Question

What is the end product inhibition?

Answer 1

Hint: Inhibition is the process of stopping or slowing down the process or fact of happening. Inhibiting molecule controls, prevents, arrests and restrain the inhibitory activities. Biological inhibitors are called enzyme inhibitors. It binds to the enzyme and prevents the excretion of later its catalytic activity. It may be a biological or chemical reaction. Enzyme inhibition is the process of reducing the enzyme-related activities, enzyme production and enzyme actions.

Complete answer:
End production inhibition is also called feedback inhibition. This is the process of catalyzing the reaction of series by end product at the metabolic pathway. Here the substrate is converted into the product through an intermediate product. During the increasing concentration of the end product it diffuses into the allosteric enzyme. It produces the reduced synthesis of the product. It reduces the rate of enzymatic reaction in the remaining pathway.
If the enzyme does not function then the process will be halted. Rate of production formation is also decreased if the enzyme does not function. It releases the essential product so the level of inhibition is increased. During the product level build up then the product inhibits the new pathway so the rate of production formation will decrease. Product level drops then the pathway will be unhindered so the rate of formation is increased. So the end product inhibition is the pathway that converts threonine to isoleucine. It is known to be an essential amino acid but it is not synthesized in the human body. But in plants it is synthesized in five step pathways by threonine.

Note:
So the end product inhibition or feedback inhibition provides the isoleucine. The production of isoleucine increases and inhibits further synthesis. Threonine is the initial reactant and the end product is isoleucine. Negative feedback is also available in feedback inhibition or end product inhibition. So end product inhibition is the form of negative feedback so it controls the entire metabolic process. Metabolic process is defined as the set of chemical reactions which occur at the cell in a living organism.
