Question

question 3 (1 point) which stage of photosynthesis, if any, can function in the dark? a) stage 1 (the light reactions) b) stage 2 (the calvin cycle) c) both stage 1 (the light reactions) and stage 2 (the calvin cycle) d) neither stage 1 (the light reactions) nor stage 2 (the calvin cycle)

Explanation:

Photosynthesis has two - stage. The light - reactions (Stage 1) require light energy to occur as they involve the absorption of light by chlorophyll and generation of ATP and NADPH. The Calvin cycle (Stage 2) is a series of chemical reactions that can occur in the dark as long as it has the ATP and NADPH generated from the light - reactions.

Answer:

B. Stage 2 (the Calvin cycle)
