Where is ATP Synthase Located in the Mitochondrion

Question

Where is ATP synthase located in the mitochondrion?
A)cytosol
B)electron transport chain
C)outer membrane
D)inner membrane
E)mitochondrial matrix

Accepted Answer

ATP synthase is located in the inner membrane of the mitochondrion. This is where it is involved in the production of ATP through the process of oxidative phosphorylation, which occurs in the electron transport chain. The outer membrane surrounds the mitochondrion and is permeable to small molecules, while the mitochondrial matrix is the space inside the inner membrane where many metabolic reactions take place.
