What happens in an axon terminal when an action potential arrives at the presynaptic membrane?
sodium ions diffuse in
sodium ions diffuse out
calcium ions diffuse in
calcium ions diffuse out
What happens when calcium ions diffuse into an axon terminal?
vesicles release neurotransmitter by exocytosis
voltage-gated sodium channels open
voltage-gated sodium channels close
neurotransmitter is pumped from the post-synaptic membrane
How does neurotransmitter cross the synaptic cleft?
exocytosis
simple diffusion
carrier mediated transport
osmosis
What causes sodium ion channels on the postsynaptic membrane to open?
arrival of an action potential at the channel
enzymatic digestion of the neurotransmitter bound to the channel
binding of the neurotransmitter to the channel itself
binding of calcium ions to the channel itself
What causes sodium ion channels on the postsynaptic membrane to close?
arrival of an action potential at the channel
enzymatic digestion of the neurotransmitter bound to the channel
binding of the neurotransmitter to the channel itself
binding of calcium ions to the channel itself
