The density of the plasma membrane of a cell was found to be 1.06 g/mL. If the density of the lipid component is 0.90 g/mL and the density of the protein component is 1.36 g/mL, what is the percent composition (to the nearest ones) of the lipid component of the membrane, assuming the plasma membrane consists only of the lipid and protein components?

How does G⍺ stay associated with the plasma membrane after release from GPCR? Lipid rafts. G⍺ is phosphorylated. G⍺ is farnesylated. G⍺ is palmitoylated. G⍺ is covalent bound to positive charge of phospholipids. G⍺ contains a transmembrane domain that is enriched for hydrophobic residues. Why is it important that G⍺ stay associated with the plasma membrane after release from GPCR? It isn’t, in fact this is one way to prevent “runaway signaling” (i.e. how G⍺ acts as a molecular timer)...
