If an enzyme has been given the EC code 5.2.1.7, it is likely to be involved in

Options

A. Digestion
B. Redox reaction
C. Isomerization
D. Molecular breakdown

Answer

To determine the likely involvement of the enzyme with the EC code 5.2.1.7, we can follow these steps:

### Step 1: Understand the EC Code Structure
The Enzyme Commission (EC) code is a four-digit number that classifies enzymes based on the reactions they catalyze. Each digit has a specific meaning:
- The **first digit** indicates the main class of the enzyme.
- The **second digit** indicates the subclass.
- The **third digit** indicates the sub-subclass.
- The **fourth digit** indicates the specific enzyme within that sub-subclass.

### Step 2: Identify the First Digit
In the EC code 5.2.1.7, the first digit is **5**. According to the classification:
- **EC 5** corresponds to **isomerases**. Isomerases are enzymes that catalyze the rearrangement of molecular structures.

### Step 3: Determine the Type of Reaction
Since the first digit indicates that the enzyme is an isomerase, we can conclude that this enzyme is involved in isomerization reactions.

### Step 4: Verify the Other Digits
The remaining digits (2.1.7) provide further classification within the isomerase category, but for the purpose of this question, we only need to focus on the first digit to determine the main function of the enzyme.

### Conclusion
Therefore, the enzyme with the EC code 5.2.1.7 is likely to be involved in **isomerization** reactions.
