which of the following statements is true?
lonotropic channels contain a neurotransmitter binding site but lack an ion channel as part
of its structure
binding of a neurotransmitter to an ionotropic receptor always results in an excitatoty
postsynaptic potential (epsp)
metabotropic receptors open an ion channel through the action of a g protein
metabotropic receptors are a type of ligand-gated channel
lonotropic receptors open an ion channel through the action of a g protein

3)Metabotropic receptors open an ion channel through the action of a G protein

Explanation:

Postsynaptic inhibition and excitation are similar, or much the same. Neurotransmitters are getting attached to receptors and they are opening or closing ion channels that are in the cell and since that they are similar this statement is false.

Iigand-gated ion channels are type of membrane-bound receptors so this statement is also false.

 Binding neurotransmitters and metabotropic receptors can activate G-proteins. Then, the G-proteins interact with other channels or they can bind to some other protein.

answer: mannn ion even know fam

explanation: just try asking yoo teacher yo parents or just simply another sight

answer; i believe the correct answer to the above question is ( friction)
