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 absence of hemoglobin in them and comprises only 1% of the total volume of the blood. Red blood cells, White blood … [Read more...]
Difference Between Acid and Base
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 also play their significant role in another field of science. There are many definitions which differentiate the substances … [Read more...]
Difference Between Osmosis and Diffusion
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 diffusion, the membrane is not mandatory. It can spread the particles directly within the given medium. Osmosis … [Read more...]
Difference Between Glycolysis and Krebs (citric acid) Cycle
The main difference between glycolysis and Krebs cycle is: Glycolysis is the first step involved in the process of respiration and occurs in the cytoplasm of the cell. While Krebs Cycle is the second process of respiration which occurs in the mitochondria of the cell. Both are the process involved in respiration with the aim of fulfilling the energy requirement of the body. So Glycolysis is defined as the chain of the reactions, for the conversion of glucose (or glycogen) into pyruvate … [Read more...]
Difference Between Monosaccharide and Polysaccharide
A monosaccharide is the simplest form of sugars, containing single polyhydroxy aldehyde or ketone unit. Oligosaccharide consists of two or more units of monosaccharides, joined by glycosidic bonds.While the Polysaccharide consists of more than 20 or more units of monosaccharides, some may have hundreds or thousands of units. Monosaccharides, Oligosaccharides, and Polysaccharides are the main division of carbohydrates. The most basic part of one's diet is carbohydrates, as it is considered as … [Read more...]
Difference Between Haemoglobin and Myoglobin
The capability of the binding oxygen molecule, with the heme proteins, is what makes a difference in both the molecules. Haemoglobin is called as tetrameric hemoprotein, while myoglobin is called monomeric protein. Haemoglobin is found systematically all over the body, while myoglobin is found in muscles tissues only. Haemoglobin is made of protein and prosthetic group and is well known for carrying oxygen pigment. It is the most vital part to sustain life as it works in transporting oxygen … [Read more...]
Difference Between DNA and RNA
DNA and RNA are the two types of nucleic acids that act as the hereditary material to transfer genetic information from one generation to the next one. They store the inherited data in them, thus can be considered as the repositories for the genetic information. DNA (double-stranded) as a genetic transporter is present in almost all the higher eukaryotic organisms. Whereas RNA (single-stranded) as genetic material is found only in lower organisms like prokaryotes. Eukaryotes too have a large … [Read more...]
Difference Between Carbohydrates and Fats
Carbohydrates are soluble in water and are the most abundant dietary source of energy for all living organisms, whereas fats are insoluble in water but soluble in alcohol, ether, etc. Fats are also considered as a chief store of energy. Our body needs ample amount of energy to do 'work', which we get through macromolecules like carbohydrate and fats. Both of them provide energy to the body and are macronutrients which mean carbohydrates and fats are among top three sources of energy for a … [Read more...]
