Krebs cycle, and the electron transport chain. It can produce up to 38 ATP molecules from one glucose molecule. Anaerobic cellular respiration/fermentation occurs without oxygen. Fermentation (like lactic acid fermentation or alcoholic fermentation) only goes through glycolysis (producing 2 ATP from one glucose molecule) and then a fermentation step which regenerates NAD+ but produces no additional ATP. So aerobic cellular respiration is more energy - yielding.

Answer:

A. Aerobic Cellular Respiration
