In this article we will discuss about Electron Transport System (ETS) in living organisms. Catabolism of energy-giving substrates (mostly glucose) up to the stage of pyruvic acid through EMP or EDP yields comparatively small amount of energy in the form of ATP by substrate-level phosphorylation. The anaerobic organisms have to be satisfied with this small amount of energy. But the [...]
The following points highlight the five main types of fermentation. The types are: 1. Alcoholic Fermentation 2. Lactic Acid Fermentation 3. Propionic Acid Fermentation 4. Butyric Acid — Butanol Fermentation 5. Mixed Acid Fermentation. Type # 1. Alcoholic Fermentation: Alcoholic fermentation generally means production of ethanol (CH3CH2OH). Commonly yeasts, particularly Saccharomyces cerevisiae, are used for production of various alcoholic beverages, [...]
In this article we will discuss about the regulation and control of metabolism in microorganisms. The biological organisms, specially microorganisms take up nutrients and metabolize them through numerous enzyme-catalysed reactions to build-up their body components as well as extract energy. All these anabolic and catabolic reactions run in a highly coordinated and harmonious manner to ensure optimal growth and multiplication [...]
