Label The Specializations Of The Plasma Membrane

The lipid bilayer consists of phospholipids cholesterol and glycolipids which are differentially distributed in the two membrane leaflets. Typically microvilli are found in absorptive cells whenever there is a need for an increase in surface area.

The most common of these junctions are 1 tight junctions zonula occludens.

Label the specializations of the plasma membrane. On the other side of the plasma membrane are the cadherin family proteins. Jam junctional adhesion molecule. Select four differ ent colors and color the coding circles and the corresponding structures in the diagram.

Hollow cylinders formed by transmembrane proteins called connexons adjacent plasma membranes are very close together allows direct passage of chemical substances between adjacent cells you might also like.

The plasma membranes of neighboring cells in a tissue frequently exhibit specialized junctional regions that play a role in cell cell adhesion and in intercellular transport. The lipid tails of one layer face the lipid tails of the other layer meeting at the interface of the two layers. The oligosaccharide side chains of glycolipids are exclusively found on the outer plasma membrane surface together with the oligosaccharides of glycoproteins and form the glycocalyx cf.

I w 2. The plasma membrane consists of two adjacent layers of phospholipids. It is covered by a plasma membrane and encloses cytoplasm and microfilaments.

The phospholipid heads face outward one layer exposed to the interior of the cell and one layer exposed to the exterior figure 33. Then respond to the questions that follow referring to figure 31 and inserting your answers in the answer blanks. Intermediate filaments find to desmoplakin which binds to plakoglobin and then plakophilin.
