The Calvin cycle makes direct use of ________ to make ________.
A)light energy and CO₂...sugar
B)CO₂,ATP,and NADPH...sugar and O₂
C)light energy,CO₂,and water...sugar and O₂
D)CO₂,ATP,and NADPH...sugar

Question

Quizplus · Accepted Answer

The Calvin cycle is a series of enzyme-catalyzed reactions that take place in the stroma of chloroplasts and use the energy from ATP and NADPH, generated during the light-dependent reactions, to convert carbon dioxide into glucose or other sugars. Therefore, the Calvin cycle makes direct use of CO₂, ATP, and NADPH to make sugar (glucose). Choice A is incorrect because the Calvin cycle does not use light energy directly to make sugar. Choice B is incorrect because it suggests that O₂ is also made during the Calvin cycle, which is not true. Choice C is incorrect because water is not used as a direct input for the Calvin cycle.
