Active transport uses energy (ATP) for the moving the molecules in and out of the cellular membranes and therefore remain active, while in passive transport the molecules do not use energy for their movements and so the name is given as passive. We all know that cell is the basic unit of life. It is responsible for all the activities that occur inside our body. But some specialized cells are assigned to do the specific task, which is essential for body growth and development. These cells … [Read more...]
Difference Between Introns and Exons
Introns or the intervening sequence are considered as the non-coding part of the genes, while the exons or the expressed sequence are known to be as the coding part for proteins of the genes. Introns are the common attribute found in the genes of the multicellular eukaryotes like humans, while exons are found in both prokaryotes and eukaryotes. The traditional method for the flow of biological information in the living being is that the DNA makes RNA and then RNA makes proteins. These methods … [Read more...]
Difference Between Absorption and Adsorption
Absorption is the process which takes place, when one substance enters the volume or bulk of another substance, while adsorption is the condition which occurs on the surface of the substrate. In the case of adsorption, there are the intermolecular forces, which make the molecules to hold each other, but in absorption, there is soaking of the liquid or gas by the solid rather any forces applied on molecules. Here we noticed that there is the common term used in both the words is the … [Read more...]
Difference Between Cellulose, Starch and Glycogen
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 below. We all are aware of the importance of carbohydrate, whether it is plants, animals (including humans), or … [Read more...]
Difference Between Endothermic and Exothermic Reactions
Such chemical reaction in which the energy is absorbed in the form of heat is known as the endothermic reaction, while such chemical reactions in which energy is released or evolved in the form of heat is known as the exothermic reaction. So the main difference between these terms lies in the form of energy used or released during any chemical reaction. Chemical reactions not only takes place in laboratories, they happen in ones day to day routines, in our body also. For instance melting of … [Read more...]
Difference Between Red blood cells (RBC) and White blood cells (WBC)
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
The fundamental difference between the two is - Osmosis is the movement of the solvent (water) from a region of higher concentrations to the region of lower concentration through a semipermeable membrane, to maintain the equilibrium. On the other hand, diffusion can be described as the movement of the molecules (solid, liquid or gases) from the region of higher concentration to the region of lower concentrations, but not through a semipermeable membrane. Both of this kind are the examples of … [Read more...]
Difference Between Inhalation and Exhalation
Inhalation is the process of taking in air containing oxygen, while exhalation is the process of giving out rich containing carbon dioxide. This is the basic process of breathing. Here one breath involves the one complete inhalation and exhalation. So breathing rate varies from person to person and different kind of activity they perform in a day. Though on an average, the breathing rate of an adult is 15-18 times a minute, however, it may increase up to 25 times per minute in case of heavy … [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...]
