Name two components of the plasma membrane that can act as receptor sites for cell signalling / recognition:[2] Glycoproteins / glycolipids. Proteins held by the membrane. Suggest why glycolipids are only found on the outside surface of the plasma membrane [2] Associated with cell recognition . Interact with transmitter substances outside of ...

the question – where are the proteins located in the cell membrane. Davson. and Danielli proposed . a sandwich model: the cell membrane is a phospho-lipid bilayer between two layers of proteins. ( #4.Add Singer & Nicolson…) 3. Cell biologists recognized two problems with this model. a) The generalization that all cell membranes are identical.

At least 50 different proteins associated with a cell membrane. Proteins and lipids drift laterally. Do not flip-flop. Saturated lipids cause the membrane to be more rigid; unsaturated fatty acids increase the fluidity. Cholesterol stabilizes the membrane at higher temperatures and prevents it from getting too rigid at cooler temperatures. Synthesis

The plasma membrane is a fluid, or mobile, mosaic of lipids and proteins. Ions and molecules cross the plasma membrane by a number of processes. Large particles are engulfed by the membrane, forming a vesicle or vacuole that can pass into (endocytosis) or …
