Initial Velocity definitions

Control buttons has been changed to "navigation" mode.
1/15
  • Initial Velocity
    Fastest reaction rate observed at the very start, when substrate is highest and product is negligible, minimizing reverse reactions.
  • Enzyme Kinetics Plot
    Graph showing initial reaction rates versus substrate concentrations, used to analyze enzyme behavior without time as a variable.
  • Substrate Concentration
    Amount of reactant present at the start, directly influencing the speed of enzyme-catalyzed reactions.
  • Product Concentration
    Amount of reaction output measured over time, used to determine reaction progress and equilibrium.
  • Reverse Reaction
    Process where product converts back to substrate, becoming significant as product accumulates.
  • Maximum Velocity
    Highest possible rate an enzyme can approach, observed when substrate saturates the enzyme.
  • Equilibrium
    State where forward and reverse reaction rates are equal, causing product concentration to stabilize.
  • Saturation
    Condition where all enzyme active sites are occupied, so increasing substrate no longer boosts reaction rate.
  • Data Point
    Individual measurement from a separate experiment, representing initial velocity at a specific substrate concentration.
  • Temperature
    Environmental factor kept constant in experiments to ensure reliable comparison of reaction rates.
  • pH
    Chemical property maintained across experiments to prevent variation in enzyme activity.
  • Enzyme Concentration
    Amount of catalyst present, controlled to ensure consistent reaction conditions in kinetic studies.
  • Slope
    Mathematical representation of reaction rate, calculated as change in product concentration over change in time.
  • Test Tube
    Laboratory vessel used for separate experiments, each with distinct substrate concentrations for kinetic analysis.
  • Curve of Best Fit
    Smooth line drawn through data points on a kinetics plot, illustrating the relationship between substrate and initial velocity.
