Question

Feedback inhibition is cell’s mechanism to _____________ the process of anabolism.

(a) activate

(b) inhibit

(c) increase

(d) decrease

This question was addressed to me during an interview for a job.

My question is based upon Bioenergetics in chapter Bioenergetics, Enzymes, Metabolism, Genes, Chromosomes and Genomes of Cell Biology

Answer 1

Right answer is (b) inhibit

Explanation: Feedback inhibition acts as a check point. If the formation of products is too much, the product itself acts as the inhibitor of the enzyme thus causing the reaction to stop. Feedback inhibition loop is found in most of the cell’s anabolic and catabolic processes.
