Question

nadph is made as a result of: multiple choice the establishment of a proton gradient. the calvin cycle. the direct absorption of photons by nadp reductase. the electron transport chain that follows photosystem i.

Explanation:

In photosynthesis, the electron - transport chain that follows photosystem I reduces NADP+ to NADPH using electrons and protons. The establishment of a proton gradient is mainly related to ATP synthesis. The Calvin cycle uses NADPH. NADP reductase does not directly absorb photons.

Answer:

the electron transport chain that follows photosystem I.
