And they can basically induce and stimulate many different types of processes as we'll see in just a moment. Now, this is the second level of Amplification. So this was the first and this is the second. Why? Well, because a single G alpha protein goes on and binds to a single adenylate cyclist and then that single cyclase enzyme carries out many individual processes in which it produces many of these cyclic Amp molecules. So we have a ton of these cyclic Amp molecules that then can diffuse into different regions in the cell.
