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 [...]
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 [...]
The below mentioned article provides notes on multi-enzyme complex. Many enzymes in living cells catalyse chains of reaction in a sequential order either in a biosynthetic or a catabolic pathway. In the preceding paragraphs hypothetical examples of such pathways have been cited. The series of enzymes catalyzing such chains of reactions are said to form a multi-enzyme system. In its [...]
