IB Biology C1.1.1 Enzymes as catalysts
Practise explaining how enzymes catalyse metabolic and digestive reactions by binding substrates, forming complexes and lowering activation energy.
How this is tested
- outline enzyme action from substrate collision to enzyme-substrate complex formation
- explain how lowering activation energy increases the rate of biological reactions
- apply enzyme catalysis to digestion using named pancreatic enzymes when given
