BIOCHEMICAL TESTS Nitrate reduction test The presence of enzyme nitrate reductase which can convert nitrate into nitrite can be identified by using this test. Steps: . Bacteria is grown in media containing 1% w/v potassium nitrate for 5-7 days at […]
CLASSIFICATION AND CHARACTERISTICS OF BACTERIA Classification of bacteria on basis of their basic cell shapes Cocci: Unicellular, spherical or elliptical shape. Monococcus: A single discrete round shape. Eg: Micrococcus flavus Diplococcus: Two spherical shaped bacteria attached with each other. Eg: […]
Gluconeogenesis is the process for the synthesis of new glucose from the non-carbohydrate precursors. The precursors are as follows: Lactate:- It is generated from pyruvate in glycolysis. It is then transferred to the liver by CORI’s cycle; and then is […]
Proteins are the macromolecules and are composed of one or more polypeptide chains. Each of these polypeptide chains contains a specific sequence of amino acids. These polypeptide chains are linked by peptide bonds. Proteins are classified in several ways. Mainly […]
For the catabolism of amino acid, following stages are involved. Removal of alpha-amino group in the form of ammonia by following reactions. Transamination:- Catalyzed by aminotransferase or transaminase. Deamination:- It may be oxidative or non oxidative Oxidative deamination:- Catalyzed by […]
Kreb’s Henseleit Urea Cycle:– The urea is the final metabolic product of protein. It is a non-toxic form of a toxic NH4 generated in tissues. Urea is exclusively produced in liver and then transported through the blood to the kidneys […]
