An introductory AS Biology lesson on enzymes as biological catalysts. It sets out the unit objectives, links back to digestive enzymes students already know, and explains how enzymes work through the lock and key idea and activation energy before looking at the factors that affect the rate of reaction.
What this presentation covers
- enzymes as globular proteins and biological catalysts
- amylase and starch as an example
- how enzymes work: substrate, active site and product
- the lock and key model
- activation energy
- factors affecting rate, including substrate concentration
