Answer:
The mecanism is termed as feedback inhibition.
Explanation:
In an enzyme catalyzed sequential reaction the end product of that reaction inhibits the activity of the activity of the enzyme catalyzing the ist step This type of regulation is called Feed back regulation or feedback inhibition.
The main function of human body is to maintain the homeostasis of the all the components it contains.When the end product of an ongoing enzyme catalzsed sequential reaction is produced in a high lebel at that time to maintain its own homeostatis that end product inhibits the functioning of the enzyme catalzsing the ist step of that biochemical reaction.
For Example Cytidine tri phosphate inhibits the activity of aspartate transcarbamoylase catalyzing the de novo biosynthesis pathway of pyrimidine metabolism.
