Which one are intermediates in respiration and photosynthesis both?
Correct answer: B. Glyceraldehyde and dihydroxyacetone
- A. Ribose and heptolose
- B. Glyceraldehyde and dihydroxyacetone
- C. Glucose and galactose
- D. Fructose and ribulose
Explanation
Glyceraldehyde and dihydroxyacetone are intermediates in both glycolysis (respiration) and the Calvin cycle (photosynthesis).

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.
