IB Biology C1.1.2 Role in metabolism
Practise defining metabolism and explaining how enzymes control linked reactions in pathways by catalysing each step and reducing activation energy.
How this is tested
- define metabolism as the total enzyme-catalysed reactions in a cell or organism
- explain why each step in a metabolic pathway depends on a specific enzyme
- link enzyme production or inhibition to control of pathway progress
