In this article we will discuss about competitive and non-competitive reversible enzyme inhibition. Competitive Inhibition: The main feature of competitive inhibition is that it can be reversed by increasing the substrate concentration in a reaction mixture which contains both the substrate and the inhibitor. The degree of inhibition depends on the relative concentrations of the substrate and the inhibitor. If [...]
In this article we will discuss about oxidation-reduction reactions in living organisms. In biological systems energy is generally released from oxidation-reduction reactions of organic compounds catalysed by enzymes. It is, therefore, necessary to understand clearly the nature of oxidation-reduction reactions occurring in living systems. The most common organic compound used as substrate for energy production is glucose. When one mole [...]
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 [...]
