Worksheets and lesson ideas to challenge students aged 11 to 16 to think hard about enzymes (GCSE and Key Stage 3)
One of the best ways to help students understand enzyme action is to build Plasticine models of enzymes breaking down (or building up) substrate molecules. Students can modify the models to show denaturation and the effects of temperature, inhibitors and pH. If possible, ask students to film their models and add annotations to help them consider the dynamic nature of enzyme action. The Protein Data Bank provides some beautiful structures of enzymes.
Factors that affect enzyme action
GCSE activity for students to apply their knowledge of enzymes. Students work in pairs to apply their understanding of factors that affect enzymes. They will need to consider pH, temperature and enzyme specificity. This activity assesses and consolidates learning by asking students to apply their knowledge to novel situations. (PDF)
