Monosaccharides are the simplest carbohydrates, which cannot be hydrolysed further. The general molecular formula is CnH2nOn. They are further subdivided into trioses, tetroses, pentoses, hexoses, and heptoses based on the number of carbon atoms present in them and into aldoses and ketoses based on the aldehyde or ketone group present.
Glycolysis occurs in all cells, and in some cells, it is the sole source of energy like brain cells, erythrocytes. Organelle: It occurs in cytoplasm of the cells. Steps Glycolysis is also called Embden Meyerhof pathway. In glycolysis, the breakdown of the six-carbon glucose into two molecules of the three-carbon pyruvate occurs in ten steps, Glycolysis…
Carbohydrates are classified into the following four major groups:
Carbohydrates are defined as polyhydroxy aldehydes or ketones. Carbohydrates are soluble in water and sweet in taste. Carbohydrates are one of the compounds largely present in nature. They perform the functions of storage and energy production and act as one of the membrane constituents.
Carbohydrates are relatively small molecules that are generally called as simple sugars (monosaccharides and disaccharides) as well as macromolecular substances (starch, glycogen, and celluloses). The word sugar emphasises the idea of energy in our minds. From the study of the structure–function relationship of biomolecules, it is apparent that each and every molecule differs structurally and also…
Figure 8.6 Outline of Glycolysis
It is an aqueous phase in which all the cytoplasmic organelles are suspended. Many proteins and numerous other solutes are found in cytoplasm. Some important metabolic processes that occur in the cytosol are glycolysis, gluconeogenesis, activation of amino acids, and fatty acid synthesis. The fluidity of cytosol is maintained by the process of hydration of…
Protoplasm is the living matter of the cell. The part of the protoplasm present inside the nucleus is nucleoplasm while the part surrounding the nucleus is called cytoplasm or cytosol.
INTRODUCTION Glycolysis was derived from the Greek words glykys, which means sweet, and lysis, which means splitting. In the process of glycolysis a molecule is catabolised in a series of reactions to yield two molecules of three-carbon compound called pyruvate. In the glycolysis pathway, a series of reaction takes place during which some of the energy is released…
