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 electron transport chain is a series of proteins and organic molecules found in the inner membrane of the mitochondria.
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.
Detailed explanation-4: -At the inner mitochondrial membrane, a high energy electron is passed along an electron transport chain. The energy released pumps hydrogen out of the matrix space. The gradient created by this drives hydrogen back through the membrane, through ATP synthase.
