Michaelis-Menten kinetics

noun, plural in form but singular or plural in construction

Mi·​chae·​lis-Men·​ten kinetics -ˈmen-tən- 

: the behavior of an enzyme-catalyzed reaction with a single substrate especially as exhibited by plotting the velocity of the reaction against the concentration of the substrate which yields a hyperbolic curve approaching a horizontal asymptote rather than yielding a straight line as in nonenzymatic reactions and which has an equation of the form where v is the velocity of the reaction, V is the asymptotic value of the velocity, K_m is the Michaelis constant, and s is the concentration of the substrate
