The below mentioned article provides a short note on the Reactions of Urea Cycle. Carbamoyl phosphate is formed by the condensation of one mol of phosphate (derived from ATP) being catalyzed by the enzyme carbamoyl phosphate synthetase which is present in liver mitochondria of all ureotelic organisms including humans. In addition to magnesium ion (Mg++), N-acetyl-glutamate (a dicarboxylic acid) is [...]
In this article we will discuss about the primary and secondary reactions of photosynthesis. Ruben and his co-workers in early 1943 used 18O and proved that oxygen evolved in photosynthesis came from water. Photosynthesis allowed to proceed in H2O18 and normal CO2, had molecular oxygen evolved with heavy isotopes. When photosynthesis was carried out in the presence of normal H2O [...]
In this article we will discuss about the Reactions of Antigen-Antibodies in Bacteria. When an antigen combines with its specific antibody in presence of an electrolyte (NaCl) in an optimum concentration at an optimal pH and temperature (37°C), the antigen and antibody complex forms an insoluble precipitate. Important tests for antigen-antibody reactions include precipitation, agglutination, complement fixation, neutralisation, and labelled [...]
