1.	Three cellular processes are listed below. Choose the correct combination of processes that involve proton gradient across the membrane.I. PhotosynthesisII. Aerobic respirationIII. Anaerobic respiration(a) II and III(b) I and II(c) I, II and III(d) I and III
Answer» Answer is : (b) I and II In photosynthesis, photophosphorylation and in aerobic respiration, oxidative phosphorylation occurs that requires proton gradient. The sunlight-driven production of ATP from ADP and inorganic phosphate is called photophosphorylation. It occurs in the chloroplast. Oxidative phosphorylation is the process in which ATP is formed by the transfer of electrons from NADH or FADH₂ to O₂ by a series of electron carriers. It occurs inside the mitochondria.

Answer is : (b) I and II

In photosynthesis, photophosphorylation and in aerobic respiration, oxidative phosphorylation occurs that requires proton gradient. The sunlight-driven production of ATP from ADP and inorganic phosphate is called photophosphorylation. It occurs in the chloroplast. Oxidative phosphorylation is the process in which ATP is formed by the transfer of electrons from NADH or FADH₂ to O₂ by a series of electron carriers. It occurs inside the mitochondria.
