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 describing 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 capture solar energy and convert it into chemical energy in the form of ATP and NADPH. These products are then used in the light-independent reactions (also known as the Calvin cycle) to convert carbon dioxide into glucose and other organic molecules.
