Webb25 aug. 2024 · The proton motive force occurs when the cell membrane becomes energized due to electron transport reactions by the electron carriers embedded in it. Basically, this causes the cell to act like a tiny battery. Its energy can either be used right away to do work, like power flagella, or be stored for later in ATP. WebbThis proton motive force (Δp) drives the activity of the ATP synthase and has both an electrical component, the mitochondrial membrane potential (ΔΨ (m)), and a chemical component, the mitochondrial proton gradient (ΔpH (m)). Webb3 jan. 2024 · We say that the proton gradient has a proton-motive force, resulting from the difference in proton concentration (an H+ or pH gradient) and a difference in electric potential. The use of this force to make ATP is regulated. Conditions in the cell control when the energy stored in this gradient will be released to make ATP. imsh briefcase
