Question

the end product when anaerobic respiration occurs in humans is ______. a lactic acid b muscle cells c pyruvic acid

Explanation:

Anaerobic respiration in humans occurs in muscle cells when oxygen is limited. The process converts glucose into lactic acid. Pyruvic acid is an intermediate in cellular respiration (both aerobic and anaerobic), but in human anaerobic respiration, it is further converted to lactic acid. Muscle cells are the site, not the end - product.

Answer:

A. lactic acid
