The number which represent class to which transphorphorylase belongs to

Options

A. 2
B. 1
C. 7
D. 6

Answer

To determine the class to which transphosphorylase belongs, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Term "Transphosphorylase":**
- Transphosphorylase is an enzyme that catalyzes the transfer of a phosphate group from one molecule to another. This process is known as transphosphorylation.

2. **Identify the Enzyme Classification System:**
- Enzymes are classified into different classes based on the type of reaction they catalyze. The Enzyme Commission (EC) number system is commonly used for this classification.

3. **Determine the Class of Transphosphorylase:**
- Transphosphorylases are involved in the transfer of phosphate groups. According to the EC classification, enzymes that transfer functional groups are classified under class 2.

4. **Conclusion:**
- Therefore, the number that represents the class to which transphosphorylase belongs is **2**.

### Final Answer:
Transphosphorylase belongs to class **2**.
