Quizplus · Accepted Answer

Receptor tyrosine kinases (RTKs) undergo autophosphorylation on tyrosine residues upon ligand binding, leading to kinase activation and downstream signaling.

Answer: L
 Adenylate cyclase (AC) is activated by G protein-coupled receptors (GPCRs) such as the beta-adrenergic receptor, resulting in the production of cyclic AMP (cAMP). This pathway does not involve autophosphorylation.

Note: None of the other answer choices accurately fit the given criteria.
