Homework Answers
c. allow calcium to rush into the cell, causing neurotransmitter release.
Substances move into and out of the cell by means of transport vesicles. Exocytosis is the transport of substances or molecules through transport vesicles that cannot pass through the cell membrane. For example, the neurotransmitters present within the synaptic vesicles are released out by exocytosis. This sac like structure is formed from the layer of cell membrane.

If necessary, refer to Animation: Chemical Synapses. When an action potential reaches the axon terminal: sodium ions are released from the axon terminal, enter the cell body of the postsynaptic neuron through its sodium channels, and may initiate an action potential in that neuron. neurotransmitter molecules are released from the axon terminal and bind to receptors on the postsynaptic neuron, causing either an inhibitory hyperpolarization or an excitatory depolarization. neurotransmitter molecules are released from the axon terminal, bind to and...
