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 [...]
In this article we will discuss about the molecular structure of proteins with the help of diagrams. Quantitatively, proteins are the chief organic components of most living organisms, as also of viruses. About 50% of the dry weight of bacterial cells is protein. The flagella, pili and fimbriae are made up entirely of proteins, and the cell membrane, cytoplasm, ribosomes [...]
