2. Which division of the nervous system is responsible for restoring the body to normal function following a stressful event?
A. parasympathic nervous system
B. somatic nervous system
C. sympathetic nervous system
D. visceral nervous system

The answer is;  C

An allosteric protein does not bind to the active site of an enzyme. Only the subtrate binds the active site. However, some enzymes have an allosteric site where the allosteric protein binds and influences the conformation of the enzyme. This change in conformation on binding may facilitate or inhibit the binding of subtrate to the enzyme active site. Therefore, there are two type of allosters; inhibitors and activators.
