Question

what is the purpose of an electrochemical gradient in photosynthesis?
to generate atp
to split water molecules
to absorb sunlight energy
to produce oxygen

Explanation:

In photosynthesis, the electrochemical gradient formed across the thylakoid membrane during the light - dependent reactions is used by ATP synthase to generate ATP through chemiosmosis. Splitting water molecules provides electrons and protons, absorbing sunlight energy is the role of pigments, and producing oxygen is a by - product of water splitting.

Answer:

to generate ATP
