|
Each set produces sugars, and by working together they produce more sugars than they would produce separately.
|
|
|
Each set produces half of a sugar molecule, and later the two halves are joined together.
|
|
|
Only the light-dependent reactions produce sugars, but they depend on products of the light-independent reactions.

Only the light-independent reactions produce sugars, but they depend on products of the light-dependent reactions.

Detailed explanation-1: -What best describes the relationship between the two sets of reactions of photosynthesis, which are the light-dependent reactions and the light-independent reactions? Each set produces sugars, and by working together they produce more sugars than they would produce separately.
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: -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-4: -The site of photosynthesis is the chloroplast, which is under the surface of the leaf. The light reactions occur on the thylakoid membrane and the dark reactions occur within the stroma.
Detailed explanation-5: -Figure: The two stages of photosynthesis: Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle (light-independent reactions).
