adhere tightly to cytoplasmic or extracellular surfaces; non-covalently bonded
peripheral proteins
interact through ionic interactions with 'phospholipid head'
'salt bridges' with adherent proteins
intercellular signaling
direct binding of peripheral proteins to the extracellular or cytoplasmic surface of integral proteins
submembranous cytoskeleton
intimately associated with lipid bilayer. functions as receptors, channels, pores, carriers, and pumps
integral proteins
loose carbohydrate coat found in the entire outside surface of the cell. gives an overall negative charge that repels other negative objects. attaches one-cell to another. receptor substances for binding hormones
glycocalyx
where the transcription of ribosomal RN and assembly of ribosomal subunits occur
nucleoli
fibrillar skeleton in the interior surface of the inner nuclear membrane; provide structural support
