Almost all enzymes are:
1. Polysaccharides | 2. Proteins |
3. Nucleic acids | 4. Lipids |
In the absence of carbonic anhydrase in the human body, the reaction between carbon dioxide and water leading to the formation of carbonic acid:
1. Will not occur | 2. Will slow down considerably |
3. Will get faster | 4. Will remain unaltered |
Which of these can have catalytic activity?
1. RNA | 2. DNA |
3. Prostaglandins | 4. Sterols |
Enzymes speed up the chemical reactions by:
1. Getting used up in the reaction
2. Formation of different products
3. Converting endothermic reactions to exothermic
4. Lowering activation energy
