Question

what happens during anaerobic cellular respiration?

Explanation:

Anaerobic cellular respiration occurs without oxygen. Glucose is partially broken - down. In glycolysis, glucose is split into pyruvate and a small amount of ATP is produced. Then, pyruvate is converted into either lactic acid (in lactic - acid fermentation) or ethanol and carbon dioxide (in alcoholic fermentation) to regenerate NAD+ for glycolysis to continue.

Answer:

Glucose is partially broken down starting with glycolysis, and then pyruvate is converted into either lactic acid or ethanol and carbon dioxide to regenerate NAD+ for glycolysis to keep going, with a small amount of ATP produced.
