WebFeedback inhibition is the inhibition of an enzyme by a reaction product. As more glucose-6-phosphate is produced, the reaction rate slows down. Hexokinase governs the rate-limiting step of glycolysis in the brain and in red blood cells. In most cells, glycolysis is regulated during reaction 3. This is important whenever the rate-limiting ... 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. dr shannon sniff
