  • Michaelis-Menten Equation
    A mathematical model relating initial enzyme reaction rates to substrate concentration using key kinetic variables.
  • Initial Reaction Velocity
    The rate measured at the very start of an enzyme-catalyzed reaction before significant substrate depletion.
  • Substrate Concentration
    The amount of reactant available for the enzyme to convert, plotted on the x-axis in kinetics graphs.
  • Vmax
    The theoretical maximum rate achieved by an enzyme when substrate is abundant and all active sites are occupied.
  • Km
    A constant representing the substrate concentration at which the reaction rate is half of its maximum value.
  • Enzyme Kinetics
    The study of how reaction rates change in response to varying substrate concentrations and enzyme properties.
  • Rectangular Hyperbola
    A curve shape seen in enzyme kinetics plots, reflecting the relationship between reaction rate and substrate concentration.
  • Enzyme Kinetics Plot
    A graphical representation showing how initial reaction velocity varies with substrate concentration.
  • Y-Axis
    The vertical axis in kinetics plots, typically displaying initial reaction velocity.
  • X-Axis
    The horizontal axis in kinetics plots, typically displaying substrate concentration.
  • Kinetic Variables
    Quantities such as initial reaction velocity, substrate concentration, Vmax, and Km used in enzyme kinetics equations.
  • Mathematical Model
    A formal equation or system used to describe and predict enzyme-catalyzed reaction behaviors.
  • Enzyme-Catalyzed Reaction
    A chemical process accelerated by a biological catalyst, whose rate is analyzed using kinetic equations.
