Define Catalyst
  • Denature is when an enzyme stops functioning due to high heat.
  • Enzymes are macromolecular biological catalysts. Enzymes accelerate chemical reactions.
  • Primary structure is important because the order of amino acids determine where the polypeptide chain will fold based on each acids characteristics, which affects all other levels.
  • A catalyst is a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change.
How many different types of amino acids are there?
  • There are 20 types of amino acids.
  • The name of an enzyme typically ends with "ase".
  • Pepsin in an enzyme active in the stomach.
  • Amino Acids are protein's monomers.
Define Enzyme
  • Enzymes affect the reactions in living cells by lowering the activation energy of the reaction.
  • Denature is when an enzyme stops functioning due to high heat.
  • Enzymes are macromolecular biological catalysts. Enzymes accelerate chemical reactions.
  • Enzymes are highly specific catalysts. An enzyme and its substrate both have very specific shapes designed to fit together.
List and describe the four levels of protein structure.
  • Primary structure is important because the order of amino acids determine where the polypeptide chain will fold based on each acids characteristics, which affects all other levels.
  • Competitive inhibitors bind to the enzyme at the active site, preventing substrates from bonding. Non-competitive inhibitors bind to the enzyme not at the active site, therefore not preventing substrates from bonding.
  • Protein is a major source of energy and are involved in the creation of some hormones. They transport and store molecules.
  • 1. Primary - The order of amino acids2. Secondary - The regular pattern of coils or folds of the polypeptide chain3. Tertiary - The overall three dimensional shape of polypeptide chain4. Quaternary - The association of two or more polypeptide subunits
What is an enzyme inhibitor?
  • Enzymes are highly specific catalysts. An enzyme and its substrate both have very specific shapes designed to fit together.
  • An enzyme inhibitor is a molecule that binds to an enzyme and decreases its activity.
  • A disulfide bridge is a covalent bond derived from two thiol groups.
Which monomer is linked together to form proteins?
  • There are 20 types of amino acids.
  • Pepsin in an enzyme active in the stomach.
  • A proteins shape determines its function.
  • Amino Acids are protein's monomers.
Which enzyme would be most active in the stomach?
  • Amino Acids are protein's monomers.
  • Protein is a major source of energy and are involved in the creation of some hormones. They transport and store molecules.
  • The name of an enzyme typically ends with "ase".
  • Pepsin in an enzyme active in the stomach.
Define Denature
  • Enzymes are macromolecular biological catalysts. Enzymes accelerate chemical reactions.
  • Denature is when an enzyme stops functioning due to high heat.
  • A disulfide bridge is a covalent bond derived from two thiol groups.
  • A catalyst is a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change.
How do enzymes affect the reactions in living cells?
  • The name of an enzyme typically ends with "ase".
  • Enzymes are macromolecular biological catalysts. Enzymes accelerate chemical reactions.
  • Enzymes affect the reactions in living cells by lowering the activation energy of the reaction.
  • Enzymes are highly specific catalysts. An enzyme and its substrate both have very specific shapes designed to fit together.
What are the main functions of proteins found in organisms?
  • Protein is a major source of energy and are involved in the creation of some hormones. They transport and store molecules.
  • Competitive inhibitors bind to the enzyme at the active site, preventing substrates from bonding. Non-competitive inhibitors bind to the enzyme not at the active site, therefore not preventing substrates from bonding.
  • After an enzyme has broken up a protein it returns to its original shape and will work on another molecule or substrate.
  • Proteins are composed of hydrogen, oxygen, nitrogen, and carbon. Some proteins also contain sulfur.
