The chemicals released by the presynaptic neuron are released by:
cell rupture (break)
exocytosis
the actions of sodium on the cell membrane
endocytosis
Solution
The chemicals released by the presynaptic neuron are released by exocytosis.
Here's a step-by-step explanation:
-
The presynaptic neuron generates an electrical signal called an action potential, which travels down the neuron's axon.
-
When the action potential reaches the axon terminal (the end of the neuron), it triggers the opening of voltage-gated calcium channels.
-
The influx of calcium ions causes vesicles (small, membrane-bound compartments) filled with neurotransmitters (the chemicals) to move to the cell membrane.
-
The vesicles then fuse with the cell membrane, a process known as exocytosis.
-
The neurotransmitters are released into the synaptic cleft (the gap between the presynaptic and postsynaptic neurons).
-
The neurotransmitters can then bind to receptors on the postsynaptic neuron, transmitting the signal across the synapse.
So, the correct answer is exocytosis.
