Which of the following is not true of anaerobic metabolism?
A
Lactic acid can be a byproduct in muscle cells.
B
It involves glycolysis as a key step.

Verified step by step guidance1
Understand the concept of anaerobic metabolism: Anaerobic metabolism refers to the process of generating energy without the use of oxygen. It is typically used by cells when oxygen is scarce or during intense exercise.
Identify the key steps involved in anaerobic metabolism: The primary pathway is glycolysis, which breaks down glucose into pyruvate, producing a small amount of ATP and NADH.
Recognize the byproducts of anaerobic metabolism: In muscle cells, when oxygen is not available, pyruvate is converted into lactic acid, which can accumulate and cause muscle fatigue.
Compare ATP production in anaerobic vs. aerobic respiration: Aerobic respiration, which occurs in the presence of oxygen, produces significantly more ATP (approximately 36-38 ATP molecules per glucose molecule) compared to anaerobic respiration, which produces only about 2 ATP molecules per glucose molecule.
Evaluate the statements: Based on the understanding of anaerobic metabolism, the statement 'It produces more ATP than aerobic respiration' is not true, as anaerobic metabolism produces less ATP compared to aerobic respiration.
