Now, once this ADP moves out of that binding pocket, an ATP shown in blue with a negative four charge can actually move into this pocket. Once it moves into the pocket, another aversion takes place opposite to the one that took place here. So now that the binding pocket faces the cytoplasm side and not the matrix side. So now, once this takes place, the ATP can leave this binding pocket into the intermembrane space and then move into the cytoplasm via a protein found on the outer membrane of the mitochondria known as the mitochondrial porin. And once we get to this stage, the cycle can basically repeat itself. Now, one last thing I'd like to mention about the movement of these ADP ATP molecules is the following.
