The proton-motive force is
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 ... Webb10 okt. 2011 · The proton motive force is composed of two components that depend on the magnitude of the transmembrane electric potential difference (ΔΨ) and the pH gradient across the membrane. In vivo, the pH gradient is determined by the buffering of the external environment and by pH homeostasis mechanisms to control the internal pH.
