Which correctly describes an action of the hormone insulin?

Question

Quizplus · Accepted Answer

Insulin is responsible for increasing the uptake and utilization of glucose by muscle and adipose tissue cells. It does this by binding to insulin receptors on these cells, which triggers the movement of glucose transporter proteins (GLUT4) to the cell surface, allowing glucose to enter the cell and be used for energy or stored as glycogen.

All the other options are incorrect:

B) Insulin is not required for the uptake and utilization of glucose by nervous tissue. Nervous tissue can use glucose without insulin.
C) Insulin does not decrease the uptake of amino acids by muscle cells. In fact, insulin increases the uptake of amino acids into muscle cells, which is important for muscle growth and repair.
D) Insulin does not stimulate the breakdown of glycogen in the liver. Instead, insulin stimulates the synthesis of glycogen in the liver, which helps to lower blood glucose levels.
E) Insulin does not inhibit the action of lipoprotein lipase in the capillaries of adipose tissue. Instead, insulin stimulates the activity of lipoprotein lipase, which breaks down triglycerides in circulating lipoproteins, allowing the release of free fatty acids for storage in adipose tissue.
