IB Biology HL C1.2.1 ATP distributes energy

IB Biology syllabusFirst assessment 2025
Practise explaining how ATP stores, releases and transfers usable energy for cell processes such as active transport in neurons.
How this is tested
- explain why ATP is a useful short-term energy store within cells
- link ATP breakdown to energy release for sodium-potassium pumps in neurons
- interpret respiration questions where energy from compounds is captured as ATP
