Question

The term 'feed back' refers to the effect of

• A. Substrate on the rate of enzymatic reaction
• B. End products on the rate of enzymatic reaction
• C. Enzyme concentration on its rate of reaction
• D. An external compound on the rate of enzymatic reactions

Answer 1

The correct option is B End products on the rate of enzymatic reaction

Feedback mechanism is a regulatory mechanism for the enzyme action where the end product inhibits the action of the enzyme when its concentration exceeds the need of the cell. This helps to maintain the homeostasis.

So, the correct answer is option B.
