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. WebFeb 14, 2024 · Abstract. Cytochrome c oxidase (COX) is regulated through tissue-, development- or environment-controlled expression of subunit isoforms. The COX4 subunit is thought to optimize respiratory chain function according to oxygen-controlled expression of its isoforms COX4i1 and COX4i2. However, biochemical mechanisms of regulation by …
