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

Synaptic potentials are due to the opening of what type of channels?Multiple ChoiceVoltage-gated ion channelsChemically-gated ion channels

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.

Within a chemical synapse, the receptors Blank______.Multiple choice question.are only responsive to changes in voltageare always degraded by enzymes in order disable thembind to a variety of different ligandsbind to very specific ligands

In response to an action potential, voltage-gated calcium channels Blank______ in the presynaptic cell's axon terminal.Multiple choice question.closeopen

Binding of chemical signals to receptors, changes in membrane voltage, mechanical stimulation, temperature changes and spontaneous membrane changes can all cause Blank______ potentials.Multiple choice question.triggergradedresting membrane
