Assertion: The enzyme nitrogenase is a Mo-Fe protein and catalyses the conversion of atmospheric nitrogen to ammonia.
Reason: The enzyme nitrogenase is highly sensitive to the molecular oxygen.

A

If both assertion and reason are true and reason is the correct explanation of assertion

B

if both assertion and reason are true but reason is not the correct explanation of assertion

C

if assertion is true but reason is false

D

if both assertion and reason are false

Text Solution

Verified by Experts

The correct Answer is:
B
The enzyme nitrogenase is a Mo-Fe protein and catalyses the vonversion of atmospheric nitrogen to ammonia, which is the firsta stable product of nitrogen fixation. The enzyme nitrogenase is highly sensitive the the molecular oxyge , it requires anaerobic conditions. the nodules have adamptationsn that ensure that the enzyme is protected from oxygen.

Assertion : The protein part of the enzyme is called apoenzyme and non-protein part of the enzyme is called co-factor. Reason : Zinc is a co-factor for the proteoilytic enzyme carboxypeptidase.

Assertion : Nitrogenase enzyme gets inactivated in presence of oxygen yet N_(2) fixation occurs in aerobic cells of legume nodules. Reason : Leghaemoglobin allows presence of oxygen just sufficient for cellular respiration only.

Assertion : Lysosomes are capable of digesting carbohydrates, proteins, lipids and nucleic acids. Reason : Lysosomes are rich in hydrolytic enzymes like lipases, proteases and carbohydrates.

Assertion : The inhibition of activity of succinic dehydrogenase by malonate which closely resembles the substrate succinate in structure is the example of competitive inbhibition. Reason : Competitive inhibition is the inhibition of enzyme activity when inhibitor closely resembles the substrate, in its molecular structre.
