How does the entire system work?
Now, we need to answer two questions:
Is the sensitivity of the amplification module satisfying regarding to the quantity of adenylate cyclase that the signaling module can create?
What is the time of answer of our system?
Sensitivity
In the amplification module, we saw that we could get a signal if there was more than 10-6 mol/L of initial cAMP. In the signaling part, we saw that when the dipeptide is detected, it will lead to the production of adenylate cyclase. Then, when the adenylate cyclase is produced, it leads to the production of cAMP, and this will launch the amplification module. Thus, we will have:
Temporal evolution
Once activated, we need to know the time we will have to wait to start up the amplification module. We take the equations of the signaling module, when the production of adenylate cyclase is activated. We have:
