| Lysozyme activity | Observed in tears and saliva | | Connie Jamieson | 3/1/2012 | | Abstract Lysozyme is an enzyme found in both tears and saliva. Each time we blink our eyes‚ our eyelids wash tears over the surface of our eyes. In addition‚ our mouth is continually producing saliva. A spectrophotometer set to 450nm was used to measure the effect of lysozyme on bacteria. The absorbance or optical density was measured for each sample at specific times with a total measuring time of

Effects of Wavelength and Light Intensity on Photosynthetic Activity ABSTRACT The photosynthetic process of eukaryotes revolves around chlorophyll‚ the substance that give plants their green color. Plants convert light energy into chemical energy by means of photosynthesis. This experiment tests the reaction rates of a chloroplast suspension against variables of wavelengths and light intensity. Both a control and an experimental cuvette were exposed to a range of 450 to 750nm of light and varying

Evaluation of existing off/online marketing activities Marketing activities refers to how to handle the marketing mix‚ which is‚ price‚ place‚ product‚ promotion in order to be able to market the product successfully. Tracking and measuring the performance of integrated marketing campaigns is very important in being able to work out the returns on marketing investments and whether or not the campaigns achieved its objectives and had any effect on customer or target audience. Therefore by evaluating

is the temperature at which water changes phase from a liquid to a solid or vice versa. The freezing point describes the liquid to solid transition while the melting point is the temperature at which water goes from a solid (ice) to liquid water. In theory‚ the two temperatures would be the same‚ but liquids can be super cooled beyond their freezing points so that they don’t solidify until well below freezing point. Ordinarily the freezing point of water is 0° C or 32° F. The temperature may be lower

The Activity of a Protease (Trypsin) Introduction Enzymes catalyze reactions by creating alternate reaction mechanisms whose transition states are more thermodynamically stable than uncatalyzed reactions (Berg et al.‚ 2002; UBC Department of Microbiology and Immunology‚ 2006). Increased thermodynamic stability in these transition states reduces the energy of activation‚ the minimum amount of energy input a chemical system requires for a reaction to occur (UBC Department of Microbiology

the 200mL beaker started with an average temperature of 43.5oC it then gradually fell to 41oC after 45 seconds‚ then rapidly decreased in temperature by 2oC every 15 seconds. At the 90 second period it decreased by 4oC from 35.5oC to 31.5oC it then steadied out falling by 1oC per 15 seconds until the 120 second stop mark. For the 500mL beaker the temperature difference between the 15 second intervals were very different being more gradual with the temperature on average falling from 1 – 1.25oC per
