C. | Glut-4 | III. | Lipid |
D. | Vitamins | IV. | Coenzyme |
Consider the following statements:
A: | A coenzyme or metal ion that is tightly bound to enzyme protein is called prosthetic group |
B: | A complete catalytic enzyme with its bound prosthetic group is called apoenzyme |
Select the correct option
1. (A) is false but (B) is true
2. Both (A) and (B) are true
3. (A) is true but (B) is false
4. Both (A) and (B) are false
Prosthetic groups differ from co-enzymes, in which:
1. | they require metal ions for their activity. |
2. | they (prosthetic groups) are tightly bound to apoenzymes. |
3. | their association with apoenzymes is transient. |
4. | they can serve as co-factors in a number of enzyme-catalyzed reactions. |
An organic substance bound to an enzyme and essential for its activity is called:
1. coenzyme
2. holoenzyme
3. apoenzyme
4. isoemzyme
The essential chemical components of many coenzymes are:
1. Nucleic acid
2. Carbohydrates
3. Vitamins
4. Proteins
For its activity, carboxypeptidase requires:
1. Iron
2. Niacin
3. Copper
4. Zinc
