A chemistry student needs to determine the rate constant (k) and the initial rate (vo) of an enzymatic reaction that follows Michaelis-Menten kinetics. The reaction involves the conversion of substrate A to product B in the presence of an enzyme that is inhibited by a competitive inhibitor. The student should also calculate the inhibition constant (Ki) of the inhibitor and determine the type of inhibition (competitive, non-competitive or uncompetitive).
