The major mechanisms for neurotransmitter inactivation are (a) absorption into non-gated ion channels and diffusion into glia. (b) reuptake and enzyme degradation. (c) enzyme degradation and influx through neurotransmitter-gated ion channels. (d) diffusion across the synapse and binding to post-synaptic receptors. Example test question

Textrodotoxin (TTX) is a chemical used experimentally to block the flow of sodium through voltage‑gated Na+ channels. In such an experiment, with voltage-gated Na+ channels completely blocked, one would expect to observe cells that (a) have prolonged action potentials. (b) propagate action potentials more slowly. (c) fail to exhibit action potentials when depolarized to threshold. (d) have resting potentials of zero mV. (e) propagate action potentials non-decrementally to the axon terminal.
