Question

Which one is for cell-cell adhesion? Glycolipids or glycoprotein or both?

Answer 1

HEY WELCOME TO OS:)
where are the option??

Answer 2

Thanks Rina.r :)
I'm actually confused between the functions of glycolipids and glycoprotein on cell surface membrane. Do they have the same function? Because my textbook says both glycolipids and glycoproteins are for cell-cell adhesion. But my lecturer did not mention about glycolipids having a cell-cell adhesion function.

Answer 3

Glycolipids are located on cell membrane surfaces and have a carbohydrate sugar chain attached to them. They help the cell to recognize other cells of the body.

Structural proteins help to give the cell support and shape. Cell membrane receptor proteins help cells communicate with their external environment through the use of hormones, neurotransmitters and other signaling molecules. Transport proteins, such as globular proteins, transport molecules across cell membranes through facilitated diffusion. Glycoproteins have a carbohydrate chain attached to them. They are embedded in the cell membrane and help in cell to cell communications and molecule transport across the membrane.
