The neurotransmitter acetylcholine (ACh) causes the rapid contraction of skeletal muscle and the slower relaxation of cardiac muscle. Which one of the following is the most likely explanation for this difference? A. ACh activates a GPCR pathway in cardiac muscle and an ion channel coupled receptor in skeletal muscle. B. ACh activates an ion channel coupled receptor in cardiac muscle and a GPCR pathway in cardiac muscle. C. ACh is permeable through the plasma membrane of skeletal muscle cells but...
