Negative feedback control mechanisms (used by most of the body's systems) are referred to as ânegativeâ because the information caused by the feedback results in a reverse of the response. TSH is an example: blood levels of TSH serve as feedback for production of TSH. Positive feedback control is used in some cases.
Feedback inhibition occurs when the end product of a reaction interferes with the enzyme that helped produce it. The inhibitor does this by binding to a second active binding site that's different from the one attached to the initial reactant. The enzyme then changes its shape and can't catalyze the reaction anymore. This type of inhibition is done as a regulatory mechanism to meet the metabolic needs of the cell or organism.
