CAIE IGCSE Biology EXTENDED 14.1.9 Events at a synapse
Practise sequencing neurotransmitter release, diffusion and receptor binding to explain how an impulse crosses a synapse.
How this is tested
- sequence release from vesicles, diffusion across the gap and binding to receptors
- describe neurotransmitter movement down a concentration gradient across the synaptic gap
- explain drug or disease effects using blocked receptors or fewer neurotransmitters released
