参考答案: C
本题详细解析: C
Choice C is correct because the sequence is in the right order. Insulin first needs to bind to the extracellular domain of the tyrosine kinase receptor to activate the kinase.
Choices A, B and D are incorrect because the sequence is in the wrong order. When specific ligands, such as insulin, activate the tyrosine kinase receptor, the phosphorylation of the intracellular domain occurs, which brings about further cascade events.
