Could I rephrase the summary?
Enzyme kinetics is the study of the rates of chemical reactions that are catalysed by enzymes. Enzymes are molecules that manipulate other molecules — the enzymes' substrates. These target molecules bind to an enzyme's active site and are transformed into products in a series of steps known as the enzymatic mechanism. The study of an enzyme's kinetics provides insights into this catalytic mechanism, as well as the role of the enzyme in metabolism, how its activity is controlled in the cell and how drugs and poisons may inhibit its activity. Knowledge of the enzyme's structure is helpful in interpreting the kinetic data.
