The first stage of cellular respiration glycolysis is an anaerobic process. During glycolysis glucose is converted to two molecules of pyruvic acid. How is glycolysis kept functioning in cellular respiration?

Oxidation of NADH by electron transport chain ensures a continuous supply of NAD + for glycolysis.

Explanation:

To continue the process of glycolysis, cells must have a continuous supply of NAD + which is required during one of the reactions of the payoff phase of glycolysis. Two molecules of NADH are formed per glucose molecule during glycolysis. The NADH gives its electrons to the terminal electron acceptors (O2) via electron transport chain. This ensures that the process of glycolysis is continued in cells to breakdown the glucose into pyruvate.
