Cell signaling is a fundamental pillar of medical biochemistry and pharmacology. This illustration clarifies the GPCR cell signaling pathway, depicting the transition from an inactive 7-transmembrane receptor to active G protein cell signaling. Trace how adenylyl cyclase and phospholipase C act as effector enzymes to produce second messengers in cell signaling, including cAMP, IP3, and DAG. Understanding the distinction between Gq, Gs, and Gi pathways is essential for predicting drug effects on the USMLE. High-contrast vector segments isolate the dissociation of the alpha subunit from the beta-gamma complex to make the molecular mechanics visually intuitive.
