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 [...]
In this notes we will discuss about:- 1. Nomenclature and Classification of Enzymes 2. Kinetics of Enzyme-Reactions 3. Enzyme Activity and Assay. Notes # Nomenclature and Classification of Enzymes: Before a scientific nomenclature of enzymes was developed, they were given trivial names, like pepsin, trypsin, rennin, ptyaline etc. Later, a more logical system of nomenclature was adopted by adding the [...]
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 [...]
