C)Specialized phospholipids within the membrane
D)Nucleic acids

Question

Quizplus · Accepted Answer

Receptors for intercellular messengers are most commonly integral membrane proteins. These proteins are embedded within the cell membrane and contain binding sites that recognize specific messenger molecules. When a messenger molecule binds to its receptor, it triggers a cellular response. Peripheral membrane proteins and specialized phospholipids within the membrane can also play a role in cellular signaling, but they are not typically the primary receptors for intercellular messengers. Nucleic acids are not involved in cellular signaling in this way.
