Detailed explanation-1: -So, the correct statement is ‘The carrier molecules of the electron transport system are located in the inner membrane of mitochondria.

Detailed explanation-2: -The inner mitochondrial membrane containing the enzymes of the respiratory electron and proton transport chain that leads to the production of ATP, including five multiprotein enzyme complexes (I–V) and two electron carriers –coenzyme Q10 and cytochrome c.

Detailed explanation-3: -Final answer: “The enzymes of the electron transfer chain embedded in the outer membrane” statement regarding the mitochondrial membrane is not correct.

Detailed explanation-4: -The electron transport chain is a series of proteins and organic molecules found in the inner membrane of the mitochondria.

Detailed explanation-5: -The electron transport chain is located in the mitochondria. There are five main protein complexes in the ETC, located in the inner membrane of the mitochondria. These are labelled Complexes I, II, III, IV and V.
