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 [...]
The following points highlight the top three pathways of glucose dissimilation in organisms. The pathways are: 1. Embden-Meyerhof Pathway or Glycolysis 2. Pentose Phosphate Cycle (PPC) 3. Entner-Doudoroff Pathway (EDP). Glucose Dissimilation: Pathway # 1. Embden-Meyerhof Pathway or Glycolysis: This catabolic pathway leads to splitting of glucose to two molecules of pyruvic acid i.e. a six- carbon compound is broken [...]
The below mentioned article provides notes on hydrocarbon metabolism in organisms. Hydrocarbons are organic compounds containing carbon and hydrogen. The simplest hydrocarbon is methane (CH4). A host of bacteria can also use other hydrocarbons like alkanes, alkenes, cyclic and aromatic compounds. Alkanes are linear saturated hydrocarbons having the general formula CH3-(CH2)n-CH3, while alkenes are unsaturated linear molecules. Some examples of [...]
