WebFeedback inhibition is a process by which the products of a reaction or series of reactions slows, stops or inhibits one of the previous reactions in the process, thereby controlling the rate of reaction, and rate of formation of the products. In glycolysis, one of the end products is energy in the form of ATP. WebOn the other hand, a negative feedback involves the inhibition or deactivation of a certain pathway due to the presence of its end product. Increase in the concentration of the product will lead to a proportional …
