What is the relationship between the light-dependent and light-independent reactions of photosynthesis?

Question

Responses

The light-dependent reactions produce simple carbon products that are converted to sugars, lipids, and proteins in the light-independent reactions.
The light-dependent reactions produce simple carbon products that are converted to sugars, lipids, and proteins in the light-independent reactions.

The light-independent reactions produce simple carbon products that are converted to sugars, lipids, and proteins in the light-independent reactions.
The light-independent reactions produce simple carbon products that are converted to sugars, lipids, and proteins in the light-independent reactions.

The light-independent reactions provide the ATP and NADPH necessary for the light-dependent reactions, which produce carbon compounds such as glucose.
The light-independent reactions provide the ATP and NADPH necessary for the light-dependent reactions, which produce carbon compounds such as glucose.

Answer 1

The correct statement regarding the relationship between the light-dependent and light-independent reactions of photosynthesis is:

The light-dependent reactions provide the ATP and NADPH necessary for the light-independent reactions, which produce carbon compounds such as glucose.

In more detail, the light-dependent reactions, which occur in the thylakoid membranes of the chloroplasts, use sunlight to generate ATP and NADPH while splitting water molecules and releasing oxygen. These products (ATP and NADPH) are then utilized in the light-independent reactions (Calvin cycle) to convert carbon dioxide into glucose and other organic compounds.
