Chemiosmosis/Photophosphorylation produces ATP

//H+ from photolysis remain in thylakoid space
ETC releases energy
Used to pump H+ from stroma into thylakoid space
By active transport and electrochemical gradient
H+ conc in thylakoid space > stroma
H+ ions pass back from space between two thylakoid membranes
Through pores which are associated with the enzyme ATP synthetase
Energy from the ETC will be used to produce ATP
Diffuse down conc gradient across thylakoid membrane
Produces ATP by photophosphorylation
