We describe a computer tutorial that introduces the concept of the steady state in enzyme kinetics. The tutorial allows students to produce graphs of the concentrations of free enzyme, enzyme-substrate complex, and product versus time in order to learn about the approach to steady state. By using a range of substrate concentrations and rate constants, students are able to simulate enzyme kinetics and produce Lineweaver-Burk plots. The tutorial is intended for use in third- or fourth-year undergraduate biochemistry courses. (Contains 4 figures.)
