Solution:Concept- By encouraging the liver to absorb glucose from the blood, insulin controls the metabolism of carbs, proteins, and lipids. Glycogen is created from the ingested glucose and is then stored until it is needed.
The cell organelle known as the plasma membrane is a phospholipid bilayer that contains several transporter proteins. The many proteins that are incorporated in the phospholipid bilayer can pass through and out of the layer that transports chemicals into and out of the cells.
A glycoprotein receptor on the surface of the plasma membrane's carrier protein is where insulin binds. These receptors have alpha-subunits that bind the insulin-producing hormone and are activated by tyrosine protein kinase. Depending on the gradient of the material's concentration, this carrier protein causes the transport of bound molecules from the cell's outside to its interior. The insulin hormone moves the liver's glycogen reserves through the plasma membrane's bilayer whenever a cell organelle needs energy.
As a result, the plasma membrane is where insulin works.
Hence, the correct answer is option 3).
