almond37 [142]

Answer:

The correct answer is option C, that is, increase the concentration of the enzyme.

Explanation:

In the given case, if the enzyme gets saturated with the substrate, and is working at optimum pH and temperature, then to enhance the rate of the reaction the only thing that can be done is to enhance the concentration of the enzyme. However, further stimulation of some of the enzymes can be done with the addition of allosteric activators in the reaction, otherwise, enhancing the concentration of the enzyme is the only way.
