WebThe cell membrane is composed of a phospholipid bilayer and has many transmembrane proteins, including different types of channel proteins that serve as ion channels. The sodium/potassium pump requires energy in the form of adenosine triphosphate (ATP), so it is also referred to as an ATPase. WebNeurons communicate with muscle cells through a synapse, which is a specialized junction between the presynaptic neuron and the postsynaptic muscle cell. At the presynaptic terminal, the action potential triggers the release of …
