The below mentioned article provides study notes on Isoenzymes. Isoenzymes or isozymes are proteins which have different molecular and physicochemical properties, but have identical catalytic activity. They generally occur in branched metabolic pathways in which several end-products are synthesized from a common precursor molecule. A hypothetical branched pathway in which three different end-products, X, Y and Z, are synthesized from [...]
In this article we will discuss about the structure of various energy-rich compounds with the help of diagrams. The chief energy-rich compound of all biological cells is adenosine triphosphate. ATP consists of adenine, ribose and three phosphoric acid molecules. ATP is energy-rich because its terminal phosphate group can be hydrolysed to release energy. Many biochemical reactions are endergonic in nature [...]
The below mentioned article provides study notes on bioluminescence which is an interesting aspect of energy metabolism. Bioluminescence or emission of light by biological organisms is an interesting aspect of energy metabolism. Many different kinds of organisms, both prokaryotic and eukaryotic, show this property. Among the bacteria, bioluminescent species occur in the genera, Photo-bacterium, Vibrio and Beneckea. Many marine dinoflagellates [...]
