You are a neuroscientist and have been provided a sample of a new snake venom. You test its effect on action at a synapse, and find that it increases the magnitude of the normal depolarizing excitatory response. The most likely explanation for this is that the venom is: O O O preventing the presynaptic action potential from arriving at the synapse. degrading the myelin sheath around the axon. acting to break down the neurotransmitter in the synaptic cleft. reducing the distance between neighbouring neurons. binding with the neurotransmitter receptors to interfere with neurotransmitter binding. blocking the release of the neurotransmitter from the vesicles. binding with the neurotransmitter receptors to mimic the action of the neurotransmitter. binding to hormone receptors and stimulating the release of androgens
