Summary Introduction
To review:
The differences between polar and nonpolar regulatory molecules based on location and action mechanism.
Introduction:
The process of cell signaling is also known as signal transduction. This process is employed by cells in order to communicate with each other as well as their environment. It is a mechanism by which stimuli are transmitted via signaling cascade to the effector molecule. There are numerous types of regulatory molecules which act on their specific target cells.
