Thelight reactions provide ATP and NADPH to the Calvin cycle, and the Calvin cyclereturns ADP, ℗i, and NADP+ to the light reactions.
|
|
|
The light reactions provide ATP and NADPH to thecarbon fixation step of the Calvin cycle, and the Calvin cycle provides waterand electrons to the light reactions.
|
|
|
The light reactions supply the Calvin cycle withCO2 to produce sugars, and the Calvin cyclesupplies the light reactions with sugars to produce ATP.
|
|
|
The light reactions provide the Calvin cyclewith oxygen for carbon fixation, and the Calvin cycle provides the lightreactions with sugars to produce ATP.

Detailed explanation-1: -Which of the following statements best represents the relationships between the light reactions and Calvin cycle? The light reactions provide ATP and NADPH to the Calvin cycle, and the cycle returns ADP, Pi, and NADP+ to the light reactions.
Detailed explanation-2: -Which of the following statements best describes the relationship between the light-dependent and light-independent reactions of photosynthesis? The light-independent reactions release energy, and the light-dependent reactions require energy.
Detailed explanation-3: -the light dependent reactions are a brick while the calvin cycle is a brick wall.
Detailed explanation-4: -Which of the following best describes how the Calvin cycle and the light reactions of photosynthesis function together? The Calvin cycle uses ATP and NADPH generated by the light reactions to synthesize carbohydrates.
