This provides you with a larger flexibility in conducting the experiments, allowing you to change parameters such as substrate concentrations, enzyme concentrations, temperature or pH and receive the corresponding results.A large number of enzymatic reactions can be adequately described by Michaelis-Menten kinetics. The Michaelis-Menten equation represents a rectangular hyperbola, with a y-asymptote at the V max value. However, in other cases, more complex kinetic models are required to explain the observed data. Atypical kinetic profiles are believed to arise ...theory.labster.com

Abstract. Enzyme kinetics is arguably the most time and cost effective way to study enzymes. It is the primary way to study enzyme catalysis, because no other approach allows one to test whether a chemically or spectrophotometrically detected intermediate is formed and turned over on the catalytic timescale.
