Sveta_85 [38]

Answer: c. 2 pyruvate molecules

Explanation:

Glycolysis is the first step it the cell respiration cycle. It turns one molecule of glucose into two molecules of pyruvate by a series of reactions catalyzed by different enzymes.

It starts by using 2 ATP to turn glucose into fructose-1,6-bisphosphate, which then divides in two and releases 4 ATP when it turns into two pyruvate molecules.

Thus glycolysis consumes 2 ATP and releases 4 ATP (giving a net gain of 2 ATP) and 2 pyruvate molecules.
