Question

Biochemistry- If an enzyme is operating at very high substrate levels, and an irreversible site specific inhibitor is added, so that the reaction rate is reduced by 50%, what is true about the resulting condition of the enzyme and/or substrate?

A. Half of the substrate does not bind to the enzyme.

B. The Km of the enzyme has changed by 50%

C. All of the enzyme molecules exhibit a 50% loss of activity

D. Half of the enzyme molecules are completely active and half of the enzyme molecules are completely inactive

E. The binding affinity of the substrate is different for all of the enzyme molecules.

Explanation / Answer

enzyme inhiitor are the compounds ,which decreases the catalytic activity of enzyme or some times stop the process.

inhibitor attack the enzyme and it starts the decrease the catalytic activity i.e half of the enzyme moluces is incative and remaning enzyme molecules already participated in reaction. so rate of raection is decreses. so the answer is D.
