Chirag Patel Biology 157 Determining the Effect of Varying Substrate Concentration Question: How does concentration of potatoes affect the amount of oxygen produced with hydrogen peroxide and potatoes (enzymes)? Introduction The enzyme used for this experiment is Catalase. Catalase is inside mostly any living organism which uses oxygen. Its job is to break down hydrogen peroxide‚ into oxygen and water. (Formula) 2H2O2 ---> 2H2O + O2 (lab manual). There are limiting factors which if altered

Emily Rasichanh Essay 4 Professor Marshall November 9th‚ 2012 How was it like at Auschwitz’s Concentration Camp? “Why is it that nobody cries out‚ nobody spits in their faces‚ nobody jumps at their throats? We doff our caps to the S.S. men returning from the little wood; if our name is called we obediently go with them to die‚ and—we do nothing. We starve‚ we are drenched by rain‚ and we are torn from our families. What is this mystery? This strange power of one man over another? This

How fast is your reaction? Part 1 – How temperature affect the rate of reaction Chemical equation Magnesium + hydrochloric acid → magnesium chloride + hydrogen Mg + 2HCL → MgCl2 + H2 Graph Conclusion and questions 1. What factors/variables did you keep the same in this experiment? * We kept the same volume of hydrochloric acid (10 cm3) and the magnesium ribbon (5cm) because that way we could get a fair test experiment. We also repeated

HCL Technologies Case Study In this Assessment I will use the HCL case study to analyze the trends and economic forces that impact innovation and change in the global markets of HCL Technologies. Analyze the ways that Nayar applied theory to change organizational structure‚ culture‚ and processes to support and sustain innovation in light of the changing global markets. Lastly‚ I will Analyze Nayar’s leadership in relation to the effectiveness of general management planning and decision making

enzyme concentration Enzymes are proteins that act as catalysts and they are the most important type of protein. My aim in this experiment was to investigate the effect of enzyme concentration on the rate of an enzyme (protease) – catalyzed reaction ‚ catalysts speed up chemical reactions . My hypothesis is that the rate as reaction will increase as the concentration of protease in the solution increases so it will take less time for the reaction to take place . This is because the rate of an

IS Concentration and Career Analysis Introduction Coming from a family that owns a small business‚ I decided to pursue a degree in business administration with concentration in management and marketing. By the time I graduated from college‚ I realized how important it is to implement information technology into a small business like ours. Our competitors have created online shopping websites which result in increasing sales and expanding territories. It would be cost insufficient for us to hire

Substrate Concentrations (3%‚ 1% and 0.3%) as which one was the fastest to react‚ I hypothesized that the reaction would occur the fastest with the 3% hydrogen peroxide (the highest amount of concentration) because the higher the concentration the more faster the reaction occurs and helps produce or break up the enzyme. After testing all three of my substrate concentrations with 10 trials each‚ my data showed (first graph) that the 3% substrate concentration had the fastest average rate at 0.19 of

World War II brought up many ethical issues. One of these was the ethical treatment of prisoners. As the Allied forces pushed into Nazi territory and came upon the concentration camps‚ the true horrors of World War II were seen. Dachau Concentration Camp in Southeast Germany‚ was the first of the concentration camps built by the Nationalsozialistische Deutsche Arbeiterpartei ‚ commonly referred to as the Nazi party. At the camp‚ the prisoners were forced to do hard labor and were unjustly executed

respiration is defined as an enzyme mediated process in which organic compounds such as glucose is broken down into simpler products with the release of energy (Duka‚ Diaz and Villa‚ 2009). It is a series of metabolic processes and oxidation-reduction reactions. Oxidation of substrates‚ such as glucose‚ is a fundamental part of cellular respiration (Mader‚ 2009). As a catabolic process‚ it may or may not require the presence of oxygen. The process that requires oxygen is called aerobic respiration while

Serum creatinine concentration shows a relationship with GFR‚ making it specific‚ but not a sensitive measure of GFR. The creatinine pool is influenced by nutritional state‚ hepatic disease gender‚ ethnicity‚ protein intake‚ and age (Slack et al.‚ 2010). In liver cirrhosis‚ the decrease in serum creatinine is due to a 50% reduction in hepatic production of creatine; increases in volume of distribution due to accumulation of extracellular fluid‚ ascites‚ edema‚ loss of muscle mass and malnutrition
