Assertion: Manganese is an activation of enzyme nitrite reductase
Reason : Manganese deficient cells prefer ammonia over nitrate

A

Both Assertion and Reason are true and Reason is the correct explanation of assertion

B

Both assertion and Reason are true, but reason is not the correct explanation of assertion

C

Assertion is true, but reason is false

D

Assertion is false, but reason is true

Text Solution

Verified by Experts

The correct Answer is:
A
Manganese plays an important role in nitrate reduction. Manganese acts as an activator for the enzymes nitrate reductase and hydroxlamine reductase. The preference of ammonia over nitrate as a nitrogen source by the manganese-ddeficient cells supports the above mentioned analysis of the role of manganese.
