Enzymes

• Active sites have specific shapes to fit their corresponding substrates.
• Substrates must be able to reach the active site through diffusion or transport mechanisms.
• Enzymes bind to their substrates in a lock-and-key fashion, forming an enzyme-substrate complex through interactions such as hydrogen bonds, ionic bonds, and hydrophobic interactions.
• Enzymes act as highly selective catalysts for specific biochemical reactions due to their three-dimensional structure.
• The shape of the active site is complementary to that of the substrate, allowing it to fit snugly into place.
• The shape of the active site is complementary to that of the substrate molecule.
• The active site contains amino acid residues with chemical groups capable of interacting with the substrate.
