IB Biology C1.1.8 Effects on enzyme activity
Practise interpreting graphs and experiments on how temperature, pH and concentration affect enzyme activity and reaction rate.
How this is tested
- interpret enzyme activity graphs for temperature, pH and substrate concentration changes
- explain rate changes using collisions, denaturation and active-site occupancy
- compare experimental outcomes where controlled conditions alter enzyme activity
