1 Most of the enzymes get damaged above${{40}^{\circ }}\text{C}$
2 The rate of chemical reaction decreases by half for every${{10}^{\circ }}\text{C}$ change in either direction
3 The enzyme carbonic anhydrase accelerates the rate of hydration of$\text{C}{{\text{O}}_{2}}$ by about 10 million times
4 All of these

Which of the following is wrongly matched?
1 Ribożyme - Proteinaceous in nature.
2 Apoenzyme - The protein part of enzyme.
3 Co-enzyme - Loosely attached organic cofactor of haloenzyme
4 Co-factors - Non-protein part of haloenzyme.
Explanation:
(a) Ribozymes (ribonucleic acid enzymes) are also called catalytic RNA. They are RNA molecules capable of catalysing specific biochemical reactions, similar
to the act of protein enzymes. Ribozyme, discovered in 1982, demonstrated that RNA can be both genetic material (like DNA) and a biological catalyst (like protein enzymes). Examples of ribozymes include the hammerhead ribozyme, the VS ribozyme, Leadzyme and the hairpin ribozyme.
