IB Biology C2.2.7 Excitatory postsynaptic potential
Practise explaining how neurotransmitter binding generates an excitatory postsynaptic potential and can start a new impulse.
How this is tested
- explain how neurotransmitter diffuses across the cleft and binds to receptor proteins
- link receptor binding to ion entry and depolarisation of the postsynaptic membrane
- distinguish formation of a postsynaptic impulse from neurotransmitter removal
