Homework Answers
When the neurotransmitter acetylcholine binds to receptors on a postsynaptic membrane, it results in depolarization by allowing Na+ ions to influx the cell, followed by repolarization when Na+ ion gates open, allowing it to exit the cell membrane.
If you have any queries, kindly comment before giving a thumbs up. Thank you.

In its resting state, the membrane surrounding a neuron is
permeable to potassium ions but only slightly permeable to sodium
ions. Thus, positive K ions can flow through the membrane in an
attempt to equalize K concentration, but Na ions cannot as quickly.
This leads to an excess of Na ions outside of the cell. If the
space outside the cell is defined as zero electric potential, then
the electric potential of the interior of the cell is negative.
This...

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...

INFORMATION ABOUT IMAGE G FOR QUESTIONS 12-15:
GABAB receptors (GABABRs) are
G-protein-coupled receptors that can be found on both pre- and
postsynaptic neurons. When they are activated by GABA, they can
have a range of effects. For the synapse you are studying in the
following questions, the effects of GABABRs are
indicated in IMAGE G.
You are doing a series of experiments in which you are recording
from the pre- and postsynaptic cell at a synapse. The experiments
