A aldo sugar that is intermediate between respiration and photosynthesis:
Correct answer: C. Glyceraldehyde 3-phosphate
- A. Glucose
- B. Dihydroxyacetone
- C. Glyceraldehyde 3-phosphate
- D. Fructose
Explanation
The aldose sugar that is an intermediate between respiration and photosynthesis is glyceraldehyde-3-phosphate (G3P). G3P is a key intermediate in both the glycolysis pathway and the Calvin cycle of photosynthesis. In glycolysis, G3P is produced during the conversion of glucose to pyruvate, while in the Calvin cycle, it is produced during the fixation of carbon dioxide.

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.
