Chap 4 Enzymes

• Enzymes

  Proteins that function as biological catalysts, catalysing or speeding up the rate of chemical reactions, and remain chemically unchanged at the end of the reaction
• Enzymes are catalysts found in living organisms
• Enzymes are biological in origin. They are made of protein .
• A substance that can speed up a chemical reaction without itself being chemically changed at the end of the reaction
• Proteins are made up of amino acid building blocks- Perform a variety of functions in the body, including acting as enzymes, hormones, and antibodies- Have a complex structure, with a unique sequence of amino acids determining the function of the proteinEnzymes are always made of proteins, never carbohydrates.
• enzymes usually have ase at the back
• enzyme is like a lock and the substrate is the key
