| 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

PART 1: PURCHASING ACTIVITIES In buying a PC for a specific purpose might be a little bit tricky‚ and during this process lot of factors that need to be consider before going to decide which one to go for‚ such as the price‚ usability‚ a good hard drive‚ the choice of processor directly affects your computer running speed‚ the size of your RAM. For me I will go for a desktop PC that is suitable for my needs and wants. These are the activities that I need to do in using my PC such as doing research

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

aim of this practical is to investigate the effect of exercise on heart rate and breathing rate. We will use a digital heart rate monitor strapped on our chest while we perform different levels of exercise. A digital watch is also provided which receives signals from the heart rate monitor and displays your current heart rate on the screen. To measure the breathing rate at different levels of exercise‚ we measure the breathing rate before physical activity by counting the number of breaths in 10 seconds

ACTIVITY ONE- Cell Transport Mechanisms and Permeability: Simulating Dialysis (Simple Diffusion) 1. Describe two variables that affect the rate of diffusion. Molecular weight affects the rate of diffusion because the bigger the size of the molecule the longer it will take to diffuse. Membrane size is another variable that affects the rate of diffusion because if the membrane’s pores are small it will take molecules longer to diffuse though it than if the pores were larger. Also‚ membrane thickness
