Which is not found on a membrane?
A. receptor tyrosine kinase
B. intracellular receptor
C. ligand-gated ion channel
D. G protein-coupled receptor

The intracellular receptor is the type of receptor not found on a membrane, as it is located within the cell. In contrast, receptor tyrosine kinases, ligand-gated ion channels, and G protein-coupled receptors are all membrane-bound proteins. Understanding the location of these proteins is crucial in cell signaling mechanisms. ;

The correct answer is B. intracellular receptor, as it is not located on the membrane but rather inside the cell. In contrast, receptor tyrosine kinases, ligand-gated ion channels, and G protein-coupled receptors are all found in the cell membrane. Understanding the locations of these receptors is essential in cell signaling mechanisms.
