(a) What basic organizational principle underlies both ECM and cell walls?
(b) What are the chemical constituents in each case?
(c) What functional roles do the ECM and cell wall have in common?
(d) What functional roles are unique to the ECM? To the cell wall?

Question:-
Give a brief description of what the term ‘native protein’ state refers to. Your answer should make a specific reference to how the structural organisation of this state is accomplished
Question:-
Given the very complex lipid composition of cell membranes, what variations exist within the different membranes of organelles in an animal cell? What are the functional consequences of these differences?
Although proteins rarely if ever flipflop across a membrane, the distribution of membrane lipids between the membrane leaflets is not absolute except for glycolipids. Why are glycosylated lipids less likely to flip-flop?
