what are the types of Isotopes in biology and Radioactivity isotopes

what are isotopes

Isotopes in biology The Phenomenon of natural radioactivity was accidentally discovered by the french scientist henry becquerel. When he found that crystals of potassium uranyl sulphate spontaneously emitted a radiation which could blacken photographic plate. Subsequently other naturally radioactive elements like radium, thorium and radon were discovered. Isotopes: the word isotope is derived from the … Read more

factors that effecting enzymes activity

 Factors affecting enzyme activity:- The contact between enzyme and substrate is the most essential for enzyme activity. Concentration of enzymes:- As the concentration of enzymes increases the velocity of the reaction proportionally increases. Concentration of substrate:- In the substrate concentration gradually increases the velocity of the enzyme reactions. A rectangular hyperbola is obtained when velocity … Read more
