  • Lineweaver-Burk Plot
    Graphical representation of enzyme kinetics using reciprocals, transforming a hyperbolic curve into a straight line for easier analysis.
  • Lineweaver-Burk Equation
    Linearized form of enzyme kinetics, derived by inverting and rearranging the Michaelis-Menten equation to fit y = mx + b.
  • Michaelis-Menten Equation
    Original enzyme kinetics formula describing a hyperbolic relationship between reaction velocity and substrate concentration.
  • Reciprocal
    Mathematical inversion of a value, used in Lineweaver-Burk plots to linearize enzyme kinetic data.
  • Initial Reaction Velocity
    Rate of product formation at the start of an enzyme-catalyzed reaction, plotted as a reciprocal on the y-axis.
  • Substrate Concentration
    Amount of reactant present, plotted as a reciprocal on the x-axis in Lineweaver-Burk plots.
  • Slope
    Ratio of Michaelis constant to maximum velocity, indicating how enzyme efficiency changes with substrate concentration.
  • Y-Intercept
    Point where the line crosses the y-axis, revealing the reciprocal of maximum velocity in enzyme kinetics.
  • X-Intercept
    Point where the line crosses the x-axis, representing the negative reciprocal of the Michaelis constant.
  • Maximum Velocity
    Theoretical highest rate of an enzyme-catalyzed reaction, determined from the y-intercept of the plot.
  • Michaelis Constant
    Substrate concentration at which reaction velocity is half-maximal, derived from the x-intercept.
  • Double Reciprocal Plot
    Alternative name for Lineweaver-Burk plot, emphasizing the use of reciprocals for both axes.
  • Rectangular Hyperbola
    Shape of the Michaelis-Menten plot, contrasting with the straight line of the Lineweaver-Burk plot.
  • Enzyme Kinetics
    Study of reaction rates and mechanisms in enzyme-catalyzed processes, often visualized with Lineweaver-Burk plots.
  • Equation of a Line
    Mathematical format y = mx + b, used to interpret the linear relationship in Lineweaver-Burk plots.
