Curriculum Support

On Demand

20 mins


Host: Jamie Johnson - BSc (Hons), MSc, PGCE. Jamie is a Science teacher who is passionate about breaking down complex topics into digestible bites for students. 

Enzymes have multiple uses in science, from catalysing reactions in living organisms to use in industrial and domestic settings.

This lesson looks at enzymes as a biological catalyst, and their use in living organisms to aid digestion.

Safeguarding reminder:  We know that the safety of your child is of the utmost important. This is why we use Zoom's Webinar feature to provide our live classes, where by default, your child's webcam and microphone are disabled. 

Key takeaways:

  • Describe an enzyme as a biological catalyst, and describe what this means.
  • Define a polymer and monomer, with examples from human digestion.
  • Describe, with an example, the problems that can arise if enzymes are not present or don’t function.
