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 photosynthetic cycle of reduction of Co2 into carbohydrates. The transformation of light energy into chemical energy results in the production of ATP and NADPH (see fig. 3-12). Our present knowledge of the metabolism of carbohydrates will enable us to study what is sometimes called the dark phase of photosynthesis, i.e. the series [...]
It was observed that pyruvic acid and lactic acid formed in the muscle during glycolysis can be reconverted into glucose (or glycogen) when energy is available (in aerobiosis) and one could wonder whether this neoglucogenesis (or gluconeogenesis, or neoglycogenesis) follows — in the reverse direction — the glycolytic path. In fact, among the reactions leading from glucose to pyruvic acid [...]
