Now, the IP three and the Dag are actually two types of secondary messenger molecules. So what fossil lipasec does is it cleaves this molecule, the pivot two, that produces two different secondary messenger molecules. Now let's discuss what the IP three does. So when the IP three is cleaved, it is readily able to dissolve in that aqueous cytoplasm. And what it does is it moves on to a special ligand gated calcium ion channel that is found on the membrane of the endoplasmic reticulum. So this is one calcium channel, a second calcium channel.
