Question

Does CO2 is released in anaerobic respiration and in human does the level of carbondioxide became high

Answer 1

Anaerobic respiration is the breakdown of glucose in the absence of oxygen. ... If oxygen is absent, then pyruvic acid converts into lactic acid, carbon dioxide, and water. This is unlike aerobic respiration, in which pyruvic acid converts into Acetyl CoA, which further goes into the mitochondria.
