The function of the outer mitochondrial membrane is to regulate the passage of molecules.

The outer membrane is permeable to small molecules and ions due to the presence of porin proteins, which form channels. This allows the movement of molecules necessary for mitochondrial function, such as pyruvate and ATP, while maintaining the integrity of the organelle.

The other options describe functions of other parts of the mitochondria or cell:

To produce ATP: ATP production occurs in ...
