Cytochromes c
WebDuring the process of electron transfer, a proton gradient is formed across the membrane due to three potential processes: 1. The use of some of the energy associated with the electron transfer for active pumping of protons across a membrane. 2. Exporting protons out of the cell during electron-to-hydrogen transfers. 3.
