Q.1
ion Q36) According to the fluid mosaic model of plasma membrane:
0%
a) Non polar tails of phospholipids are towards cytoplasm.
0%
b) Quasi fluid nature of lipids enables lateral movement of proteins within the overall bilayer.
0%
c) Peripheral proteins are partially or totally buried in the membrane.
0%
d) Both A and B.
Explanation
Singer and Nicolson (1972) proposed fluid mosaic model of plasma membrane. According to this model plasma membrane contains a lipid bilayer, which are interrupted by protein molecules. Some proteins attached at the polar surface of lipid (called, extrinsic proteins) while other partialy penetrate the lipid bilayer (called, intrinsic proteins). Intrinsic proteins are tightly binded whereas the extrinsic proteins are loosely binded to the lipid bilayer. The nature of the lipid which helps in the lateral movement of protein molecules through the membrane bilayer is called quasi fluid nature of lipid The protein can move through the membrane by the help of this characteristic of lipid Answer:(b)

Q.27
ion Q62) Find out the incorrect statement:
0%
a) Porin proteins are seen on the cell wall of Gram negative bacteria.
0%
b) Murein content of Gram positive bacteria is 70 - 80%.
0%
c) Gram positive bacteria are less susceptible to antibiotics.
0%
d) Flagella basal body has 4 rings in Gram negative bacteria.
Explanation
A Gram positive organism lacks an outer (LPS) membrane but has a thick layer of peptidoglycan and no LPS outer membrane. This facilitates access of cell-wall active antibiotics (eg. penicillin/betalactam or vancomycin-type antibiotics) to their site of action (the peptidoglycan). Statement ‘c’ is incorrect statement Porin are present in the outer membrane of gram-negative bacteria and some gram-positive mycobacteria (mycolic acid-containing actinomycetes), the outer membrane of mitochondria, and the outer chloroplast membrane. Statement ‘a’ is correct statement Chemically, 60 to 90% of the Gram-positive cell wall is peptidoglycan or murein is a polymer consisting of sugars and amino acids that forms a mesh-like layer outside the plasma membrane of most bacteria. Statement ‘b’ is correct statement In Gram-negative bacteria there are two pairs of rings i.e. four rings are L-(lipopolysaccharide) ring, P-(peptidoglycan) ring, S-(super membrane) ring, and M-(membrane) ring. Outer membrane in Gram negative bacteria is made up of Lipopolysacchride (LPS). It is this layer which contributes to the pathogenicity in Gram negative bacteria which is absent in Gram positive bacteria.Gram-positive bacteria have a single pair of rings. The S-ring is attached to inside thick layer of peptidoglycan and M-ring is attached to cell membrane Answer:(c)

b) Lysosomes - Optimally active at a pH of about 8.5.
0%
c) Thylakoid - Flattened membranous sacs forming the grana of chloroplasts.
0%
d) Ribosomes - Those on chloroplasts are larger (80S) while those in the cytoplasm are smaller (70S).
Explanation
Thylakoid - Flattened membranous sacs forming the grana of chloroplasts. Option c is correctly matched. Centrioles are involved in the formation of the spindle apparatus, which functions during cell division. RNA Synthesis takes place within the nucleus of eukaryotic cells. Option a is not correct match. Lysosomes enzymes are active in acidic conditions, requiring the organelle to maintain an optimal luminal pH between 4 and 5. Option b is not correct match. Ribosomes in chloroplast are 70 s type while those of cytoplasm in eukaryotic cells are 80 S type. The enzymes of lysosome (called suicidal bag) function at acidic pH (i.e., 5). Option d is not correct match. Answer:(c)
