Excited by light energy, the pair of chlorophylls in this structure donates an electron to the primary electron acceptor, which passes an electron to an electron transport chain.Group of answer choicesrubiscoreaction-center complexNAD⁺/NADHlight-harvesting complexprimary electron acceptorphotosystem

A light-capturing unit in a chloroplast’s thylakoid membrane that has two molecules of P680 chlorophyll a at its reaction center. (It is called P680 because this pigment is best at absorbing light having a wavelength of 680 nm).Group of answer choicesPEP carboxylaseprimary electron acceptorphotosystemrubiscoreaction-center complex
