  • Show a graphic of the lock-and-key fit of enzymes for background information
  • Make sure the class understands the breakdown of lactase to galactose and glucose, so they know why they are testing for glucose in this lab
Classroom Considerations

  • Need a heat source to boil water for 30 minutes (can do prior to lab)

  • Additional resources are available
  • Provides clear instructions to complete the lab
  • Materials are easy to obtain

  • No background information on enzymes or pictures of enzyme-substrate models available
