Nicotinic acetylcholine receptors allow both sodium and potassium to flow across the cell membrane when the receptors are activated. Which statement is true about the flow of ions through nicotinic receptors? Potassium only flows through an open nicotinic receptor only when there is no sodium present. More sodium ions pass through an open nicotinic receptor than pass potassium ions. An equal number of sodium and potassium ions pass through an open nicotinic receptor. More potassium ions pass through an open nicotinic receptor than pass sodium ions.

A patient has been bitten by a snake. The snake venom contains a toxin that specifically targets nicotinic acetylcholine receptors (nAChRs). Immediately after the venom enters the bloodstream the patient begins suffering from paralysis at their extremities. Question: which of the following statements best describes what is happening and why? O The snake venom competitively inhibits nAChRs, preventing acetylcholine from opening an ion channel that depolarizes the postsynaptic cell. O The toxin activates metabotropic receptors. G-proteins then activate CAMP that, in turn, acts upon second messenger pathways. O The toxin acts via presynaptic inhibition to prevent acetylcholine from entering the synaptic cleft. O All of the above.
