10. When light strikes a pigment molecule in Photosystem II (PS II), the energy excites electrons out of place to higher energy level. This is known as: a. Photolysis b. Photoactivation c Photosynthesis d: Photogeneration​
A photon strikes photosystem II to initiate photosynthesis. Energy travels through the electron transport chain, which pumps hydrogen ions into the thylakoid space. This forms an electrochemical gradient.
