Ans Membranes and their constituent proteins are assembled in the ER This organelle contains the enzymes involved in lipid synthesis and as lipids are manufactured in the ER they are inserted into the organelles own membranes This happens in part because the lipids are too hydrophobic to dissolve into the cytoplasm Similarly transmembrane proteins have enough hydrophobic surfaces that they are also inserted into the ER membrane while they are still being synthesized Here future membrane proteins make their way to the ER membrane with the help of a signal sequence in the newly translated protein The signal sequence stops translation and directs the ribosomes which are carrying the unfinished proteins to dock with ER proteins before finishing their work Translation then recommences after the signal sequence docks See Answer
