Which of the following is true of enzymes?
a. Enzyme function is independent of physical and chemical environmental factors such as pH and temperature
b. Nonprotein cofactors alter the substrate specificity of enzymes
c. Enzymes increase the rate of chemical reaction by lowering activation energy barriers
d. Enzyme function is often increased if the 3-D structure or conformation of an enzyme is altered
e. Enzymes increase the rate of chemical reaction by providing activation energy to the substrate
You have an enzymatic reaction proceeding at the optimum pH and optimum temperature. You add a competitive inhibitor to the reaction and notice that the reaction slows down. What can you do to speed the reaction up again?
a. Increase the pH.
b. Add more substrate it will outcompete the inhibitor and increase the reaction rate.
c. Increase the temperature
d. Add more inhibitor to speed up the reaction.
