Both insulin and glucagon are peptide hormones that target liver cells.The responses of the target cells to these two hormones are exactly the opposite of each other.This information implies that

Question

Quizplus · Accepted Answer

Insulin and glucagon both bind to receptors on the cell membrane of liver cells, but they activate different signaling pathways inside the cell. Insulin activates a pathway that leads to glucose uptake and storage in the liver, while glucagon activates a pathway that stimulates glucose production and release from the liver. These different responses require different second messengers, which are molecules that transmit signals from the hormone receptor to the inside of the cell. Therefore, the best choice is B, which states that each of the two hormones uses a different second messenger.
