Pepsin is an enzyme produced in the stomach. Pepsin has an optimum pH that is very acidic, between a pH of 1.0 and 2.0. in an experiment involving the enzyme pepsin, the pH is raised from 2 to 11. What will be the MOST LIKELY effect of this on the reaction? a) the enzyme will denature, stopping the reaction.
b) the activation energy of the reaction would be reduced.
c) the rate of reaction will reduce due to a decrease in the kinetic energy of the molecules.
d) the rate of reaction will increase due to the increased number of collisions of the enyzme and substrate.
