In this article we will discuss about the mechanism of enzyme reaction. In an enzyme-catalysed biochemical reaction, the enzyme molecule binds specifically and reversibly to the substrate molecule resulting in formation and breaking of chemical bonds to produce the product. Thus, there is formation of an unstable enzyme-substrate complex which immediately breaks into the product. This can be simply represented [...]
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 [...]
