Question

Q2-What is the feedback inhibition of the enzyme function?

Answer 1

Feedback inhibition is negative regulation: it prevents an enzyme from acting. In feedback inhibition, an enzyme acting early in a reaction pathway is inhibited by a late product of that pathway. Thus, whenever large quantities of the final product begin to accumulate, this product binds to the first enzyme and slows down its catalytic action, thereby limiting the further entry of substrates into that reaction pathway. Where pathways branch or intersect, there are usually multiple points of control by different final products, each of which works to regulate its own synthesis. Feedback inhibition can work almost instantaneously and is rapidly reversed when the level of the product falls.
