Explanation In polypeptides, there are several amino acids attached to each other in a chain. They are water-soluble molecules, so it can’t enter into the cell membranes. Therefore, they deliver their message from outside of the cell by binding to the cell receptors, thereby a message is passed in inside the cell to secrete enzymes. For example, Insulin is an example for a polypeptide hormone generate by pancreas when the glucose concentration in the blood is high...
