The product of the dark reaction is
Correct answer: C. G3P
- A. ATP
- B. NADPH
- C. G3P
- D. PEP
Explanation
The correct answer is glyceraldehyde 3-phosphate (G3P), which is the primary carbohydrate product of the Calvin cycle, also known as the dark reactions. During these reactions, ATP and NADPH generated in the light-dependent reactions are used to convert carbon dioxide into G3P, a three-carbon sugar. This process occurs in the stroma of chloroplasts. The other options, ATP and NADPH, are products of the light-dependent reactions, while PEP is not related to photosynthesis but rather to glycolysis.

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.
