The postsynaptic membrane contains specialized proteins that function primarily as

A. Voltage-gated ion channels
B. Ligand-gated ion channels
✓
C. Mechanically-gated ion channels
D. Leak channels

📝 Explanation

Neurotransmitters bind to specific ligand-gated receptors on the postsynaptic membrane, which undergo a conformational change to open ion channels and generate graded potentials.
