The active transport of protons against the proton gradient requires energy released from redox reaction in the ETC. If the strength of proton motive force increases above the energy released by the redox reactions, then transport of protons will be halted. When this occurs, electron transport will slow down or stop.
Note: Movement against the gradient require acxtive transport and active transport always requires energy. Hre energy is coming from redox reactions occurs during electron transport chain. If the required energy (strength of proton motive force) to move the proton against gradient will be increased above the energy released by the ETC redox reaction then the proton movement will be halted which will result into slow down or stoppage of ETC.
