Detailed explanation-1: -Electron transport chain (ETC) occurs in the inner mitochondrial membrane, where the OXPHOS takes place through the action of ATP synthase, [37].
Detailed explanation-2: -The ETC is a collection of proteins bound to the inner mitochondrial membrane and organic molecules, which electrons pass through in a series of redox reactions, and release energy. The energy released forms a proton gradient, which is used in chemiosmosis to make a large amount of ATP by the protein ATP-synthase.
Detailed explanation-3: -The inner membrane forms numerous folds (cristae), which extend into the interior (or matrix) of the organelle. Each of these components plays distinct functional roles, with the matrix and inner membrane representing the major working compartments of mitochondria.
