The binding of an allosteric inhibitor to an enzyme causes the rate of product formation by the enzyme to decrease. Which best explains why this decrease occurs

Due to change in active sites of enzymes.

Explanation:

The binding of an allosteric inhibitor to an enzyme causes decrease in the rate of product formation by the enzyme because the allosteric inhibitor changed all the active sites of enzyme which is responsible for the increase in the rate of product formation so due to this change the enzyme is unable to perform their function well so decrease occur in the rate of product formation.
