So this is basically step number two. The formation of that receptor primary messenger or ligand complex is what we call step two. And what happens in step two is that message that is stored in that primary messenger is now transduced passed down to that cell. Now that the binding took place, the cell nodes to carry out specific types of processes. So what happens next is the following step three. And in step three, as a result of this process that cell begins to increase the concentration of some type of molecule found inside the cell some type of intracellular molecule we call the secondary messenger.
