Vedclass · Answer

(C) In the light reaction of photosynthesis,a proton gradient is established across the thylakoid membrane,with a higher concentration of $H^+$ inside the lumen compared to the stroma. When this proton gradient breaks down,protons move from the thylakoid lumen to the stroma through the $CF_0-CF_1$ $ATP$ synthase enzyme. This movement of protons provides the energy required for the conformational changes in the $ATP$ synthase enzyme,which facilitates the synthesis of $ATP$ from $ADP$ and inorganic phosphate $(\Pi)$. Therefore,the breakdown of the proton gradient leads to the production of more energy in the form of $ATP$.
