What is the MOST IMPORTANT factor determining whether a ligand-gated ion channel is inhibitory or excitatory?

What is the MOST IMPORTANT factor determining whether a ligand-gated ion channel is inhibitory or excitatory?

1 point

ligand is a small molecular neurotransmitter or a neuropeptide

whether the

ligand is an amino acid or a biogenic amine

whether the

permeant ion’s reversal potential is positive (less polarized) or negative

(more polarized) relative to the resting membrane potential

whether the

permeant ion is positively or negatively charged

whether the

ligand-binding to the receptor increases cytoplasmic cAMP or cGMP

whether the

permeant ion’s reversal potential is less negative (less polarized) or more

negative (more polarized) relative to action potential threshold

whether the

ligand-binding to the receptor decreases cytoplasmic cAMP or cGMP
