Bound ribosomes generally make proteins that are destined for insertion into membranes, for packaging within certain organelles such as lysosomes, or for export from the cell. (For this statement, what does "Insertion into membranes" mean?)

Why is the advantage of using mammalian red blood cells for an experiment that is used to find out the surface area of the blood cells and also the surface area of phospholipid extracted from the same volume of blood?

http://www.youtube.com/watch?v=PUy_Em5dXmc this video might help you. RBCs don't possess membrane bound organelles like mitochondria , ER etc. The only membrane they contain is the plasma membrane. Therefore the phospholipid which you extract belongs only to the plasma membrane and this enables you to calculate the surface area of cells.
