An enzyme has an optimal pH of 7.1 and an optimal temperature at 37° C. Which statement describes a reaction catalyzed by this particular enzyme at a constant temperature of 20° C? there is no effect the enzyme will be denatured the reaction will be slower than if it ran at 37° C the reaction will slow down and then increase as the temperature increases the enzyme will provide an alternate active site so the reaction can proceed
