Which molecule is common to both glycolysis and the Calvin cycle?
Correct answer: D. Triose phosphate
- A. Hexose phosphate
- B. NADP
- C. Pentose phosphate
- D. Triose phosphate
Explanation
In glycolysis (respiration), triose phosphate (glyceraldehyde3-phosphate, G3P) is formed during the breakdown of glucose. In the Calvin cycle (photosynthesis), triose phosphate (G3P) is also produced as the first stable product of carbon fixation.

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.
