These three polysaccharides differ in their glycosidic linkages and their functions too. Starting from the cellulose which is the monomer of beta glucose and is found in plant cell wall only. While Starch and Glycogen act as the carbohydrate reserve in plants and animals respectively. Though their chains have slight differences at the branching point, which is described … [Read more...] about Difference Between Cellulose, Starch and Glycogen

We classify the chemical reactions as endothermic or exothermic, depending on whether it is giving energy or taking energy. The endothermic reactions are when the system takes up the energy in the form of light or heat. In contrast, exothermic systems give up heat or light energy as the reaction proceeds. In endothermic processes, reactants possess lower potential energy … [Read more...] about Difference Between Endothermic and Exothermic Reactions

RBC or Red blood cells play the vital role in carrying oxygen to the tissues of different parts of the body. Conversely WBC or White blood cells help in the defense mechanism of the body by creating antibodies. Secondly, RBC contains hemoglobin, which gives the red color to the blood and occupies around 45-50% of the total volume of the blood, while WBC is colorless, due to the … [Read more...] about Difference Between Red blood cells (RBC) and White blood cells (WBC)

Such substances that donate their hydrogen ion (H+) (proton donor) and accepts the electron to another is called an acid. They have pH less than 7.0. But such substances that accept the proton and donate electron is called as the base. They have pH more than 7.0. Acids are sour, while bases are bitter. Acids and Bases are one of the most important parts of chemistry, but … [Read more...] about Difference Between Acid and Base

Osmosis and Diffusion both depict the movement of particles from higher concentration to lower concentration. However, osmosis is a type of diffusion that is limited to fluids. Whereas, diffusion is not restricted and is prevalent in solids, liquids and gases. The passage of the solvent molecules in osmosis occurs through a selectively permeable membrane. In contrast, for … [Read more...] about Difference Between Osmosis and Diffusion
