IB Biology C2.2.5 Synapses as junctions
Practise explaining synapses as narrow junctions where chemical transmission carries impulses between neurons.
How this is tested
- distinguish presynaptic and postsynaptic membranes by channels, vesicles and receptors
- explain how neurotransmitter crosses the synaptic cleft to affect the next neuron
- interpret synapse diagrams and data on neurotransmitter concentration or removal
