Enzymes that are required in nitrogen fixation should be determined. Concept introduction: Nitrogen fixation is the process by which the molecular nitrogen of the atmosphere is converted into ammonia or other nitrogenous compounds. Atmospheric nitrogen is unreactive and metabolically useless, so to make it useful, microorganisms convert it into useful nitrogenous compounds. Nitrogen fixation occurs between the termite and fungi .

Question

Chapter 24, Problem 1P

Interpretation Introduction

Interpretation:

Enzymes that are required in nitrogen fixation should be determined.

Concept introduction:

Nitrogen fixation is the process by which the molecular nitrogen of the atmosphere is converted into ammonia or other nitrogenous compounds. Atmospheric nitrogen is unreactive and metabolically useless, so to make it useful, microorganisms convert it into useful nitrogenous compounds. Nitrogen fixation occurs between the termite and fungi.

Expert Solution & Answer

Answer to Problem 1P

Option (a), Nitrogenase, and option (c), Reductase are the correct answer.

Explanation of Solution

Reason for correct option:

Option (a) is nitrogenase. Nitrogenase is the metalloenzyme that is involved in the conversion of molecular nitrogen into ammonia during the nitrogen fixation process. Hence, this option is correct.

Option (c) is reductase. In the nitrogen fixation process, the nitrate reductase enzyme is used to reduce nitrate into nitrite. This reaction is the nitrate assimilation process and the rate-limiting step in nitrogen fixation. Hence, this option is correct.

Conclusion

Reasons for incorrect options:

Option (b) is glutamine synthetase. Glutamine synthetase is a mitochondrial enzyme that catalyzes the formation of glutamine. During this process,the amide bond is formed between the ammonia and glutamate. This enzyme is mostly found in liver, kidney, and brain cells, and has no relation with nitrogen fixation. Hence, this option is incorrect.

Option (d) is glutamate dehydrogenase. This enzyme is involved in the interconversion of glutamate to alpha-ketoglutarate and ammonia. It is mostly found in liver, brain, pancreas, and kidney cells.

Students have asked these similar questions

The beta-lactamase hydrolyzes the lactam-ring in penicillin. Describe the mechanism of hydrolysis, insuring to include the involvement of S, D, & K in the reaction sequence. Please help

To map the active site of beta-lactamase, the enzyme was hydrolyzed with trypsin to yield a hexapeptide (P1) with the following amino acids. Glu, Lys, Leu, Phe, Met, and Ser. Treatment of P1 with phenyl isothiocyanate yielded a PTH derivative of phenylalanine and a peptide (P2). Treatment of P1 with cyanogenbromide gave an acidic tetrapeptide (P3) and a dipeptide (P4).Treatment of P2 with 1-fluoro-2,4-dinitrobenzene, followed by complete hydrolysis, yields N-2,4-dinitrophenyl-Glu. P1, P2, and P3 contain the active site serine. Why doesn't D in this hexapeptide not participate in the hydrolysis of the beta-lactam ring even though S, K, and D are involved in the catalyst?
