Correct Answer: Enzymes provide activation energy for reactions
2. The equation for the rate of product formation for simple enzyme reaction is given by (Where rmax, maximum reaction rate, Cs substrate concentration, Cp product concentration ES, CES enzyme-substrate concentration)
6. An enzyme has a Km of 4.7 x 10-5M. If the Vmax of the preparation is 22m moles liter-1 min-1, what velocity would be observed in the presence of 2.0 x 10-4M substrate and 5.0 x 10-5M of a competitive inhibitor?
Correct Answer: the rate at which the enzyme can convert substrate to product
10. If a reaction occurs in the absence of inhibitor with rate ?0 and in the presence of inhibitor with rate ?i, the degree of inhibition is defined as
