Document Summary

!4! holds enzymes that function in metabolism lipid bilayer. 000000 phospholipids form a stable bilayer heads face. 3 tails face inward amphipatlc molecules w| both hydrophilic ( head ) 3 hydrophobic tails ) properties fluid mosaic lipid molecules form flexible bilayer protein molecules embedded in plasma membrane carbohydrates act as cell identification. Tags on surface of plasma membrane phospholipids rapid lateral movement. C bonds bent chains space tails apart make membrane. 37 c restrain movement of phospholipids cool temp maintain fluidity prevent tight packing of phospholipids. Specific functions peripheral proteins entirely on surface ionic. 3 protein groups integral proteins possess hydrophobic domains. Which are anchored to hydrophobic liplds transmembrane proteins span. Of for cell membrane cell cell or cell protein interactions glycohplds sugars attatched to a ex blood antigen that determine lipid blood type glycoprotein s sugars attatched to a protein ex protein receptors. !2! hydrophobic nonpolar molecules dissolve in lipid bilayer.
