Describe the process of events involved in ligand production

Describe the process of events involved in ligand production to exocytosis. Different cells can react differently to the same signal. Briefly discuss with an example

Solution

B. The number of signals is so vast, and the types of things that different cells do so varied, that it makes sense to limit each cell type to certain kinds of receptors. Even with a limited set of receptors, cells can respond to a stunning range of signals with a great variety of responses. This is because:

a. A single signal can bring about a variety of responses in a target cell
b. Each signal is passed on from the receptor, through the cell\'s messenger system, to bring about the cell\'s response. Since these messengers that relay the signal can vary depending upon cell type, different cells may respond differently to the same signal.
c. Since a given cell has dozens of different receptors, it is capable of receiving dozens of signals at once. The presence of one signal can affect the response to another signal. This means the cell can have different responses depending on the combinations of signals received.
