Which Process Occurs During Photosynthesis

Question

Which process occurs during photosynthesis?
A) The light reactions produce NADP from sunlight energy.
B) Carbon dioxide reacts with 5-carbon molecules during the Calvin cycle.
C) ATP is released at the end of the Calvin cycle.
D) Water captures the electrons released from excited chlorophyll pigments.

Accepted Answer

During photosynthesis, carbon dioxide reacts with 5-carbon molecules (RuBP) during the Calvin cycle, which results in the production of glucose. The light reactions that occur in the thylakoid membrane produce ATP and NADPH from sunlight energy, and water is split to capture electrons and produce oxygen as a byproduct. However, the production of NADP from sunlight energy is not a process that occurs during photosynthesis. ATP is produced during the light reactions, but it is not released at the end of the Calvin cycle.
