In bacterial photosynthesis, how would the light energy be used if the reduced bacteriopheophytin (BPh ^- )returned the electron to the P960⁺ cytochrome? A) It would follow a separate electron-transport chain. B) It would be lost as heat. C) It would stimulate the ejection of a second electron. D) A proton would be pumped. E) None of the answers is correct.

If the reduced bacteriopheophytin returned the electron to the P960, the energy would be lost as heat, as there would be no productive use of the electron in terms of generating a proton gradient or driving an electron transport chain.
