Thank you!!!
Complete each sentence to assess your knowledge of neurotransmitter storage and release at a typical neuronal synapse, SNARE As action potentials propagate along a myelinated fiber, they jump from one node of Ranvier to the next and for this reason such propagation is called reuptake presynaptic Eventually, the action potential reaches the terminal of the neuron postsynaptic Depolarization in the terminat...

Neuronal cells on your taste buds initiate an action potential when they detect specific flavor molecules. Cell surface proteins that detect flavor molecules and initiate an action potential could be: Select one: a. potassium leak channels b. intracellularly ligand-gated sodium channels c. aquaporin channels d. mechanically gated channels e. extracellularly ligand-gated sodium channels

An inhibitory postsynaptic potential (IPSP) A- will cause the postsynaptic membrane potential to become more positive. B- is the result of voltage-gated sodium channels opening on the postsynaptic membrane. C- may result from positively charged ions entering the postsynaptic cell. D-will make it more difficult for the postsynpatic neuron to reach threshold.

Can someone please explain to me in detail how to answer this one? How could a neurotransmitter bind to a receptor on the post-synaptic membrane, open certain ion channels, and in the process cause an inhibitory post-synaptic potential? A. the neurotransmitter binds to a ligand-gated sodium channel B. the neurotransmitter binds to a signal transduction receptor C. the neurotransmitter binds to a ligand-gated chloride channel D. the neurotransmitter enters the post-synaptic cell, inhibiting it
