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 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 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 [...]
