Read the following statements and choose the correct option: 1. Without enzyme, 200 molecules of H2CO3 being formed in an hour. 2. By using the enzyme Carbonic anhydrase, the reaction speeds dramatically with about 600,000 molecules being formed every second. 3. Enzymes which catalyse oxidoreduction between two substrates fall under oxidoreductase category. 4. Catalytic activity is lost when the cofactor is removed f

Step-by-step solution

In the absence of any enzyme this reaction is very slow, with about 200 molecules of H2CO3 being formed in an hour. However, by using the enzyme present within the cytoplasm called carbonic anhydrase, the reaction speeds dramatically with about 600,000 molecules being formed every second.,Fats and oils are differentiated based on melting point. Oils have lower melting point and hence remain as oil in winters. Phospholipids are found in cell membranes.
