And that's exactly right. So about 15% of the protein content of the inner mitochondrial membrane consists of ATP ADP Trams LoCASE. So now let's take a look at the following mechanism by which the ATP ADP translocase actually moves these two molecules across the inner mitochondrial membrane. 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.
