3-Phosphoglycerate in the presence of ATP and reduced NADP (from the light-independent stage) is reduced to:
Correct answer: D. 3 carbon compound
- A. Ribulose bisphosphate
- B. 6 carbon compound
- C. 5 carbon compound
- D. 3 carbon compound
Explanation
In the presence of ATP and reduced NADP (produced during the light-dependent reactions), 3-phosphoglycerate (3-PGA) is reduced to glyceraldehyde-3-phosphate (G3P) during the light-independent reactions of photosynthesis, also known as the Calvin Cycle.

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.
