The light-independent reactions of photosynthesis are those that A)convert glucose into energy. B)convert chlorophylls into light energy. C)convert water into hydrogen and oxygen. D)convert CO₂ into reduced molecules (sugars). E)occur only at night.

Question

Quizplus · Accepted Answer

The light-independent reactions of photosynthesis, also known as the Calvin cycle, use energy from ATP and NADPH to convert carbon dioxide (CO2) into reduced molecules, such as sugars. Option A is incorrect because glucose is not converted into energy, but rather broken down to release energy. Option B is incorrect because chlorophylls absorb light energy during the light-dependent reactions, not the light-independent reactions. Option C is incorrect because the conversion of water into hydrogen and oxygen happens during the light-dependent reactions. Option E is incorrect because the light-independent reactions can occur during both day and night.
