The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Organization**: The organization responsible for classifying enzymes is the International Union of Biochemistry and Molecular Biology (IUBMB). It is important to note the correct name of the organization. 2. **Number of Classes**: IUBMB has classified enzymes into a total of six distinct classes. This classification helps in understanding the function and mechanism of different enzymes. 3. **Listing the Classes**: The six classes of enzymes as per IUBMB are: - **Oxidoreductases**: Enzymes that catalyze oxidation-reduction reactions, where the oxidation state of molecules is changed. - **Transferases**: Enzymes that transfer functional groups from one molecule to another. - **Hydrolases**: Enzymes that catalyze the hydrolysis of various bonds, breaking down molecules by adding water. - **Lyases**: Enzymes that catalyze the addition or removal of groups to form double bonds or break them without hydrolysis. - **Isomerases**: Enzymes that catalyze the rearrangement of atoms within a molecule, converting it into its isomer. - **Ligases**: Enzymes that join two molecules together, often using energy derived from the breakdown of ATP. 4. **Conclusion**: Based on the classification provided by IUBMB, the correct answer to the question is that enzymes are divided into six classes. **Final Answer**: The IUBMB has divided enzymes into six classes. ---
