Question
I, SP 17 Ch 1, 8, 11 & 12 Time 80 mins 27. In glycoproteins, Points 75 a. Asparagine the sugars are attached through o dykosidiclinkage to the amino acids b. Serine c. Threonine d, a and b are correc e, band c are correct 28. New membrane synthesis occurs by la) the spontaneous aggregation of free phospholpids into a new bilayer in the squeous onment of the cell (b) incorporation of phospholipids into both faces of a preexistung membrane by enzymes attached each face ncorporation of phosphalipids as a single layer (d) incorporation af phospholipids in one face of a lipid bilayer and their specific to edistribution to the apposte mono layer by flippases 29. Which of the following statements regarding lipid membranes is TRUE? (a) Phospholipids will spontaneously form ipasomes in organic solvents. (b) In eucaryotes, all membrane-enclosed organelles are surrounded by single membrane (c) Membrane lipids move laterally within the ane of the membrane. pl d Loid bilayer is symme
Explanation / Answer
In glycoproteins sugars are arranged by o-glycosidic bonds to aa by serine and threonine.
New membrane synthesis occurs by incorporation of phospholipid as single layer.
In eukaryotes all membrane organelles are attached by single membrane.
Cholesterol does not contain a fatty acid tail.
