Question 4 a photon of light excites an electron in the pigment molecule of a plant. which of the following best describes what happens next to the energy from that photon? a. the energy is released as light and the electron drops back down to its ground state. b. the excited electron carries the energy to the reaction center complex and oxidizes the primary electron acceptor. c. the excited electron carries the energy to the primary electron acceptor in the reaction center complex. d. the energy is released as heat and the electron drops back down to its ground state. e. the energy is passed to the other electrons in the light harvesting complex until it reaches the reaction center complex, where the excited electron reduces the primary electron acceptor.
