So we have alpha unit here, alpha unit here and alpha unit here. And we have our beta units, the beta unit here, beta unit here and beta unit here. So let's begin by focusing on these alpha subunits. Now, the alpha subunits, even though they're part of the hexama ring, they don't actually play a catalytic role. And even though these alpha units can in fact bind ATP molecules and they will have ATP molecules bound to them, they will not actually release the ATP molecules nor will they carry out any useful process. So although the alpha subunits of the hexamarine do contain ATP molecules bound to them, they do not release these ATP molecules nor will they actually carry out or participate in some reaction some useful reaction.
