The nitrogen fixing bacteria are
(1) Always free living
(2) Generally free living aerobes but during nitrogen fixing event it becomes anaerobic
(3) Always anaerobic
(4) Generally anaerobic but under nitrogen fixing event, it becomes aerobic
The energy required, for the process of nitrogen metabolism comes from
(1) Respiration of the host cells
(2) Oxidation of the host cells
(3) Respiration of the bacterial cells
(4) Oxidation of the bacterial cells
Which of the following process is not used by plants to synthesize amino acids from ammonia?
1. Reductive amination
2. Transamination
3. Oxidative amination
4. All of the above
Reductive animation is:
1. Conversion of ammonia to alpha ketoglutarate and forms glutamate
2. Ammonia reacts with alpha ketoglutarate and forms glutamate
3. Ammonia reacts with glutamate and forms alpha-ketoglutaric acid
4. Conversion of ammonia to glutamate
Which of the following is an ezyme of reductive animation?
(1) Glutamate oxidase
(2) Glutamate dehydrogenase
(3) Glutamate carboxylase
(4) Aspartate oxidase
During reductive animation
(1) NADH gets converted to NAD+
(2) NADPH gets converted to NADP
(3) NADP gets converted to NADPH
(4) NAD+ gets converted to NADH
Transamination:
(1) Involves the transfer of amino group from one amino acid to the keto group of keto acid.
(2) Involves the transfer of amino group from one amino acid to the amino group of another amino acid.
(3) Involves the transfer of keto group from one amino acid to the keto group of keto acid.
(4) Involves the transfer of keto group of keto acid to the keto group of keto acid.
Transamination involves an enzyme?
(1) Transaminase
(2) Dehydrogenase
(3) Transaminase reductase
(4) Reductive dehydrogenase
The main amino acid over which Transamination occurs.
(1) Glutamate
(2) Alanine
(3) Glycine
(4) Lysine
The most important amides of plants are
(1) Asparagine
(2) Glutamine
(3) a structural part of proteins
(4) All of these
