Enzymes that catalyse the substrate level phosphorylation reactions in Glycolysis belong to

Options

A. Oxido reductases
B. Transferases
C. Hydrolases
D. Ligases

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the type of enzymes that catalyze substrate-level phosphorylation reactions in glycolysis.

2. **Identifying the Process**: Substrate-level phosphorylation is a process where a phosphate group is directly transferred to ADP to form ATP during glycolysis.

3. **Recognizing Key Enzymes**: One of the key enzymes involved in substrate-level phosphorylation in glycolysis is glyceraldehyde-3-phosphate dehydrogenase (GAPDH). This enzyme catalyzes the conversion of glyceraldehyde-3-phosphate to 1,3-bisphosphoglycerate, which involves the transfer of a phosphate group.

4. **Classifying the Enzymes**: The enzymes that facilitate the transfer of phosphate groups are classified under a specific category. These enzymes are known as transferases.

5. **Excluding Other Enzyme Classes**: Other classes of enzymes such as oxidoreductases, hydrolases, and ligases do not specifically catalyze the transfer of phosphate groups in the context of substrate-level phosphorylation.

6. **Conclusion**: Therefore, the enzymes that catalyze substrate-level phosphorylation reactions in glycolysis belong to the class of enzymes known as transferases.

**Final Answer**: The enzymes that catalyze the substrate-level phosphorylation reactions in glycolysis belong to the class of enzymes known as transferases.
