The Enzymes Used by the Electron Transport Chain are Located

Question

The enzymes used by the electron transport chain are located:
A) in the cytosol.
B) in the outer membrane of the mitochondrion.
C) in the inner membrane of the mitochondrion.
D) between the inner and outer membranes of the mitochondrion.

Accepted Answer

The electron transport chain (ETC) is a series of membrane-bound proteins located in the inner mitochondrial membrane. These enzymes are embedded within the membrane and are responsible for passing electrons from one molecule to the next, ultimately generating ATP through the process of oxidative phosphorylation. Therefore, option C is the correct answer as it specifies the location of ETC in the inner membrane of mitochondria.
