IgM is the first antibody to be produced in response to any antigen (foreign particle) invasion, while IgG is most abundantly found antibody in the human body. IgM is the largest immunoglobulin among all, with pentamer units and ten antigens binding site. IgG are responsible for humoral immunity and is a monomer unit which is lighter and smaller, with two antigen binding site. Due to the smaller size of this antibody, it is able to travel through the bloodstream. Our Immune system is one of … [Read more...]
Difference Between Prokaryotic Cells and Eukaryotic Cells
Prokaryotes are simple, small cells, whereas eukaryotic cells are complex, large structured and are present in trillions which can be single celled or multicellular. Prokaryotic cells do not have a well-defined nucleus but DNA molecule is located in the cell, termed as nucleoid, whereas eukaryotic cells have a well-defined nucleus, where genetic material is stored. Based on the structure and functions, cells are broadly classified as Prokaryotic cell and Eukaryotic cell Prokaryotic Cells are … [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...]
Difference Between Enzymes and Hormones
The enzyme is a catalyst which enhances the rate of reaction in the body whereas hormones are chemical messenger which provides the signal to the cell for performing various functions. Secondly, enzymes act on the site where they are produced while hormones act distantly from the cell where they are produced and travel through body fluid. Very few chances of occurring of diseases due to enzymes dysfunction, but hormonal dysfunction may give rise to life-long diseases; they are the main cause … [Read more...]
Difference Between Light Microscope and Electron Microscope
Magnification and resolving power is the key difference between Light Microscope and Electron Microscope which is about 1000X of the magnification with resolving power of 0.2um in Light Microscope and that of Electron Microscope is 10,00,000X magnification with resolving power of 0.5nm or even less. Microscopes are used to know the exact shape, function, and other features of microorganism, which are invisible from naked eyes though vital from biological aspects. The word microscope is taken … [Read more...]
