    Title: The Effects of Substrate Concentration and Temperature on the Rate of Hydrolysis of the Enzyme Trypsin. Abstract: Quantitative measurements can relate both temperature and substrate concentration to the enzymatic activity of trypsin. By analyzing the data, it is suggested that at BAPNA concentrations below those corresponding to Vmax are rate limiting, as less active sights are available for adhesion. The values of Vmax and Km relate a temperate catalytic efficiency of trypsin. The temper...

    Introduction: Within each of our body cells are thousands of enzymes. These enzymes are proteins, or chains of amino acids that are responsible for chemical reactions. Enzymes are also called organic catalysts. A catalyst is a substance that speeds a chemical reaction without getting changed much itself. The catalyst well be using in this experiment is Hydrogen Peroxide or H 2 O 2. Objective: To demonstrate the activity of enzymes under different conditions. 3) Chicken liver (fresh, boiled, froz...

    1,607 words
    1. State the five assumptions of the Kinetic-Molecular Theory of gases. a) Gases consist of large numbers of tiny particles. These particles, usually molecules or atoms, typically occupy a volume about 1000 times larger than occupied by the same number of particles in the liquid or solid state. Thus molecules of gases are much further apart than those of liquids or solids. Most of the volume occupied by a gas is empty space. This accounts for the lower density of gases compared to liquids and so...

    Avogadro's number is the number 6. 0221367 x 10 ^ 23, commonly rounded to just three significant digits: 6. 02 x 10 ^ 23, and is the number of representative particles in a mole. Avogadro's number is commonly used to compute the quantities of substances involved in chemical reactions, called stoichiometry, and is one of the most important and versatile components of modern chemistry. Avogadro's number is named after the Italian physicist Amadeo Avogadro. Avogadro's number first came about when A...

    The first thing water reminds us of is the clear liquid in our water bottles. However, water is more than a normal substance. Water is the beginning and the continual of life on earth. Because of its many unique properties, water was able to start life on our planet. The simple structure of H 2 O is the source of all water's properties. With two hydrogen atoms sticking to an oxygen atom in a tetrahedron shape, water is considered as a polar molecule. Because oxygen is very electronegative, it pu...

    Purpose - The purpose of this lab is to use a chemical titration to measure and them calculate the rate of conversion of hydrogen peroxide (H 2 O 2) to water and oxygen gas using the enzyme catalase. Hypothesis - The rate of enzymatically-catalyzed reactions can be determined by taking time reactions at different time intervals. When the rates are plotted on a graph, the rate of the reaction is the slope of the linear portion of the curve. To determine a rate, any two points on the straight-line...

    Magnesium, symbol Mg, is a silvery white metallic element that is relatively un-reactive. In group 2 of the periodic table, magnesium is one of the alkaline earth metals. The atomic number of magnesium is 12. Properties and Occurrence The metal, first isolated by the British chemist Sir Humphry Davy in 1808, is obtained today chiefly by electrolysis of fused magnesium chloride. Magnesium is malleable and ductile when heated. With the exception of beryllium, it is the lightest metal that remains ...

    Acid rain pollution comes in various forms. Whether its toxic waste, CFCs, or sewage, they are all hazardous to the earth. These can deplete the earth and its inhabitants of resources, causing a harmful change. A product of pollution is acid rain. We shall see that acidification is harmful to all forms of life. Acid rain is any form of precipitation that is polluted by sulphur dioxide (SO 2), and nitrogen oxides (NOX). This acid precipitation can be in the form of rain, snow, sleet, fog, or clou...

  • Clean Air Act H 2 O
    1,801 words
    Acid rain is exactly what it suggests- rain that is acidic. The definition of 'acid rain' is rain with a pH of below 5. 6. Rain becomes acidic because of gases that dissolve in the rain. Approximately 70 % of acid rain is a result of dissolved sulfur dioxide (SO 2) which forms Sulfuric Acid. The remaining 30 % or so comes from various Nitrogen Oxides (mostly NO 2 and NO 3 which has collectedly adopted the mane Nox). There is also a small percentage of hydrochloric acid that makes up hydrochloric...

    AMass Spectrometer Mass Spectrometer A mass spectrometer produces charged particles (ions) from the chemical substances that are to be analyzed. The mass spectrometer then uses electric and magnetic fields to measure the mass (weight) of the charged particles. There are many different kinds of mass spectrometers, but all use magnetic and / or electric fields to exert forces on the charged particles produced from the chemicals to be analyzed. A basic mass spectrometer consists of three parts: 1. ...
