2. What is downstream processing?

  • Having to repeat a chemical process more than once to ensure that all the products have reacted.
  • The separation and purification of any product of large scale fermentors.
  • An aseptic technique.
  • Feeding reactants back into the mixture.
  • Adding enzymes to a reaction mixture.

3. Which of these is not an advantage of immobilising enzymes

  • Enzymes are immediatley available for reuse.
  • They are more stable.
  • They allow for a continuous process
  • Requires additional time,equipment and materials
  • Processing costs are low.

4. Which of these is not a method for immobilising enzymes

  • Covalent bonding
  • Entrapment
  • Absorbtion
  • Adsorption
  • Membrane separation

5. Which of these is a disadvantage for Entrapment

  • Reaction rates are slower.
  • Binding is very strong.
  • Bonding forces are not very strong so leakage can occur.
  • It does not immobilise a large quantity of enzymes.
  • The active site of the enzyme is changed.
