How many quanta of light are needed to reduce one molecule of carbon dioxide to carbohydrate during photosynthesis?

Question

Quizplus · Accepted Answer

The reduction of one molecule of carbon dioxide to carbohydrate requires 10-12 quanta of light. This is because the process of photosynthesis involves two stages: the light-dependent reactions and the light-independent reactions (also known as the Calvin cycle). During the light-dependent reactions, light energy is used to produce ATP and NADPH, which are then used during the Calvin cycle to reduce carbon dioxide to carbohydrate. The number of quanta required for this process varies depending on the specific plant and environmental conditions, but on average, it takes 10-12 quanta to reduce one molecule of carbon dioxide.
