to be of any usefulness to an organism. Although in organisms‚ it is not necessary for the reactions to be at maximum rate at all times. Enzymes interact with other molecules to produce a stable system in which the products are made when they are needed in the exact amount. An enzyme lowers the activation energy of a reaction so its easier to proceed. Enzymes are specific to which substrates it binds with to the active site.(AS biology‚ 2008). There is a lock and key hypothesis‚ as shown in diagram

In depth analysis of light bulb can be an enriching experience. Cited by many as the single most important influence on post modern micro eco compartmentalism‚ it is yet to receive proper recognition for laying the foundations of democracy.

Of course‚ we live in an imperfect world and not all surfaces are smooth. When light strikes a rough surface‚ incoming light rays reflect at all sorts of angles because the surface is uneven. This scattering occurs in many of the objects we encounter every day. The surface of paper is a good example. You can see just how rough it is if you peer at it under a microscope. When light hits paper‚ the waves are reflected in all directions. This is what makes paper so incredibly useful -- you can read
