Question

Quizplus · Accepted Answer

Angiotensin II acts on its target cell via a second messenger system involving the G protein-coupled receptors and the phospholipase C pathway, ultimately leading to an increase in intracellular calcium levels and activation of downstream signaling pathways. Thyroxine, estrogen, testosterone, and aldosterone all act through direct binding to intracellular receptors in the target cell nucleus.
