Answer:

Hi Archana,

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