WebStimulants and depressants affect the synapses between neurones in the nervous system: stimulants cause more neurotransmitter molecules to diffuse across the synapse depressants stop the next neurone sending nerve impulses – they bind to the receptor molecules it needs to respond to the neurotransmitter molecules. Tobacco and Smoking WebThey do this in one of three ways. Neurotransmitters: Fade away (a process called diffusion). Are reabsorbed and reused by the nerve cell that released it (a process called reuptake). Are broken down by enzymes within the synapse so it can’t be recognized or bind to the receptor cell (a process called degradation). implementation of sdts
