WebFeb 28, 2024 · Negative feedback occurs when a system’s output acts to reduce or dampen the processes that lead to the output of that system, resulting in less output. In general, negative feedback loops allow systems to self-stabilize. Negative feedback is a vital control mechanism for the body’s homeostasis. bateria btx4l-bsWebfeedback inhibition, in enzymology, suppression of the activity of an enzyme, participating in a sequence of reactions by which a substance is synthesized, by a product of that sequence.
