Question

A researcher designs an experiment to investigate the effect of environmental temperature on the function of an enzyme. For each trial included in the experiment, the researcher will add the enzyme and its substrate to an aqueous buffer solution and then measure the amount of product formed over 20 minutes.
Which of the following must remain the same for all trials in this experiment?

a. The initial concentration of the substrate
b. The final concentration of the product
c. The three-dimensional structure of the enzyme
d. The temperature of the aqueous buffer solution

Answer 1

Answer:

a. The initial concentration of the substrate

Explanation:

If the researcher keeps the initial concentration of the substrate constant, it will give room to compare the reaction rates under different environmental conditions. The reaction rates will assist the researcher by providing the researcher with the necessary and important information about the enzyme's function in different environments.
