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 discuss about the importance of ATP and other compounds of high energy potential. Living cells must perform some endergonic reactions; these are not only anabolic reactions like those already mentioned (biosynthesis of macro- molecules such as polysaccharides, proteins, nucleic acids), but also some reactions of transport, transmission, mechanical work, functioning of the nervous system, catabolic [...]
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, [...]
