18. how does glycolysis contribute to cellular respiration? a. it breaks down glucose into pyruvate and generates a small amount of atp. b. it produces oxygen for the electron transport chain. c. it stores glucose for later use. d. it synthesizes proteins in the cytoplasm.

Answer

Brief Explanations:

Glycolysis is the first step of cellular respiration. It occurs in the cytoplasm and breaks down glucose into two molecules of pyruvate, generating a small amount of ATP and NADH in the process. It does not produce oxygen, store glucose, or synthesize proteins.

Answer:

A. It breaks down glucose into pyruvate and generates a small amount of ATP.
