Which of the following statements about the Calvin cycle is correct?

Question

Quizplus · Accepted Answer

The Calvin cycle involves the fixation of carbon dioxide into organic molecules through a series of enzymatic reactions. One of the key steps is the reduction of CO2 to form glucose, which involves the addition of hydrogen atoms derived from NADPH. Therefore, choice A is the correct statement as it describes the reduction of CO2 to form CH2O (which can be further modified to form glucose). Choice B is incorrect as it describes a different compound not involved in the Calvin cycle. Choice C is incorrect as it describes a compound that does not exist. Choice D is incorrect as CO2 is not used to form ATP in the Calvin cycle, but instead is used to form energy-rich molecules like glucose.
