  • Enzyme-Substrate Complex
    Intermediate formed when an enzyme binds to its substrate, appearing at a local minimum energy point in a reaction.
  • Intermediate
    Transient molecule in a multi-step reaction, existing briefly at a local minimum energy point before further transformation.
  • Transition State
    High-energy configuration in a reaction, represented by a local maximum peak on an energy diagram.
  • Activation Energy
    Energy barrier that must be overcome for a reaction to proceed, lowered by enzyme stabilization of the transition state.
  • Non Covalent Forces
    Weak interactions, such as hydrogen and ionic bonds, that mediate most enzyme-substrate complex formation.
  • Hydrogen Bond
    Type of non covalent interaction contributing to the stabilization of enzyme-substrate complexes.
  • Ionic Bond
    Electrostatic attraction between charged groups, often involved in enzyme-substrate complex stabilization.
  • Catalysis
    Process by which enzymes accelerate chemical reactions, primarily through stabilization of the transition state.
  • Binding Energy
    Energy released when non covalent interactions form in the enzyme-substrate complex, used to stabilize the transition state.
  • Active Site
    Region of an enzyme where substrate binding and transition state stabilization occur.
  • Product
    Molecule generated from substrate transformation during an enzyme-catalyzed reaction.
  • Substrate
    Molecule that interacts with an enzyme, forming a complex and undergoing conversion to a product.
  • Energy Diagram
    Graphical representation of energy changes during a reaction, illustrating intermediates and transition states.
  • Uncatalyzed Reaction
    Chemical process occurring without enzyme involvement, characterized by a higher activation energy.
  • Catalyzed Reaction
    Chemical process facilitated by an enzyme, resulting in a lower activation energy and faster product formation.
