Vedclass · Answer

(C) Let us analyze each statement based on the chemiosmotic hypothesis of photosynthesis:$(a)$ The $F_{0}$ part of $ATP$ase is an embedded membrane protein that provides a channel for protons to move across the membrane,leading to the breakdown of the proton gradient. This statement is correct.$(b)$ As electrons move through the $ETS$,protons are pumped from the stroma into the lumen. $A$ $H^+$ carrier (like $Cytochrome$ $b_6f$ complex) is involved in this process,thus contributing to the creation of the proton gradient. This statement is correct.$(c)$ The movement of electrons through the $ETS$ is indeed coupled to the pumping of protons from the stroma into the thylakoid lumen,which establishes the proton gradient. This statement is correct.$(d)$ The formation of $NADPH + H^+$ occurs on the stromal side of the thylakoid membrane. This process consumes $H^+$ ions from the stroma,which contributes to the maintenance of the proton gradient across the membrane. This statement is correct.Since all four statements $(a, b, c, d)$ are correct,the total number of correct statements is four.
