The three types of communication are direct, local, and long distance. Language can be analogous with specificity because cells need to understand each other. Certain cells have certain receptor sites for specific tasks. Some cells have receptors, but some don’t. Only those with correct receptors can respond. Cells become specialized for local signaling by having receptor proteins. The receptor protein ER and transported to the plasma membrane. The code for receiving the signal is there, but it is not turned on. The code for producing anything is there. “Lars” and his daughter ring the doorbell and act as the growth factor. Her daughter acts as the receptor and sends the message to Dr. Maas (phosphorylation cascade known as transduction).
