How is ATP used in photosynthesis?
That's interesting. Can you explain the light-dependent reactions in more detail?
Of course! The light-dependent reactions occur in the thylakoid membrane of the chloroplasts and involve the conversion of light energy into ATP and NADPH, two molecules used in the light-independent reactions. Protons are also pumped from the stroma to the thylakoid lumen, creating an electrochemical gradient that is used to power ATP synthesis.
