what is the primary function of light reactions
A) The light reactions provide ATP and NADPH to the Calvin cycle, and the cycle returns ADP, Pi, and NADPâº to the light reactions. B) The light reactions provide ATP and NADPH to the carbon fixation step of the Calvin cycle, and the cycle provides water and electrons to the light reactions. C) The light reactions supply the Calvin cycle with COâ to produce sugars, and the Calvin cycle supplies the light reactions with sugars to produce ATP.
