GarryVolchara [31]

Answer:

C) The Calvin cycle requires ATP and NADPH, which require sunlight to be produced

Explanation:

The light-dependent phase of photosynthesis includes the photolysis of water molecules. The released electrons are passed to PSII to PSI via electron carriers and finally to NADP+ to reduce it into NADPH.

Transfer of electrons via electron carriers also generates the proton concentration gradient which in turn drives ATP synthesis. ATP and NADPH formed during light reactions are used in the Calvin cycle as an energy source and electron donor respectively.

Hence, to continue, the Calvin cycle requires the synthesis of ATP and NADPH in the presence of light.
