The correct Answer is:
To solve the question regarding the enzyme coded by E.C. 2.7.1.2 in modern classification, we will follow these steps: ### Step-by-Step Solution: 1. **Understand the EC Number**: The EC number 2.7.1.2 indicates a specific enzyme classification. The first digit (2) signifies that it is a transferase, which is an enzyme that transfers a functional group from one molecule to another. 2. **Break Down the EC Number**: - The second digit (7) indicates that it transfers a phosphate group. - The third digit (1) specifies that it acts on alcohols. - The fourth digit (2) identifies the specific enzyme within this category. 3. **Identify the Enzyme**: - We need to find which enzyme corresponds to the EC number 2.7.1.2. - The options given are: - Hexokinase (E.C. 2.7.1.1) - Aldolase (E.C. 4.1.2.13) - Inolase (E.C. 4.2.1.11) - Glucose 6-phosphate transferase (E.C. 2.7.1.2) 4. **Match the Options**: - Hexokinase is coded by 2.7.1.1, which does not match. - Aldolase is coded by 4.1.2.13, which does not match. - Inolase is coded by 4.2.1.11, which does not match. - Glucose 6-phosphate transferase is coded by 2.7.1.2, which matches perfectly. 5. **Conclusion**: The enzyme that corresponds to E.C. 2.7.1.2 is glucose 6-phosphate transferase, also known as glucokinase. ### Final Answer: The enzyme coded by E.C. 2.7.1.2 is **Glucose 6-phosphate transferase**. ---
