Question

Anaerobic respiration occurs when?

Answer 1

Anaerobic respiration occurs when there is no oxygen present. The steps are glycolysis, alcohol or lactic acid fermentation instead of aerobic respiration, which steps are glycolysis, Kreb's cycle, and electron transport chain. Hope this helps! :)

Answer 2

Anaerobic respiration takes place in the fluid portion of the cytoplasm of cells, away from the mitochondria or any other organelles. It begins with glycolysis, which breaks apart glucose and generates energy and a compound known as pyruvate, and also includes fermentation, which breaks down the pyruvate for more energy.
