Glycolysis is the breakdown of glucose into two molecules of:
Correct answer: C. Pyruvate
- A. Glycerate
- B. Lactic Acid
- C. Pyruvate
- D. Succinic Acid
Explanation
Glycolysis is the breakdown of glucose into two molecules of pyruvate. During glycolysis, which takes place in the cytoplasm of the cell, one molecule of glucose (a six-carbon sugar) is enzymatically transformed into two molecules of pyruvate (each containing three carbon atoms). This process involves a series of enzyme-catalyzed reactions and results in the production of a small amount of ATP and NADH, which are then used in subsequent stages of cellular respiration to generate more ATP.

About Bioenergetics
Cellular respiration explains how cells release energy from glucose through glycolysis, the link reaction, Krebs cycle and electron transport chain. It includes ATP production, substrate-level and oxidative phosphorylation, aerobic versus anaerobic respiration, and the roles of mitochondria, oxygen and fermentation in energy transfer.
