And this glycoprotein then is transferred onto the membrane of red blood cells. And it's the terminal sugar on that glycoprotein that determines the type of blood group or blood type that our individual actually has. So basically, let's take a look at the following diagram to see exactly what we mean. So, we have the phospholipid bilayer of the red blood cell. This is our cytoplasm portion, and this is the extracellular matrix. So this is the protein component of the glycoprotein.
