Breathing is the biophysical process which involves the inhaling and exhaling of air through lungs, whereas respiration is the biochemical process which involves in generating the energy by breaking down the glucose which is further used by cells in various function. Breathing is distinct from respiration in many ways, though both are essential for living organisms. As discussed above the mechanism of breathing is associated with the respiratory organs like the nose, lungs, etc., while … [Read more...]
Difference Between Point and Frameshift Mutations
The changes in the single base or nucleotide in the nucleotide sequence and thus changing its complementary base also it is called as point mutations, while when there are insertions or deletions of more than one base pair in the nucleotide sequence it is known as frameshift mutations. Mutations can be defined as any kind of change in the nucleotide sequence or genetic code, which altering the gene structure as well as the amino acids and the proteins too. These mutations occur in the DNA … [Read more...]
Difference Between Mutation and Variation
The changes in the nucleotide sequence at the DNA level or in any one of the base pairs is known as mutation, while the genetic variation is how one individual of a species variate from another, variation can be due to changes in the nucleotide sequence like insertions, deletions, any genetic rearrangements or any environmental factors. We all are aware of the DNA, RNA which are said as the genetic material and consist of the codes or bases A, C, G and T, and their combinations make the … [Read more...]
Difference Between Covalent, Metallic and Ionic Bonds
Covalent bond occurs between the two non-metals, metallic bond occurs between two metals and the ionic bond occurs between the metal and the non-metal. Covalent bond involves the sharing of electrons, while metallic bonds have strong attractions and ionic bonds involve the transferring and accepting of electrons from the valence shell. The adhering property of an atom, in order to arrange themselves in a most stable pattern by filling their outermost electrons orbit. This association of atoms … [Read more...]
Difference Between Cation and Anion
We can divide the ions into two categories: cation and anion, based on the charge they bear. However, they both get generated from a neutral atom. The cations consist of more positively charged protons than that of negative electrons. And due to this extra positivity, they have a positive charge. In contrast, the anions are negatively charged as they possess more electrons than protons. The cations being positively charged, tend to move towards the negative electrode. Whereas, the positive … [Read more...]
Difference Between Active and Passive Transport
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
People frequently get confused between absorption and adsorption as they spell similar. But the mechanism by which two substances interact with each other clearly differentiates these two physio-chemical processes. On one hand, absorption refers to the distribution of one substance throughout the area of the second substance. In contrast, adsorption refers to the adhesion of one substance over the surface of the other one. In simple words, absorption takes the molecules, ions or particles … [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
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 than the product. Thus, in order to react, they absorb the energy from the environment. Due to this, the change in the … [Read more...]
