Where do electrons get their energy in photosystem i? a. from nad and nadph b. from energy in photons c. from adp and atp d. from glucose in the calvin cycle

That would be B. From energy in photons.

Photons(from sunlight) give energy to electrons and “excite” them(sending them to a higher energy level). Electrons can then release this energy and excite other electrons in other chlorophyll molecules.

Cis correct i think

Is there any answer choices?
