Question

Why does anaerobic respiration produce less energy compared to aerobic respiration? *Please answer in simple words*

Answer 1

• Without oxygen, organisms can split glucose into just 2 molecules of pyruvate. This releases only enough energy to make two ATP molecules.
• With oxygen, organisms can break down glucose all the way to carbon dioxide. This releases enough energy to produce up to 38 ATP molecules. Thus, aerobic respiration releases much more energy than anaerobic respiration.

Answer 2

Answer:

because anaerobic respiration uses the oxidizing agent that is less affective than oxygen
