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 [...]
In this article we will learn about the formation of ATP in the respirator chain. Advantage of an Oxidation by Steps: Glucose or glucosyl equivalents, are our main source of energy; we will take them as example to illustrate the relations between cellular oxidations and ATP formation. But it must be said that other compounds can be a source of [...]
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 [...]
