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, [...]
In this article we will discuss about the process of biosynthesis of steroids, explained with the help of suitable diagrams. Biosynthesis of Cholesterol: The main steps of the biosynthesis of cholesterol are diagrammatically represented in figure 5-22. The first reaction consists of the condensation of 2 molecules of acetyl-coA. It is the reverse of the reaction which takes place during [...]
In this article we will discuss about the process of biosynthesis of fatty acids, explained with the help of suitable diagrams. Synthesis of Saturated Fatty Acids: It must be pointed out at the very outset that the biosynthesis of fatty acids does not generally take place by the reactions — in the reverse direction — of β-oxidation; the latter are [...]
