And let's begin with this diagram here. So we have the inner mitochondrial membrane, the matrix side, and the intermembrane size, also known as the cytoplasm side. So basically, in step one, the binding pocket that is formed by these two polypeptide chains that make up the ATP ADP translocase is open to the cytoplasm side. Now, this molecule with a negative three charge, that's the ADP. And it moves into this pocket. And once it moves into the pocket, it creates a conformational change that essentially stimulates a process we call aversion.
