A ligand binds to the extracellular portion of a receptor. Another ligand binds to an identical half of the same receptor. When this happens, the two halves come together and the intracellular portion adds phosphates from ATP to tyrosine amino acids it the receptor structure. This passage describes what kind of receptor? Select one: a. A G-protein coupled receptor b. A receptor tyrosine kinase c. A receptor tyrosine phosphatase d. A ligand-gated kinase channel
