  2. Enzyme kinetics - Wikipedia

    en.wikipedia.org/wiki/Enzyme_kinetics

    The substrate concentration midway between these two limiting cases is denoted by K M. Thus, K M is the substrate concentration at which the reaction velocity is half of the maximum velocity. [2] The two important properties of enzyme kinetics are how easily the enzyme can be saturated with a substrate, and the maximum rate it can achieve.

  3. Michaelis–Menten kinetics - Wikipedia

    en.wikipedia.org/wiki/Michaelis–Menten_kinetics

    When studying urease at about the same time as Michaelis and Menten were studying invertase, Donald Van Slyke and G. E. Cullen [29] made essentially the opposite assumption, treating the first step not as an equilibrium but as an irreversible second-order reaction with rate constant +. As their approach is never used today it is sufficient to ...

    b) The straight portion of the graph for substrate concentration over time is indicative of a zero-order dependence on substrate for most of the reaction, but the curve at low [A] is indicative of a change to (in this case) a first-order dependence on [A].

  6. Plateau principle - Wikipedia

    en.wikipedia.org/wiki/Plateau_Principle

    Half-life has units of time, and the elimination rate constant has units of 1/time, e.g., per hour or per day. An equation can be used to forecast the concentration of a compound at any future time when the fractional degration rate and steady state concentration are known:
