Light ReactionsLight Reactions
What happens during step # 1 above?
Chlorophyll absorbs light energy and its electrons become excited and move to the electron transport chain
What happens during steps # 2-3 above?
The excited electrons move through the proteins of the electron transport chain
What happens during step # 4 above?
Light excites electrons on Photosystem I (accessory pigments)
Light ReactionsLight Reactions
What happens between steps 4 and 5 above?
The excited electrons move through the proteins of the electron transport chain
What happens during step # 5 above?
NADP+ and H+ are combined to form NADPH

SummarySummary
Explain what’s going on with protons above:1. _____ splits apart producing PROTONS, electrons, and oxygen.2. Protons can only leave the thylakoid through an _____________________________. The movement of protons through this carrier protein provides the energy needed to form _____ from __________.3. Some of the protons are pumped back into the thylakoid and some are used to make ________ from NADP+ and H+.
