Almost all enzymes are:
1. Polysaccharides | 2. Proteins |
3. Nucleic acids | 4. Lipids |
I: | Almost all enzymes are proteins. |
II: | Some nucleic acids can behave like enzymes. |
III: | No enzyme in living organisms can function above 40 °C. |
IV: | Enzymes are the reason that chemicals react with each other. |
V: | Enzymes are not sensitive to pH in their environment. |
Consider the given two statements
Assertion (A): | In the absence of carbonic anhydrase, carbon dioxide will not react with water to produce carbonic acid. |
Reason (R): | Enzymes are the cause for the reactions to take place. |
1. | Both (A) and (R) are True and (R) correctly explains (A). |
2. | Both (A) and (R) are True but (R) does not correctly explain (A). |
3. | (A) is True, (R) is False. |
4. | (A) is False, (R) is False. |
I: | All enzymes are proteins. |
II: | All proteins are enzymes. |
Assertion (A): | Enzyme-catalyzed reactions proceed at rates vastly higher than that of uncatalyzed ones. |
Reason: | Enzymes require an optimum temperature and an optimum pH to work efficiently. |
1. | (A) is True but (R) is False. |
2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
3. | (A) is False but (R) is True. |
4. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
