Question

(03.02 MC)Human skeletal muscles can respire both aerobically and anaerobically. Which of the following best describes what happens to pyruvate under anaerobic conditions?

Answer 1

Answer:

Under anaerobic condition pyruvate is converted into lactate.

Explanation:

Human muscles use both anaerobic and aerobic respiration for the production of ATP. During the starting of intense activity, the oxygen supply is not enough to provide instant energy to the muscle, therefore, muscles use anaerobic respiration to generate ATP.

During anaerobic respiration, muscle do not use oxygen to burn glucose. During anaerobic respiration in muscles, the glucose is converted into pyruvate and then this pyruvate gets convert into lactate and this process is called lactic acid fermentation. In this process, 2 ATP are produced.
