Enzyme Active Site & Substrate Binding Simulation
Students test substrates against an enzyme active site, examining how both shape and chemical properties determine whether a substrate binds and why a near-fit still fails. It extends the lock-and-key idea into a fuller account of enzyme specificity. The full interactive is available to licensed Education Universe users.
Years 11–12, UndergraduateExplorer
Learning outcomes
- Explain enzyme specificity in terms of active site shape and chemistry.
- Explain why a substrate with a similar shape may still fail to bind.
- Describe the limits of the lock-and-key model.
Teaching guidance
Ask students to predict which substrates will bind and why before testing, then discuss the near-fit cases.
