*.Chemiosmotic hypothesis explain the mechanism of ATP synthesis in chloroplast.
*.In photosynthesis, ATP synthesis is linked to development of a proton gradient across a membrane.
*.The protons that are produced by the splitting of water are accumulated inside of membrane of thylakoids (in lumen).
*.As the electron moves through the photosystem, protons are transported across the membrane.
*.NADP reductase enzyme is located on thestroma side of the membrane, along with electrons from the acceptor it removes H+ from the stroma during reduction of NADPH + H+.
*.This creates proton gradients across the thylakoid membrane as well as a measurable decrease in pH in the lumen.
*.ATPase has a channel that allows diffusion of protons back to stroma across the membrane.
*.This releases energy to activate ATPase enzyme that catalyses the formation of ATP.
