Electron gradient in biology

Web3 years ago. Oxidative phosphorylation is a process involving a flow of electrons through the electron transport chain, a series of proteins and electron carriers within the mitochondrial membrane. This flow of … WebIn the presence of respiratory electron acceptors, however, the cell can more efficiently produce ATP by oxidizing reduced pyridine nucleotides using an exogenous terminal electron acceptor. Oxidative Phosphorylation. The synthesis of ATP from ADP can also be driven by the electrochemical gradient generated through respiratory electron transport.
