Photosynthesis

Light Dependent Reaction

(Thylakoid Membrane)

In Photosystem

Electrons in the chlorophyll are hit by sunlight and excited.

Sunlight (Photons)

Energy bounces from Chlorophyll to chlorophyll until it gets to Chlorophyll-a

Electron from chlorophyll-a goes into the primary electron acceptor

Replacement electron taken from water

Electron goes to electron transport chain

Oxygen leaves as waste product

Proteins of the ETC pump protons into the thylakoid using energy taken from the electrons

Creates a high conc. of

protons inside the thylakoid
