Formation of biological membranes.
For this there should be a lipid synthesis in the agranular reticulum and protein biosynthesis in the rough surfaced endoplasmic reticulum. These two major components are arrayed giving rise to the membrane. With respect to the formation of plasma membrane, Golgi complex also comes into play as it have to produce the overcoat.In other words, it has to add carbohydrate moiety to the protein already formed in the RER.

A membrane basically is made of lipids,proteins,preferably glycoproteins. Formation of membranes r cateogerised in many aspects. For example, On Formation type basis----Apposition & Superposition
Appos____:- Membranes r formed by mutual partial overlapping. dis causes thickness growth of d membrane ,without correct defined strata..
Superpo________:- Membranes r formed by correct overlapping.( not as sudden blind END as in Appos____).
In Superpo____, thickness z grown, but d thickness growth has definite direction ( either frm OUTER to INNER or VICEVERSA )......
Membrane Biogenesis,z d formation of d membrane,at cond. of availability of nutrients( CHO, Fats,Proteins etc.,) & minerals like Mg,Cu,K,Na etc.,( in trace amounts n in ionic form..). But dis z controlled by Release of 'mRNA' , inside membrane-- 'tRNA' controls......ie., with gene held control also.
Also it is influenced with circumstances ( during tissue repair / need-- immune responsed formation etc.,).
Thtz it.................Anyway search in google/ yahoo search..
