WebEnzymes are a linear chain of amino acids, which give rise to a three-dimensional structure. The sequence of amino acids specifies the structure, which in turn identifies the catalytic activity of the enzyme. Upon … WebThe prediction for the effects of temperature on the enzyme activity was that the reaction’s rate would increase as the temperature increased, until they go over the optimum temperature where the enzymes denature and the reaction’s rate quickly drops to zero. At 5 degree C the rate is 0.00059 mole PNP/min.
