The role of Ca2+ ions in the release of neurotransmitter: a) Inhibit release of neurotransmitter b) Cause releasing of neurotransmitter from axon terminal c) Attach to post synaptic receptors d) Open Na+ channels e) Close potassium channel
B) causes release of neurotransmitter because it allows the vesicles carrying the Neurotransmitters to fuse with the presynaptic neuron’s axon terminal membrane and release the neurotransmitters in an exocytotic manner
