Question

You have added an irreversible inhibitor to a sample of enzyme and substrate. At this point, the reaction has stopped completely. What can you do to regain the activity of the enzyme? a. Removing the irreversible inhibitor should get the reaction working again.
b. Adding more substrate will increase the rate of reaction.
c. Adding more inhibitor should get the reaction up to speed again.
d. The enzyme is inactive at this point. New enzyme must be added to regain enzyme activity.

Answer 1

Answer:

The correct answer is d. The enzyme is inactive at this point. New enzyme must be added to regain enzyme activity.

Explanation:

This is because the inhibitor is irreversible, meaning that the enzyme is permanently modified, therefore, even if more substrate is added, the enzyme will no longer be able to work properly. If all of the inhibitor is consumed, adding more enzyme would regain the activity of the enzyme.
