Secondly, X-ray machines sometimes fail in diagnosing soft tissues, muscles damage and … [Read more...]

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...]

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...]

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...]
