Would you help me with the given question?
An enzyme catalyzes a reaction at a velocity of 20 umol/min when the concentration of substrate (S) is 0.01 M. The Km for this substrate is 1 x 10-5 M. supposing that Michaelis-Menten kinetics is followed, and then what will be the reaction velocity when the concentration of S is:
a) 1 x 10-5 M
b) 1 x 10-6 M.
