Hormones that are proteins or protein derivatives

Question

Quizplus · Accepted Answer

Hormones that are proteins or protein derivatives act through a second messenger called cyclic AMP, which is involved in altering protein synthesis. These hormones cannot diffuse through the cell membrane to react with receptors inside the cell, so they require a second messenger system to transmit their message inside the cell. Administering these hormones orally is not effective because they are broken down by enzymes in the digestive system.
