AP BIOLOGY

Detailed explanation-1: -ADP, NADP, and glucose are the end products of the C3 cycle. ADP and NADP are produced in the first stage of C3 cycle. In the second stage, glucose is produced.

Detailed explanation-2: -The reactions of the Calvin cycle add carbon (from carbon dioxide in the atmosphere) to a simple five-carbon molecule called RuBP. These reactions use chemical energy from NADPH and ATP that were produced in the light reactions. The final product of the Calvin cycle is glucose.

Detailed explanation-3: -Unlike the light reactions, which take place in the thylakoid membrane, the reactions of the Calvin cycle take place in the stroma (the inner space of chloroplasts). This illustration shows that ATP and NADPH produced in the light reactions are used in the Calvin cycle to make sugar.

Detailed explanation-4: -Products. The immediate products of one turn of the Calvin cycle are 2 glyceraldehyde-3-phosphate (G3P) molecules, 3 ADP, and 2 NADP+. (ADP and NADP+ are not really “products". They are regenerated and later used again in the light-dependent reactions).

Detailed explanation-5: -The Calvin cycle converts ATP to ADP and Pi, and it converts NADPH to NADP+. The ADP, Pi, and NADP+ can be reused as substrates in the light reactions.
