Answer:
Answer is enzyme repression.
Step-by-step explanation:
The prevention of the synthesis of enzyme as a mechanism of regulating enzyme production by repressors is known as enzyme repression.
It can also be explained a situation whereby protein molecules, which is known as the repressor , does not allow the synthesis of an enzyme.
An enzyme repressor is a protein molecule decreasing the rate of enzyme biosynthesis which negatively regulates the amount or number of enzyme.
