Synaptic potentials are __________Blank potentials resulting from opening or closing __________Blank-gated ion channels.Multiple Choicelocal; chemicallyaction; voltageaction; chemically

What will trigger the opening of chemically gated ion channels?Multiple choice question.binding of neurotransmitter moleculeschanges in membrane potential

Select all that applyChoose the properties of voltage-gated channels.Multiple select question.They open and close in response to small voltage changes in the membrane potential.They allow most ions to pass through depending upon their concentration gradient.They open or close when a ligand binds to a receptor that is part of the ion channel.They are specific for the type of ion that passes through them.

Ion channels that respond to neurotransmitter molecules are described as gated.
