The enzyme is inactive at this point. New enzyme must be added to regain enzyme activity
There are two ways wherein cells regulate the activity of enzymes. These involve controlling the amount of the enzyme and controlling the activity level of the enzyme.
When an enzyme is frozen, it only slows down activity. Unlike boiling an enzyme, it does not stop it from working.
Cold temperatures have a drastic effect on an enzyme's activity level. Cold temperatures usually dramatically slow down an enzyme's activity.
An allosteric inhibitor stops enzyme activity by binding to an allosteric site and causing the conformation of the enzyme to change.
Enzyme activity sometimes reflects the amount of protein expressed in a cell--however, due to enzyme inhibitors, the enzyme activity is not always reflective of the amount of protein expressed by a cell.
Tests that measure enzyme activity generally reflect the genetic capabilities of the cell.
Increase the amount of substrate for the enzyme.

Denature enzyme activity
pH Temperature Substrate Concentration non-ideal conditions will ultimately lead to the denaturing of the enzyme
Physical activity can alter the shape of enzyme which can cause damage or may the enzyme become inactive
Warmer temperatures mean little more than that molecules are moving more rapidly. This promotes enzyme activity on its own, however, as movement allows the enzymes to react to more material in a shorter amount of time.
