Hydolytic enzymes comprises of which of the following
| 1. | lipases | 2. | proteases |
| 3. | carbohydrases | 4. | All of these |
| 1. | Lysosomes | 2. | Centrosome |
| 3. | Peroxisomes | 4. | Glyoxysomes |
The isolated lysosomal vesicles have been found to be very rich in:
| 1. | phosphate and chloride ions |
| 2. | cytoprotective pigment molecules |
| 3. | lymphokines like interleukins and interferons |
| 4. | acid hydrolases |
| 1. | Peroxisomes – contain oxidative enzymes for detoxification and fatty acid breakdown |
| 2. | Lysosomes – contain acidic hydrolases for degradation of biomolecules |
| 3. | Golgi apparatus – modifies, sorts, and packages proteins for secretion |
| 4. | Endoplasmic reticulum – involved in protein synthesis and lipid metabolism |
Hydrolytic enzymes are active at
| 1. | acidic pH | 2. | basic pH |
| 3. | Neutral pH | 4. | Both A and B |
Membrane bound vesicular structure formed by the process of packaging in the Golgi apparatus
| 1. | Contains materials not useful for cell and is bounded by half unit membrane |
| 2. | Contains all types of hydrolytic enzymes optimally active at the acidic pH |
| 3. | Are concerned with photorespiration in plants and animals |
| 4. | Possess enzymes for Krebs cycle |
Which one of the following cellular parts is correctly described?
| 1. | Thylakoids-flattened membranous sacs forming the grana of chloroplasts |
| 2. | Centrioles - sites for active RNA synthesis |
| 3. | Ribosomes-those on chloroplasts are larger (80S) while those in the cytoplasm are smaller (70S) |
| 4. | Lysosomes-optimally active at a pH of about 8.5 |
