In this article we will discuss about the formation of ATP in anaerobic cells. We know that the formation of ATP in the respiratory chain is because it is the most common process in living organisms. The strict anaerobes, i.e. species which can live only in the absence of oxygen (in the ground or mud, for example) are comparatively rare. [...]
The following points highlight the three possibilities of the transformation of pyruvic acid. The possibilities are: 1. Production of Lactic Acid 2. Alcoholic Fermentation 3. Formation of α-Glycerophosphate and Glycerol. Possibility # 1. Production of Lactic Acid: In animals, in muscle cells (where anaerobiosis conditions often prevail when oxygen utilization is more rapid than its input in cells) or in [...]
In this article we will discuss about the inhibition of glycolysis by oxygen. Some controls, particularly hormonal, are carried out on glycolysis. We will examine here only the effect of oxygen known as the Pasteur effect because Pasteur was the first scientist to observe that in yeast, glucose was less rapidly consumed in aerobiosis than in anaerobiosis. In other words, [...]
