In the dark reactions of photosynthesis,CO₂ is added to a five-carbon sugar-phosphate known as A)cyclic AMP. B)NADH. C)NAD⁺. D)RuBP. E)CAM.

Question

Quizplus · Accepted Answer

The dark reactions of photosynthesis (also called the Calvin cycle) occur in the stroma of the chloroplasts and begin with the fixation of atmospheric CO2 into a 5-carbon sugar-phosphate known as RuBP (ribulose-1,5-bisphosphate) with the help of the enzyme RuBisCO. Therefore, the correct option is D – RuBP. The other options are not involved in the dark reactions.
