Q. No.Most of the plants can assimilate……a….. and ……b… and…c. is quite toxic to plants and hence cannot accumulate in them.
Find the correct one.
1. a. Ammonia
2. c. Ammonium ions
3. c. Nitrate
4. b. Nitrite
Find the correct one.
1. a. Ammonia
2. c. Ammonium ions
3. c. Nitrate
4. b. Nitrite
Ammonium is used to synthesise amino acids in plants which of the following is not a way?
(1) Reductive Amination
(2) Transamination
(3) Oxidative amination
(4) All of these
Reductive amination 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 ke to 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
Asparagine is
(1) Amide formed by addition of another amino group to glutamate
(2) Two amino groups over carboxy group of aspartate
(3) One amino group over hydroxy part of aspartic acid
(4) All of these
