Difference between Nitrate and Sulfate Respiration

The upcoming discussion will update you about the difference between nitrate and sulfate respiration. Difference # Nitrate Respiration: Nitrate respiration is typically carried out by some facultatively anaerobic bacteria, like Paracoccus denitrificans, Pseudomonas fluorescens, Ps. stutzeri, Ps. aeruginosa, Bacillus cereus, B. licheniformis, Thiobacillus denitrificans etc. All of them can also grow aerobically carrying out normal aerobic respiration, but they possess [...]

Heterotrophic Reactions Operating in Different Living Systems

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 [...]

Mechanism of Enzyme Reaction (With Equations)

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 [...]
