Quizplus · Accepted Answer

The effects of acetylcholine on the postsynaptic ion channel are mainly due to protein conformational changes. Acetylcholine binds to receptors on the postsynaptic membrane, causing a change in the conformation of the protein that opens the ion channel. This allows ions, such as sodium (Na+) or potassium (K+), to flow in or out of the cell, leading to changes in the membrane potential and the transmission of neural signals. None of the other choices are directly related to the effects of acetylcholine on the postsynaptic ion channel.
