How Enzymes speed up the chemical reactions?
Enzymes are complex biological molecules which catalyze or greatly speeds up the rate at which a chemical reaction will occur. The key concept behind the speeding up of a chemical reaction by an enzyme is that it reduces the activation energy required for a reaction. In doing so, it speeds up the reaction. […]

What are Antitranspirants? How do they Reduce Water Loss in Plants?
Antitranspirants are the materials or chemicals which are capable of reducing the water loss from plant leaves. Almost 99 per cent of the water absorbed by the plant is lost in transpiration. Since water loss normally occurs through the stomatal pores in the leaves, anti-transpirants are usually foliar sprays. […]

From the beginning of time, humans have always been concerned about aging and have tried every bit of ability to defy this process. Many of us believe that aging results from the repetitive damage caused to our body cells due to radicals produced by the everyday metabolic activities that usually sustain our life also create “metabolic stress”. But, recent studies are proving this theory of aging wrong, and are saying that so called – “evil radicals” are not so evil. […]
