WebFeedback inhibition occurs when the pathway's end product (here isoleucine) inhibits an upstream enzyme (indicated by red bar). In this example, isoleucine will bind to Threonine Deaminase (at the allosteric site) and prevent threonine from binding to this enzyme’s active site, effectively blocking this metabolic pathway. WebSep 4, 2024 · Examples of processes controlled by positive feedback in the human body include blood clotting and childbirth. Blood Clotting When a wound causes bleeding, the body responds with a positive feedback loop to clot the blood and stop blood loss. Substances released by the injured blood vessel wall begin the process of blood clotting.
