CHAPTER 24 Plasma Membrane Receptors Cells use about 20 different families of receptor proteins to detect and respond to the myriad of incoming chemical and physical stimuli (Appendix 24-1). Most receptors are plasma membrane proteins that interact with chemical ligands or are stimulated by physical events such as light absorption. A few chemical stimuli, including steroid hormones and the gas nitric oxide, cross the plasma membrane and bind receptors inside the cell. Figure 24-1 sixteen classes of receptors with signal transduction mechanisms.
1 Glucagon binds its receptor in the plasma membrane of target cells (e.g. hepatocytes). 2  Bound receptor interacts with and, through a set of G proteins, turns on adenylate cyclase, which is also an integral membrane protein.ell surface receptors are integral membrane proteins and, as such, have regions that contribute to three basic domains: 1  Extracellular domains: Some of the residues exposed to the outside of the cell interact with and bind the hormone-another term for these regions is the ligand-binding domain.
