Question

what is one role of atp in the light - independent reaction of photosynthesis?
atp supplies the energy to produce glucose and other carbohydrates.
atp is produced when water molecules are split and chlorophyll electrons are excited.
atp supplies the energy to split water molecules.
atp produces co₂ and o₂ molecules.

Explanation:

In the light - independent reactions (Calvin cycle) of photosynthesis, ATP supplies energy for the synthesis of glucose and other carbohydrates from carbon dioxide. Splitting of water and excitation of chlorophyll electrons occur in light - dependent reactions. ATP is not used to split water, and it does not produce $CO_2$ and $O_2$ molecules.

Answer:

ATP supplies the energy to produce glucose and other carbohydrates.
