Furthermore, homeostasis is a self-regulating process that regulates internal variables necessary to sustain life. That is, movement of signaling molecules give local regulation at best occurs via diffusion. It is because of this regulation that certain proteins are synthesized in as few as 5-10 molecules while others are formed in more than 100,000 molecules per cell. This type of regulation is particularly characterized by the fact that the effector (the substance which activates or inhibits the enzyme) and the substrate of this enzyme are generally not isosteric., i.e. For example, living things can regulate their own internal salinity level, temperature, moisture and what comes in and out of the cell(s).
