WebbIn bacteria, the extrusion of protons by the electron transport chain results in an electrochemical gradient of protons, known as the proton motive force (PMF), generated across the cell membrane. …. The PMF is made up of the sum of two param- eters: the electric potential (DJ) and the transmembrane proton gradient (DpH). Webb14 nov. 2024 · Explanation: When hydrogen ions are pumped from the mitochondrial matrix across the inner membrane and into the intermembrane space, the result is the creation of a proton-motive force. The proton gradient generated by proton pumping during the electron transport chain is a stored form of energy.
