Some membrane lipids and integral proteins remains bound to oligosaccharides which project into the extracellular fluid.Q. Superficially attached proteins are called extrinsic or peripheral proteins and can be easily removed. There are large globular integral proteins which project beyond the lipid layer on both the sides. Some proteins are embedded in the lipid layer are called integral or intrinsic proteins and they cannot be separated from the membrane. According to this model, there is a central lipid bilayer of phospholipids with their polar head group towards the outside and the non-polar tails pointing inwards. Information about Fluid mosaic model was proposed by Singer and Nicolson. The Question and answers have been prepared Can you explain this answer? for NEET 2023 is part of NEET preparation.
