From the above, it is the process of communication between cells with 3 steps: 1. reception (reception) means that the cell receives a signal (signal) from outside the cell by receptor protein, which is on the surface of the target cell. Taken with the molecules of the chemical secretions out of the cell, such as a hormone, neurotransmitter if it is connected to the thyroid. The receiver is located within the cell. 2. send a signal (signal transduction) is to change the signal format. When a hormone or neurotransmitter molecules to a protein receptor catcher. Make a protein receptor changes to send a signal. 3. a response (response) is a procedure where cells are displayed. In response to a signal received, such as secretion from cells to sort out substance of Lake saiko thot graves now. Causes the cells to change shape. The response of the cells are specific chemicals because there are different types of cells, the proteins are different types of receivers. Therefore, the response depends on the type of receptor proteins of the cell. It is important to respond to the signal is the ability of a protein to change ruprangklap. So they are ready to respond when you receive the new signals.
