Study Notes

Key Terms in Enzymatic Reactions

  • Activation energy: The minimum energy required to initiate a chemical reaction, essential for overcoming the energy barrier for reactants.
  • Catalyst: A substance that accelerates a chemical reaction without being consumed, allowing for quicker reaction rates.

Enzymes

  • Enzyme: A specialized protein that acts as a biological catalyst, facilitating and speeding up chemical reactions within cells.
  • Substrate: The specific reactant molecule upon which an enzyme acts, ensuring the enzyme's specificity for its particular reaction.

Enzyme Structure and Function

  • Active site: A specific region of an enzyme where the substrate binds, enabling the conversion of substrate into products, crucial for enzyme functionality.
