The Effects of pH‚ Temperature‚ Enzyme‚ and Substrate Concentrations on Benzoquinone Production BIOL 2051 June 10th 2013 Introduction Enzymes are the ultimate catalysts of living things. Enzymes are made of proteins which are structured and directed by amino acids chains. Enzymes attract and fit substrate molecules to an active site. The active site binds the substrate molecules covalently to enzyme forming an enzyme-substrate complex‚ which catalyzes

done‚ Cairo is a good place to go on a vacation because of all of its sights. Cairo has a very warm climate. If you want somewhere warm‚ Cairo is the place to go. Its year round average high temperature is 27° Celsius‚ which is 81° in Fahrenheit. The year round average low is 15° Celsius‚ which‚ in Fahrenheit‚ is 59°. Cairo is way different that Grafton‚ Wisconsin in many ways‚ such as transportation and time zones. You see‚ time zones have certain names and the time zone that Cairo is in is

Specific Heat: The specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius. The relationship between heat and temperature change is usually expressed in the form shown below where c is the specific heat. The relationship does not apply if a phase change is encountered‚ because the heat added or removed during a phase change does not change the temperature. Q=mcTDelta Abstract: In this experiment we are trying to determine the

prevents the ideal temperature of the thermometer from dropping. Our data shows this as well. When we used Jello‚ cornstarch‚ and aluminum foil‚ it kept our thermometer’s internal temperature 20 degrees higher than the ice’s temperature of 0 degrees Celsius. Although a lower temperature‚ it was the same results with negative feedback loops

Arenes The aromatic hydrocarbons also have the name arenes. They contain in their molecule one or more cycles made up from 6 carbon atoms. When the molecule is formed out of a single cycle‚ the hydrocarbons are mono nucleuses; when the molecule contains more than one cycle‚ the hydrocarbons are poly nucleuses. The simplest aromatic hydrocarbon‚ benzene‚ is compound out of just one such cycle; its formula is C6H6. The representation of benzene through a cycle of 6 carbon atoms with 3 double bounds

The purpose of Thermoregulation is to balance the thermal inputs and thermal losses in the body. It does this to maintain a relatively constant core body temperature of approximately 37 degrees celsius. In humans if our core body temperature reaches anywhere above 44 degrees celsius it will cause severe damage to our bodies that will result in death‚ which is one reason why the body needs to regulate its temperature. Protein functions are also reduced by the lowering of temperature. An

| 1.204 g | Mass of Acetanilide | 1.372 g | % Recovery | 65.07 % | % Composition of Pure Benzoic Acid | 46.74% | % Composition of Pure Acetanilide | 53.26 % | Melting Point of Benzoic Acid | 122-125 Degrees Celsius | Melting Point of Acetanilide | 113-116 Degrees Celsius | Results/Discussion: The percent recovery of acetanilide and benzoic acid did not yield 100 percent. A possible cause of this was due to the loss of benzoic acid through filtration‚ so minuscule amounts of acetanilide

tested environments were performed in room temperature‚ near boiling water‚ and nearly freezing. Test Tube 1: 2 ml of hydrogen peroxide added to liver at 22° degrees Celsius. Test Tube 2: 2 ml of hydrogen peroxide added to liver at 75° degrees Celsius. Test Tube 3: 2 ml of hydrogen peroxide added to liver at 3° degrees Celsius. Test tube 3 was kept in ice to regulate the cool temperature during the experiment. Test tube 2 was taken out of nearly boiling water to add the hydrogen peroxide for

Cameron White Principles of Chem Reactivity Dr. Singleton Comparative Analysis of McCloud’s Run and Indian Creek There are four important traits of any water stream in the natural world. The chemistry of the stream affects the ecosystem of the stream which includes people who utilize the water of the stream for various uses. Many factors play a part into the chemistry of the water such as the temperature‚ the pH‚ the turbidity‚ the conductivity‚ and the dissolved oxygen (A.K.A. DO) (1). Those

Water Crisis in India: Side Effect of Climate Change There is one very famous quote which says‚ “Water is life’s mater and matrix‚ mother and medium. There is no life without water”. This quote highlights the importance of water and its value in sustenance of life on earth. It has multiple uses and each of them supports life‚ directly or indirectly. Even though 75 percent of our Earth is covered with water‚ less than two percent is fresh water. To make the matters worse‚ only about 1% is available
