How is a proton gradient formed
WebA proton gradient is formed by two quinol (4H+4e−) oxidations at the Qo site to form one quinol (2H+2e−) at the Qi site (in total six protons are translocated: two protons reduce quinone to quinol and four protons are released from two ubiquinol molecules). WebThe proton gradient produced by proton pumping during the electron transport chain is used to synthesize ATP. Protons flow down their concentration gradient into the matrix through the membrane protein ATP synthase, causing it to spin (like a water … This "proton" gradient is what drives oxidative phosphorylation.
