Question

HOMEWORK 10,HELP ME1

When an action potential depolarizes the
axon terminal, calcium enters into the
axon terminal through voltage-gated
calcium channels to: (one correct
statement)
Select one:
O a. trigger the synthesis of
neurotransmitter.
O b. trigger the opening of postsynaptic
voltage-gated ion channels.
O c. trigger exocytosis of
neurotransmitter.
O d. trigger endocytosis of synaptic
vesicles.

Expert Solution

Step 1

Neurotransmitters are chemical messengers for transmitting neural information. Neurotransmitters are synthesized by neurons and are stored in vesicles in the axon terminal.

Endocytosis means the gathering of something into the vesicles.

Exocytosis is the removal of something from vesicles.
