The end product of Glycolysis is:
Correct answer: C. Pyruvate
- A. Glucose-6-phosphate
- B. Fructose-6-phosphate
- C. Pyruvate
- D. 3-Phosphoglycerate
- E. Phosphoglyceraldehyde
Explanation
The end product of glycolysis is pyruvate. During glycolysis, one molecule of glucose is broken down into two molecules of pyruvate, yielding a net gain of two molecules of ATP and two molecules of NADH. Pyruvate can then enter the mitochondria to be further processed in the citric acid cycle if oxygen is present, or it can undergo fermentation under anaerobic conditions. The incorrect options listed are intermediates in the glycolytic pathway, not final products.

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.
