Question

Quizplus · Accepted Answer

Ligand-gated channels allow ions to move across the plasma membrane. They open or close in response to the binding of a specific molecule, such as a neurotransmitter or hormone. When the ligand binds to the receptor, a conformational change occurs that allows ions to pass through the channel, which can generate an electrical signal in cells like neurons or muscle cells.
