2. Only II
3. Both I and II
4. Neither I nor II
I: A is the flagellum which is made of protein flagellin and is made of a filament, a hook, and basal body.
II: B is lysosome which is a double membrane-bound organelle.
III: C is the centrosome and it has two centrioles oriented perpendicular to each other.
IV: D is peroxisome and has catalase present in it.

| 3. Only II and III | 4. Only III and IV |
I: A is a major component of animal plasma membranes and it regulates the fluidity of the overall membrane.
II: B are integral proteins and C is an extrinsic protein.
III: D is the hydrophobic head of the phospholipid and E is its hydrophilic tail.
IV: F is a carbohydrate found only on the outer surface of the membrane.

| 3. Only II, III, and IV | 4. I, II, III and IV |
Study the given diagram and select the correct statements regarding the parts labels I, II and III.
A: I are ribosomes and found only in eukaryotic cells.
B: II is Rough Endoplasmic Reticulum frequently observed in cells actively involved in protein synthesis and secretion.
C: III is Smooth Endoplasmic Reticulum which is a major site for synthesis of lipids.
| 1. Only A and B | 2. Only A and C |
| 3. Only B and C | 4. A, B and C |
I: A is the cis face and B is the trans face.
II: The two faces are entirely different but inter-connected.
1. Only I is correct
