Question

The process of aerobic and anaerobic respiration, as well as fermentation, all begin with

Answer 1

Fermentation, anaerobic respiration, and aerobic respiration all begin with glycolysis.

Step-by-step explanation:

Fermentation, anaerobic respiration, and aerobic respiration all begin with glycolysis. Glycolysis is the first stage of cellular respiration where glucose is broken down into pyruvate. In fermentation, pyruvate is used directly or indirectly to accept electrons from NADH. In anaerobic respiration, glycolysis is followed by other steps, including the citric acid cycle, where pyruvate enters to produce more ATP.
