Patrick McCrystal Enzymes: Natural Catalysts Enzymes are catalytic proteins‚ meaning they speed up chemical reactions without beingused up or altered permanently in the process. Although various enzymes use different methods‚all accomplish catalysis by lowering the activation energy for the reaction‚ thus allowing it tooccur more easily. Enzymes have very specific shapes (conformations). Part of the conformationis the active site of the enzyme‚ where the actual catalysis occurs. The specific molecule

could not take it away. Whereas disc brakes were kept open to the wind passing. Since 1950’s the effort on pedal pressure to operate has been reduced due to the reason that the self-servo effect is caused by the motion of the car. This motion helps in pulling the brake shoe to touch the drum which helps to lower the pedal pressure. In early 1950’s the disk brakes were introduced in the market with higher price. In later 1950’s‚ after Chrysler developed the disc brake with assisted movement in the

Parts of the Computer & Their Functions Computers are assembled from several key components that make the computer functional‚ called hardware. While most computer users are primarily familiar with the monitor‚ keyboard‚ mouse‚ and other peripherals‚ the most important physical parts of a computer exist inside the case.
