Read the following statements and choose the correct option: 1. An enzyme has only secondary structure like protein 2. Enzymes, through their active site, catalyse reactions at a low rate 3. There are some nucleic acids that behave like enzymes. These are called ribozymes. 4. Inorganic catalysts work efficiently at high temperatures and high pressures, while enzymes get damaged at high temperatures. 5. A general rule

Step-by-step solution

An enzyme like any protein has the secondary and the tertiary structure. Enzymes, through their active site, catalyse reactions at a higher rate.,"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."
