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. So once the information is passed down transduced across the cell membrane to one step two takes place, the cell reacts by increasing the production of some sort of intracellular molecule called a secondary messenger. So, for instance, one example of a secondary messenger is cyclic adenosine monophosphate. Another example of is a calcium.
