The proton-motive force is
Webb23 aug. 2011 · The low proton conductance of the inner mitochondrial membrane allows protons to accumulate outside the matrix space forming an osmotic force (also defined as the proton motive force or Δp). The re-entry of protons into the matrix space via the ATP synthase, located in the inner membrane, induces conformational changes that catalyze … Webb1 juni 2024 · The proton motive force (PMF) consists of the electric potential difference (Δψ), which is measured as membrane voltage, and the proton concentration difference (ΔpH) across the cytoplasmic membrane. The flagellar protein export machinery is composed of a PMF-driven transmembrane export gate complex …

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 ... Webb5 mars 2024 · The proton motive force responsible for production of ATP in cellular respiration depends on the concentration gradient of H + across the plasma membrane …
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.
