# Is homeostasis a type of dynamic equilibrium?

Aug 7, 2014

No, homeostasis is not a type of dynamic equilibrium, but the two concepts have similarities.

Homeostasis is the maintenance of a constant internal environment. When a change is made to this environment it restores the environment to its original condition. For example when blood glucose levels rise above a certain threshold the body releases insulin to stimulate the uptake of glucose from the blood into muscle and fat tissue until it falls back into the acceptable range. Homeostasis also regulates other factors such as body temperature and blood pH.

Dynamic equilibrium refers to the extent to which a chemical reaction occurs. Most chemical reactions occur in both directions. Some of the product is reacting to form products and simultaneously some of the product is reacting to form reactants.

For example:

${N}_{2} + 3 {H}_{2} r i g h t \le f t h a r p \infty n s 2 N {H}_{3}$

The double arrows indicate that the reaction proceeds in both directions. When the rates of forward and back reactions are equal the system is considered to be in equilibrium
