True or False
Oxidative phosphorylation is the last step of aerobic respiration in which ATP molecules are produced from the energy generated during the electron transfer occurring during series of redox reactions. It has two components: the electron transport chain (ETC) and chemiosmosis.
The ETC consists of a series of integral membrane proteins of the inner mitochondrial membrane. Electrons from NADH and FADH2 produced during the previous steps of respiration are shuttled through the proteins of ETC and oxygen acts as a final electron acceptor at the end of the ETC. This is accompanied by the pumping of protons from the mitochondrial matrix across the membrane into the intermembrane space. This results in a proton gradient across the inner membrane of the mitochondria. The potential energy present in this gradient is used in ATP generation by another membrane transporter protein called ATP synthase.
