A cell may vary the rate of an enzyme controlled reaction by:

According to the given question, we can see that we need to show how a cell can vary the rate of a reaction which is controlled by an enzyme.

As a result of this, we can see that there are different ways through which a cell may control the rate of reaction in an enzyme controlled state which are by the level of degradation with time.

A cell may vary the rate of an enzyme controlled reaction by making more/less or degrading more/less.

Explanation:

A cell may vary the rate of an enzyme controlled reaction by making more/less or degrading more/less. Several factors affect the rate at which enzymatic reactions proceed include post translational modifications, substrate concentration, cofactors, temperature, pH, locations. The shape and structure of the enzyme will change as the pH value of the reaction medium changes.
