Which of the following hormones must deliver its signal using the "second-messenger" mechanism?

Question

Quizplus · Accepted Answer

Vasopressin utilizes the second-messenger mechanism to deliver its signal. This means that vasopressin binds to a receptor on the membrane of a cell and activates a signaling cascade that ultimately leads to the production of a second messenger molecule (usually cyclic AMP or calcium ions) within the cell. This second messenger then goes on to activate other signaling pathways within the cell, leading to the physiological response that vasopressin is associated with. Estradiol, testosterone, progesterone, and androsterone do not use this mechanism to deliver their signals.
