Cell membrane has proteins, lipids and carbohydrates. With respect to their mutual proportions, which statement is correct ?

Keeping in view the fluid mosaic model for the stucture of cell membrane, which one of the following statements is correct with respect to the movement of lipids and proteins from one lipid mono layer to the other (described as flip flop movement)

A student made a pictorial representation of a eukaryotic cell membrane and labelled the components as follows. The student has made errors while labelling the components membrane. Which of the following hold true regarding the error ? (i) Protein A should be labelled as trans-membrane protein only and not as integral protein. (ii) The polarity of the protein A should be reversed because the cytosolic phase always shows reducing environment. (iii) Position of cholesterol molecule should be close to polar region as it contains a polar group. (iv) Protein B should be labelled as integral membrane protein and not as peripheral glycoprotein.

(i) Mitochondria and chloroplasts possess small and circular non-histones DNA. (ii) Mesosomes are extension of plasma membrane .

In the first biological applicativon of bucky ball , chemists at the University of Califorminaat San F Francisoc and Santa Barbra made a discovery in 1993 that could help I designing drugs to rtreat AIDS . The human immunodeficienrcy virus (HIV) that causes AIES reproduces by syntheising a long protein chain , which is cut into smaller segments by an enzymecalled HiV-proteases . ONe way to stop AIDS , then might be to inacivate the enzyme. when the chemists reacted a water-soluble derivative of bucky ball with HIV-protease , they found that itbinds to the portion of th enzyme that would ordinarily clareve the repreouctive protein , preventing the HIV virus from reproducing . Consequently the virus could no bnolgre infect the human cells they had frown in the laboratory . The buycky ball compound itself is not a suitable drug for use against AIDS because of potential side effects and delivery difficaultes , but it does provide a model for the development of such drugs Consider following statements about bucky ball : A , It is also called fullerene B: It is also called Buckminster fullerene C: Bucky tubes (made of fullerenes ) are several times stronger than steel wires D: Bucky ball is a plastic polymer Select correct statement (s) :
