almond37 [142]

Answer:

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

Explanation:

Biological molecules or proteins that enhance the rate of a chemical reaction taking place within the cell are known as enzymes. These proteins play an essential part in the proper functioning of the body, as they help in the process of metabolism and digestion.  

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.
