So this is very likely to actually take place. Now, once this takes place, now there's room for the carbon dioxide to basically enter the active side, the pocket of that enzyme. So this transforms a weak nuclear file into a very powerful nuclear file. So, once again, as the H plus ion basically leaves the oxygen we transform the water molecule, a poured nuclear file, into a good nuclear file, a strong nuclear file that hydroxide. And now the carbon dioxide basically enters the active side. Now, as the carbon dioxide enters the active side what happens is the oxygen of that hydroxide attached to the zinc acts as a nuclear file attached the carbon of that carbon dioxide and that displaces one of the pip bonds between carbon and oxygen.
