The following points highlight the three main heterotrophic reactions operating in different living systems. The reactions are: 1. Reactions in which NADPH2 is Required 2. Reactions Requiring ATP 3. Reactions Requiring no Apparent Energy Source. 1. Reactions in which NADPH2 is Required: Two examples of this type are malic enzyme catalysed CO2 incorporation in pyruvic acid, and synthesis of isocitric [...]
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 [...]
In this article we will discuss about the molecular structure of carbohydrates with the help of diagrams. Carbohydrates are organic compounds consisting of carbon, hydrogen and oxygen. They are present in all cellular organisms. The simple carbohydrates, known as monosaccharides, contain the three component elements C, H and O of which H and O are in the same ratio as [...]
