[Campbell Biology P.260] What does the light reactions supply to the Calvin cycle? | Practice Question

What does the light reactions supply to the Calvin cycle?

  • A: light energy.
  • B: CO2 and ATP.
  • C: H2O and NADPH.
  • D: ATP and NADPH.

Explanation

The light reactions convert light energy into chemical energy in the form of ATP and NADPH. These two molecules then provide the necessary energy and reducing power for the Calvin cycle to fix carbon dioxide and produce sugars.
