Question

Given below are the two statements.
Statements - I: According to international code of enzyme nomenclature, the first part in the name of an enzyme indicates the nature of substrate upon which the enzyme acts.
Statements-II: Second part in the name of an enzyme indicates the reaction catalysed by it.
In the light of above mentioned statements, choose the correct answer from the options given below.

• A. Both statement - I and statement - II are correct.
• B. Both statement - I and statement - II are incorrect.
• C. Statement - I is correct but statement - II is incorrect.
• D. Statement - I is incorrect but statement - II is correct.

Hint:

The IUB name has two parts, the substrate and then the reaction type ending in -ase.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept
The international (IUB) system gives each enzyme a name with two parts.

Step 2: Statement I
The first part names the substrate on which the enzyme acts, for example lactate in lactate dehydrogenase. So the statement is correct.

Step 3: Statement II
The second part names the type of reaction catalysed and ends in -ase, for example dehydrogenase for removal of hydrogen. So this statement is also correct.

Final Answer:
Both statements are correct. \[ \boxed{\text{(A) }\text{Both statement - I and statement - II are correct.}} \]
