Question

Assertion A: Nickel is essential for the function of urease enzyme.
Reason R: Nickel helps in breaking down urea into NH\(_3\) and CO\(_2\).
In light of the above statements, choose the most appropriate answer from the options given below:

• A. Both A and R are correct and R is the correct explanation of A
• B. Both A and R are correct but R is NOT the correct explanation of A
• C. A is correct but R is not correct
• D. A is not correct but R is correct

Hint:

Nickel: essential for urease.
Urease: breaks urea to NH\(_3\) + CO\(_2\).
Nickel is a recent addition to plant nutrients.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Nickel is a micronutrient for plants.
It has a specific role in enzyme function.

Step 2: Key Formula or Approach:
No specific formula.
Need to understand the role of nickel in plants.

Step 3: Detailed Explanation:
Nickel is essential for the function of urease enzyme.
Urease breaks down urea into NH\(_3\) and CO\(_2\).
Thus, nickel is essential for this reaction.
Both A and R are correct, and R explains A.

Step 4: Final Answer:
Both A and R are correct and R is the correct explanation of A.
Hence, the correct option is (A).
