Figure 14-13The two components of the electrochemical proton gradient

The total proton-motive force across the inner mitochondrial membrane consists of a large force due to the membrane potential (traditionally designated ΔΨ by experts, but designated ΔV in this text) and a smaller force due to the H+ concentration gradient (ΔpH). Both forces act to drive H+ into the matrix.
