College General Biology I Enzymes‚ test for effect of pH on catalase activity Purpose The main purpose of this experiment was to learn about enzymes and how to test for the effect of pH on catalase activity and to be able to tell if a reaction is an exergonic or endergonic process. Introduction Enzymes are made from amino acids‚ which are made from proteins. In order to make an enzyme‚ hundreds of amino acids are strung together in a very specific and unique order and eventually is folded

was to find the relationship between temperature and the enzyme activity of amylase. This was achieved by attaining amylase enzyme‚ starch solution and potassium iodide (determines if enzymes hydrolyses the starch solution)‚ water bath and a hot plate. The temperatures used for this experiment were room temperature‚ 37oC‚ 60oC‚ 80oC‚ and 90oC. The hypothesis developed was that as the temperature increased‚ so will enzyme activity. Therefore‚ the ability of the enzyme to break down the starch

04 November 2013 The Effects Environmental Temperature and pH have on the Activity of Porcine Pancreatic Amylase Introduction There are many types of enzymes and each has a specific job. Enzymes are particular types of proteins that help to speed up some reactions‚ such as reactants going to products. One of them is the amylase enzyme. Amylases are found in saliva‚ and pancreatic secretions of the small intestine. The function of amylase is to break down big molecules of starch into small molecules

Investigation Into The Effect Of PH On The Activity Of Potato Tissue Catalase Aim The aim of my investigation is to see how pH affects the activity of potato tissue catalase‚ during the decomposition of hydrogen peroxide to produce water and oxygen. Catalase + 2H2O2 Catalase + 2H2O +O2 Catalase + Hydrogen Peroxide Catalase + Water + Oxygen Independent Variable The independent variable in this investigation is pH. Each individual enzyme has it’s own pH characteristic. This

The human blood buffer response to increased amounts of acids and bases was determined by titration of a 25.00 mL sample of H2PO4 buffer solution with 0.1 M HCl and 0.1 M NaOH. The volume of 0.1 M HCl is about double of the amount 0.1 M NaOH used to lower/raise the pH of a blood buffer. In this experiment‚ HCl (a strong acid) and NaOH (a strong base) are used as examples of strong acids/bases‚ and the titration with H2PO4 shows the effect on a buffer solution. The assumption was the addition

! Affect of pH on Porcine Pancreatic Alpha-Amylase Activity Introduction Proteins function in a variety of different ways‚ and one of their fundamental tasks is to act as enzymes. Enzymes are extremely important in controlling reaction speed (by initiating and regulating biological activity)‚ cell communication‚ and growth. One particularly significant enzyme is amylase‚ which catalyzes the hydrolysis of alpha glycosidic linkages of amylose‚ starch components‚ and other oligosaccharides (Qian

A buffer stock scheme is a form of government intervention designed to stabilize price. Governments apply buffer stock schemes to unstable markets‚ such as agriculture and commodities‚ where the ability and willingness of producers to produce fluctuates sharply. A buffer stock scheme stabilizes the price of a good by setting a ceiling/maximum and floor/minimum price for a good‚ e.g. rice. (Fig. 1). Price Band for Rice (Fig. 1) P S pmax

A buffer stock scheme (commonly implemented as intervention storage‚ the "ever-normal granary") is an attempt to use commodity storage for the purposes of stabilising prices in an entire economy or‚ more commonly‚ an individual (commodity) market.[1] Specifically‚ commodities are bought when there is a surplus in the economy‚ stored‚ and are then sold from these stores when there are economic shortages in the economy.[1] Their usefulnHistory Many agricultural schemes have been implemented over

Experiment 3 : Preparation of Solutions and Buffers Objectives : 1. To study and understand the principle theory and formula of preparation of buffer and solution. 2. To learn the methods of buffer and solution preparation. 3. To focus on concentration units of molarity‚ percentage of concentration‚ and dilution of solution. Introduction : When a substance‚ called a solute‚ is dissolved in another substance‚ called the solvent‚ a solution is formed. A solution is known as a homogeneous

Enzymatic activity of Human saliva (Salivary amylase) against Temperature Proponent: Ian Angelo P. Dela Cruz BS-Biology 1-3 Prof. McJervis S. Villaruel Professor – BIOL2015(Lab) ABSTRACT This report entitled “Enzymatic activity of Human saliva (Salivary amylase) against temperature” aims to know and observe the enzyme activity of the human saliva. The research only included the use of starch-agar as the medium to observe enzyme activity during the experiment. Five starch-agar
