1.fluid mosaic model
A model that describes the structure of cell membranes. In this model, a flexible layer made of lipid molecules is interspersed with large protein molecules that act as channels through which other molecules enter and leave the cell.
One of three transport system.
In symport, two subtrates are moved simultaneously in the same direction.
One of three transport system. Transporters that carry only one substrate.
Compounds that shuttle ions across membranes.
5.Mutidrug resistance gene
Flippase facilitates flipflop diffusion, providing a transmembrane path that is much faster than the uncatalyzed movement.
Integral proteins :
hydrophobic interaction with membrane lipids.
Peripheral proteins :
electrostatic interactions and hydrogen bonding with the hydrophilic domains of integral proteins and with the polar head groups of membrane lipids
adhesives, and serve as receptors and signal transducers, conveying information across the plasma membrane in both directions.
undergo homophilic interactions wuth identical cadherins in adjacent cell
can undergo either homophilic interactions wuth their identical counterparts on another cell or heterophilic interactions with an integrin on a neighboring cell.S
have extracellular domains that, in the presence of Ca2+, bind specific polysaccharides on the surface of an adjacent cell.
