Spastic paralysis (resulting from the failure of muscles to relax), induced by the neurotoxin strychnine, occurs when this poison blocks the binding of:
the excitatory neurotransmitter acetylcholine to post-synaptic sodium channels
the excitatory neurotransmitter glutamate to post-synaptic calcium channels
the excitatory neurotransmitter serotonin to post-synaptic potassium channels
the inhibitory neurotransmitter glycine to post-synaptic chloride channels
the inhibitory neurotransmitter melatonin to post-synaptic bicarbonate channels
Classify the following neurotransmitters as excitatory or inhibitory:
Acetylcholine
Serotonin
GABA
Norepinephrine

GABA binds to GABA receptors and opensligand-gated Cl–channels. However, chronic consumption of alcoholmakes the GABA receptor less sensitive to both alcohol and GABA,which increases alcohol dependence as well as alcohol withdrawalsymptoms, such as anxiety, tremors, and insomnia. Benzodiazepinesenhance the binding of GABA molecules to their receptors and thus aresometimes used to treat people with alcohol withdrawal symptoms. Forsynapses involving GABA, predict the effect of alcohol on the postsynaptic membranes; compare the effect of chronic alcohol consumption onthe postsynaptic membranes in these synapses; and predict the effect ofbenzodiazepine treatment on the degree of polarization of postsynapticmembranes in people who are experiencing alcohol withdrawalsymptoms.arrow_forward
