A
Proteins in cell membranes can travel with in the lipid bilayer

B
Proteins can also undergo flip-flap movements in the lipid bilayer

C
Proteins can remain confined within certain domains of the membrane

D
Many proteins remain completely embedded within the lipid bilayer

There are many different proteins embedded in the membrane. Except for flip flop movements rest occurs. Choice (a) is amply demonstrated when the travelling proteins aggregate at sites of endocytosis. Choice (c) type of proteins can be enzymes which are confined to cetrain domains (for e.g., present only on cell surface) choice (d) types are non-trasmembrane proteins.

In this chapter, we described co-immunoprecipitation as a method for identifying binding partners to a protein of interest. A simpler variation of this method can also be used to isolate proteins of low abundance in a complex mixture. Arrange the steps in sequential order to use this technique for this purpose First step An antibody against the protein of interest is added to the mixture. Protein A beads are added to the mixture. The antibody binds to the protein of interest. The antibody-protein complexes become insoluble. The protein mixture is centrifuged, the supernatant is removed, and the pellet is washed Last step
