Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
When enzymes action stops due to a buildup of end product, this control is called
A
feedback inhibition
B
competitive inhibition
C
enzyme induction
D
enzyme repression
Explanation: 

Detailed explanation-1: -Feedback inhibition (also known as End-product inhibition) is a type of negative feedback that can be used to control metabolic pathways. End-product inhibition occurs when a reaction’s final product blocks an enzyme from a previous phase in the sequence.

Detailed explanation-2: -An enzyme also has a site which has the ability to change the shape of an enzyme and thus changing its characteristics. This site is called the allosteric site. The product(s) formed by the enzyme binds with the allosteric site and results in the inhibition of the process. This method is called feedback inhibition.

Detailed explanation-3: -Feedback regulation of an enzyme occurs when a product of the reaction binds to an allosteric site on the enzyme and affects its catalytic activity. Through feedback inhibition, the cell responds to the amount of reaction product in order to regulate its further production.

Detailed explanation-4: -Feedback inhibition is the process by where the end product terminates the reaction. The accumulation of the end product interferes with the enzymatic activity by changing the shape of its active site.

Detailed explanation-5: -End product inhibition is also known as feedback inhibition. Here the end product of a metabolic pathway inhibits the enzyme involved in early reactions. Enzymes are proteins which speed up chemical reactions.
