IB Biology C1.1.10 Effect of enzymes on activation energy
Practise reading energy-profile graphs to show how enzymes alter activation energy without changing overall energy release.
How this is tested
- identify activation energy on reaction energy graphs with and without enzymes
- predict that adding a suitable enzyme lowers the activation energy peak
- draw or interpret catalysed curves with unchanged start and end energy levels
