What is one role of ATP in the light-independent reaction of photosynthesis?

Answer
A
ATP supplies the energy to split water molecules.
B
ATP produces CO sub 2 and cap o sub 2 molecules.
C
ATP is produced when water molecules are split and chlorophyll electrons are excited.
D
ATP supplies the energy to produce glucose and other carbohydrates.

Explanation

The light-independent reactions use energy from ATP to help build carbohydrates from carbon dioxide. ATP is made during the light-dependent reactions, where light excites chlorophyll electrons; it does not split water or produce carbon dioxide and oxygen. Therefore, the correct choice is D, ATP supplies the energy to produce glucose and other carbohydrates.
