Question

Quizplus · Accepted Answer

The light reactions of photosynthesis produce ATP and NADPH, which are both used as energy and reducing power sources to power the Calvin cycle. Choice A is incorrect because while light energy is used in the light reactions, it is not directly supplied to the Calvin cycle. Choice B is incorrect because CO2 is not produced in the light reactions, and while ATP is produced, it is not directly supplied to the Calvin cycle along with CO2. Choice C is incorrect because while H2O and NADPH are used in the light reactions, they are not supplied to the Calvin cycle as products. Choice E is incorrect because while sugar is produced in the Calvin cycle, it is not supplied back to the Calvin cycle as a reactant.
