    'Some researchers treated isolated mitochondria by placing then in solutions of very low water potential so that the outer membrane ruptured, releasing the contents of the intermembrane space. By further treating the resulting mitoblasts ( mitochondria stripped of their outer membranes) with strong detergent, they could rupture the inner membrane and release the contents of the matrix'. Why didn't the solution of low water potential also rupture the inner membrane?

    I did a quick wiki search on the membranes.
    The outer membrane apparently contains many porins allowing for diffusion of substances through the phosphlipid.
    However the inner membrane seems to have a more controlled method of allowing molecules through, this may explain why the outer membrane was easier to rupture.

    Thank you from your answer it doesn't seem like you haven't studied A2 biology yet
