In this article we will discuss about the patterns of carbon and energy metabolism in organisms. Carbon and energy metabolism are intimately associated in all living organisms. On the basis of the ability of organisms to obtain carbon and energy from usable sources, they can be divided into several categories. Considering the energy source first, organisms can be divided into [...]
In this article we will discuss about the molecular structure of nucleic acid with the help of diagrams. Nucleic acids constitute another important group of biological macromolecules present in all types of organisms where they function mainly as store-house of genetic information and as information- transfer molecules. Two types of nucleic acids: i. Ribonucleic acid (RNA) and ii. Deoxyribonucleic acid [...]
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 [...]
