The answer is A. The insulin, like many hormones binds to cells through receptors found on the cell membrane
Answer:
Explanation:
Protein deeply embedded in the bilayer are called integral membrane proteins. Most of this integral membrane proteins span the whole bilayer and they are called Transmembrane protein.
Because many molecules and ions can not pass through the hydrophobic core of the cell membrane they need a carrier mediated transport to go in and out of the cell. Transmembrane protein serves as channels, receptors (hormones, growth factors, neurotransmitter), tissue specific antigens, ion channels, membrane based enzymes etc that moves in and out of the cell.
