Webbför 2 dagar sedan · This proton motive force can be provided for example by ATP synthase or proton-pumping rhodopsin, as already demonstrated in liposome systems. (13) For thermodynamically very favorable electron donating substrates (e.g., phosphite, formate, and hydrogen), the NADH/NAD + ratio that can be generated by the electron donor may … Webb18 okt. 2024 · Proton motive force (PMF) is the force that promotes the movement of protons across membranes downhill the electrochemical potential. Overview A difference of solute concentration between two compartments separated by a biological membrane generates a tendency to equilibrium, which, in the case of protons, is called proton …

WebbThe proton-motive force created by the pumping out of protons by the respiratory chain complexes is in the mitochondria of most tissues mainly used to translocate protons … WebbThe proton-motive force created by the pumping out of protons by the respiratory chain complexes is in the mitochondria of most tissues mainly used to translocate protons … WebbThe proton motive force will result in creating a proton gradient across the thylakoid membrane. If electron transport, as well as the proton gradient, is at a still, that is, they have no movement or gradations, then ATP cannot be produced. The stored energy in the proton gradient has to be drained to continue electron transportation and ATP ... slumberland ascot mattress review
