A vortex was used to thoroughly mix the solutions. Color changes and reactions were noted. Green Note that the cabbage juice and the cabbage juice mixed with dH20 both have a pH level of 7, even though the cabbage juice was also added to the other substances. The more basic solutions generated more of a reaction than the acidic solutions. Enzymes involved directly in this project are ptylain, bromelain, and catalase.
Enzymes are very selective in the reactions they catalyze.
Their selectivity determines which chemical processes occur in a cell at any particular time. The activity of an enzyme is effected by its environment, and for every enzyme there are conditions under which it is most effective. Temperature for instance, affects molecular motion, and an enzyme's optimal temperature produces the highest rate of contact between reactant molecules and the enzyme's active site. Enzymes have a higher activity rate in regards to temperature. This is commonly referred to as enzyme kinetics.
