Question

Which of the following statements describes the mitochondrial outer membrane?
A)It is permeable to molecules with molecular mass as high as 5000 daltons.
B)It contains transporters for ATP molecules.
C)It contains proteins that are released during apoptosis.
D)It contains enzymes required for the oxidation of fatty acids.

Accepted Answer

The mitochondrial outer membrane is permeable to small molecules and ions, including those with molecular masses up to about 5000 daltons, due to the presence of porin proteins.
