  • Q10
    Heroin is a powerful painkiller. Suggest how heroin affects the transmission across the synapses to reduce the feeling of pain.
    The heroin neurotransmitter causes more electrical impulses to be stimulated.
    Heroin increases the release of neurotransmitters.
    Heroin causes more receptors to be available for the neurotransmitter.
    Heroin reduces the release of neurotransmitters.
