The correct Answer is:
To solve the question regarding which class of enzymes catalyzes the joining of C-O, C-S, P-O bonds between two compounds, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Question**: The question asks about enzymes that catalyze the joining of specific bonds (C-O, C-S, P-O) between two compounds. This indicates that we are looking for enzymes that facilitate the formation of covalent bonds. 2. **Examine the Options**: - **Option 1: Hydrolysis**: Hydrolytic enzymes break down compounds by adding water, which results in the cleavage of bonds. This means they do not join compounds but rather separate them. Therefore, this option is incorrect. - **Option 2: Isomerases**: Isomerases are enzymes that convert one isomer into another. They do not catalyze the joining of two different compounds but rather rearrange the structure of a single compound. Thus, this option is also incorrect. - **Option 3: Transferases**: Transferases catalyze the transfer of functional groups from one molecule to another. While they do involve the movement of parts of molecules, they do not specifically catalyze the joining of two compounds into a larger molecule. Hence, this option is incorrect as well. - **Option 4: Ligases (or Synthetases)**: Ligases are enzymes that catalyze the joining of two compounds by forming covalent bonds, such as C-O, C-S, and P-O bonds. They are responsible for linking molecules together, making this option the correct choice. 3. **Conclusion**: Based on the analysis of the options, the correct answer is **Option 4: Ligases (or Synthetases)**, as they are the enzymes that catalyze the joining of compounds by forming covalent bonds. ### Final Answer: The enzymes which catalyze the joining of C-O, C-S, P-O, etc., between two compounds are kept under **Ligases (or Synthetases)**. ---
