Question

the immediate source of energy for atp synthesis in chloroplasts is ________, while the ultimate source of energy for atp synthesis in chloroplasts is ________. electron transport; a proton gradient nadph; energized chlorophylls nadph; electron transport a proton gradient; light light; electron transport

Explanation:

In chloroplasts, ATP synthesis occurs via chemiosmosis. The immediate energy source is the proton - motive force (a proton gradient) generated by the electron - transport chain. The ultimate source of energy is light energy which is captured by chlorophylls to drive the electron - transport chain and subsequent proton gradient formation.

Answer:

a proton gradient; light
