Answer :
Answer: alternative C.
Explanation: The process in which the endproduct of a metabolic pathway binds to enzymes that are placed in the same pathway is called feedback inhibition. It is a strategy to diminish the production of this endproduct, regulating the whole pathway until the endproduct concentration decreases and so the production can restart. While the endproduct is binding to the enzymes, they aren't able to bind to other molecules in order to produce more of the endproduct, characterizing this method as an inhibition.
Final answer:
The process where the end product of a metabolic pathway inhibits an early enzyme in the pathway is called feedback inhibition, a type of noncompetitive inhibition. The correct option is d. a and c.
Explanation:
The process by which the end product of a metabolic pathway inhibits one of the first enzymes in the pathway is known as feedback inhibition.
This regulatory mechanism involves the binding of the end product to an enzyme early in the pathway, often at an allosteric site, which changes the shape of the enzyme's active site and prevents it from catalyzing its reaction. This is a form of noncompetitive inhibition, as the end product does not compete with the substrate for the active site but rather binds to a different site on the enzyme.
