Debbie Cao IB Chemistry 12 Pressure/Volume of Air Full Lab Write Up Introduction: According to Boyle’s Law‚ the volume of any given amount of gas held at a constant temperature varies inversely with the applied pressure. In other words‚ when the pressure increases the volume decreases. When pressure decreases‚ volume increases. This can be derived from the following equation: P1 V1=P2 V2 The common use of this equation is to predict how a change in pressure or volume will alter the

Rate of Enzyme Activity Justin Hunter G. Kim September 16‚ 2011 September 26‚ 2011 Abstract Catalase is a common enzyme found in nearly all living organisms that is frequently used by cells to rapidly catalyze the decomposition of hydrogen peroxide into less reactive oxygen and water molecules. Catalase is a protein that is most commonly found in the liver. The purpose of this experiment was to determine the effect that changes in temperature and pH have on the function of the enzyme catalase

Purpose: To find how pH and temperature levels affect the enzyme Background: Enzymes are a type of protein vital to sustaining life‚ it works with vitamins and minerals as a biological catalyst‚ which lowers the activation energy for a reaction to occur. Each individual type of enzyme does a specific job‚ and they do not die‚ they are reused. For example‚ catalase is an enzyme found in almost all living cells that will break down hydrogen peroxide and turn it into water and oxygen. The

that Fiat needs a partner? In an attempt to lower costs‚ most major automotive makers had set up factories in emerging markets such as China‚ India and South America. Because lower production costs were one incentive‚ experts also suggested that car makers could gain access to growing and fertile marketplaces that is the background for auto manufacture in India. The liberalization policies in 1991 opened up India to new import and export possibilities. To encourage investments‚ the government launched

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
