  • Enzyme Kinetics
    Study of how substrate concentration influences the speed of enzyme-catalyzed reactions, revealing enzyme efficiency.
  • Substrate Concentration
    Amount of reactant available for enzyme binding, directly affecting reaction speed and rate-limiting factors.
  • Reaction Velocity
    Speed at which product forms in an enzyme-catalyzed reaction, often measured before any product accumulates.
  • Vmax
    Maximum reaction speed achieved when all enzyme molecules are saturated with substrate.
  • Km
    Substrate concentration required to reach half of the maximum reaction speed, reflecting enzyme-substrate binding strength.
  • Michaelis Constant
    Value indicating how much substrate is needed for an enzyme to operate at half its top speed; lower values mean tighter binding.
  • Turnover Number
    Number of substrate molecules converted to product per enzyme molecule per unit time under saturated conditions.
  • Rate Limiting Factor
    Component, either substrate or enzyme, that restricts how fast a reaction can proceed under specific conditions.
  • Enzyme Saturation
    State where all enzyme active sites are occupied by substrate, causing reaction speed to plateau at its maximum.
  • Enzyme Efficiency
    Measure of how effectively an enzyme converts substrate to product, influenced by both Vmax and Km.
  • Enzyme Availability
    Amount of enzyme present to catalyze reactions, which can become the limiting factor at high substrate levels.
  • Substrate Binding
    Interaction between enzyme and reactant, determining how tightly and efficiently the enzyme can catalyze the reaction.
  • Product Formation
    Creation of new molecules as a result of enzyme-catalyzed transformation of substrates.
  • Collision Frequency
    Rate at which enzyme and substrate molecules encounter each other, influencing the overall reaction speed.
  • Saturation Point
    Condition where increasing substrate concentration no longer increases reaction speed due to all enzymes being occupied.
