Label The Specializations Of The Plasma Membrane

Associates with the claudins. Form aqueous channels for the paracellular transport of ionssmall molecules 2.

Correlative Ultrastructural Distribution Of Neurotensin Receptor

The lipid tails of one layer face the lipid tails of the other layer meeting at the interface of the two layers.

Label the specializations of the plasma membrane. Then respond to the questions that follow referring to figure 31 and inserting your answers in the answer blanks. Claudins backbone of the strands. 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 plasma membrane consists of two adjacent layers of phospholipids. The phospholipid heads face outward one layer exposed to the interior of the cell and one layer exposed to the exterior figure 33. Structure and functions figure 31 is a diagram of a portion of a plasma membrane.

Typically microvilli are found in absorptive cells whenever there is a need for an increase in surface area. Jam junctional adhesion molecule. I w 2.

It is covered by a plasma membrane and encloses cytoplasm and microfilaments. Intermediate filaments find to desmoplakin which binds to plakoglobin and then plakophilin. Select four differ ent colors and color the coding circles and the corresponding structures in the diagram.

The most common of these junctions are 1 tight junctions zonula occludens. Occludin maintains the barrier between the adjacent cells and between the basalapical compartment side to side and up to down 3.

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. Label the specializations of the plasma membrane shown in figure 32 and color the diagram as you wish. 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.

On the other side of the plasma membrane are the cadherin family proteins. The lipid bilayer consists of phospholipids cholesterol and glycolipids which are differentially distributed in the two membrane leaflets. Cell cell junctions and other specializations of the plasma membrane.

Then answer the questions provided that refer to this figure.
