Which of the following best explains why this decrease occurs?a. The allosteric inhibitor causes free energy change of the reaction to increaseb. The allosteric inhibitor binds to the active site, preventing the substrate from binding.c. The allosteric inhibitor binds to the substrate and prevents it from binding at the active site.d. The allosteric inhibitor stabilizes the inactive form of the enzyme that prevents the substrate from binding at the active site.e. The allosteric inhibitor lowers the temperature of the active site.

The right answer is d. The allosteric inhibitor stabilizes the inactive form of the enzyme that prevents the substrate from binding at the active site

Explanation:

An allosteric inhibitor is a molecule that causes a decrease in enzyme activity through its interaction with the enzyme. This kind of molecules binds to the enzyme (in a place different from the active site) causing a change in the conformation of the enzyme, particularly in the active site. Because of thet, the enzyme cannot bind to its substrate and the reaction does not happen, reducing the rate of enzyme activity.
