43. Where do electrons from Photosystem I go after they get excited by light? Group of answer choices a. The high-energy electron travels down a short second leg of the electron transport chain. At the end of the chain, the electron is passed to NADP+ to make NADPH. b.They travel down a second electron transport chain and are donated to oxygen which then bonds to hydrogen ions to form water. c. The high-energy electron travels down a short second leg of the electron transport chain and they are donated to ADP, which is then converted to ATP. d. They remain excited and then they travel to Photosystem II where they get even more excited until they spontaneously combust.
