The correct answer is C) mitochondrial inner membrane
Explanation:
The proteins involved in the electron transport chain is located in the inner mitochondrial membrane. There are four protein complexes present in the inner mitochondrial membrane which makes the electron transport chain.
NADH dehydrogenase, succinate coenzyme Q reductase, coenzyme Q- cytochrome c reductase, cytochrome c oxidase are the 4 enzyme complex that are present in the inner mitochondrial membrane and makes electron transport chain.
NADH is the reduced molecule which feeds electron in the ETC and the final electron acceptor is oxygen. So the right answer is C.
Proteins of the electron transport chain present in the mitochondrial inner membrane. The electron transport chain at the inner mitochondrial membrane forms a proton gradient, which is driving the synthesis of ATP with the help of chemiosmosis.
Oxygen forms water by accepting electrons, and picking up protons, and it sits at the end of the ETC. In the absence of oxygen ETC will stop running, and chemiosmosis will no longer able to produce ATP. Cells are not able to carry out the reaction they need to function, and may die after a long period, in the absence of ATP.
