WebThis causes a lessening in the PMF, which disperses the proton slope and diminishes the possible energy from the proton thought process force. Since the proton rationale force is important for ATP union, this lessening in potential energy will prompt a reduction in ATP blend, since there could be as of now not a similar proton slope to drive the ATP synthase … WebOverview. 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 motive force (PMF). This is measured in terms of the potential energy resulting from the difference in concentration between the two compartments.
