Question

Quizplus · Accepted Answer

Ligand-gated ion channels are involved in rapid responses of muscle cells and neurons. When the appropriate ligand binds to the receptor, the channel opens, allowing ions to flow through the membrane and rapidly change the membrane potential, leading to muscle contraction or neuronal signaling. G protein-coupled receptors and receptor kinases are more involved in slower, long-lasting responses. Intracellular receptors are located inside the cell and are not involved in the rapid response of muscle cells and neurons to external stimuli.
