I got this question at a job interview.

My question comes from Allosteric Enzyme topic in portion Enzymes of Enzyme Technology

Answer 1

Correct answer is (c) negative effectors

The best I can explain: Effectors that inhibit enzyme activity are termed as negative effectors. Whereas those increase the enzyme activity are referred to as positive effectors. Regulatory metabolites are called modulator or modifier or effector. Substances which causes reduction in the rate of an enzyme catalyzed reaction is known as inhibitor.
