Question

Which of the following does not happen during the Calvin cycle?

• A. Regeneration of the $C{O}_2$ acceptor
• B. Oxidation of NADPH
• C. Release of oxygen
• D. Consumption of ATP

Answer 1

Answer: (C)

Release of oxygen

Calvin cycle is the process which occurs in the chloroplast during photosynthesis. There is a regeneration of the RUBP acceptor which can be used for the next cycle. There is oxidation of the NADPH to form NADP${}^{+}$ during the reduction step. There is consumption of the carbon dioxide and ATP to form the molecule of glucose.

Thus, the correct answer is option C.
