What are the light and dark reactions of photosynthesis?
Starts with the light energy hitting photosystem number 2 and that light energy from the sun is passed between the antennae molecules inside the photosystem. Then, once the light energy is finally hit to the center molecule, called the reaction center, it makes the electrons in the center molecule to become excited, or to contain alot of energy. Since, the electrons contain so much energy they are released into and electron transport chain. In the electron trapsport chain the electrons are passed between each acceptor as it releases energy. The released energy forms a concentration gradient that makes the H ions move through the thylakoid membrane and then the energy from the concentration gradient energy moves the H ions across the membrane and down the ATP synthase (this process is also called chemiosmosis). then the energy from that photophosphorylates ADP into ATP.
