Investigating the effect of pH on the activity of the enzyme catalase. Introduction Hydrogen peroxide (H2O2) is a very pale blue liquid which appears colourless in a dilute solution‚ slightly more viscous than water. It is a weak acid. It has strong oxidizing properties and is therefore a powerful bleaching agent that is mostly used for bleaching paper. Catalase is a common enzyme found in all living organisms. Its functions include the conversion of Hydrogen Peroxide‚ a powerful and potentially

Pascal 10x3. Investigating How Different Concentration Effects The Rate Of Reaction. Strategy A Possible Factors * Source of catalase * Concentration * Surface Area of enzyme * Concentration of enzyme * pH * Temperature Chosen Factor We chose to investigate the concentration of enzyme as we had previously investigated the optimum temperature for catalase in the preliminary investigation. Concentration of enzyme is also fairly easy to investigate‚ as you need

Title of investigation: The effect of solute concentration on osmosis in potatoes. Research question: What is the solute concentration of a potato? Hypothesis: Osmosis is the movement of water across the membrane from an area of high concentration to an area of low concentration. The osmosis continues until the solute concentrations are equal in both areas. In this experiment‚ we put pieces of potatoes into test tubes with sugar solutions of different concentrations and leave them there over night

Enzyme Catalase Activity in Reaction with the Substrate Hydrogen Peroxide Abstract We performed these experiments to observe the effects of enzymes on the rate of reactions. We tested and compared the activity of the enzyme catalase on the substrate H2O2 in various states and percentages‚ and observed the absorption values of the enzyme-substrate relationship at different concentrations. Our results show that the more substrate available‚ the quicker the reaction will happen except in one test

responsible for making the pillbug habitat‚ taking them in and out of the habitat for our experiment‚ setting up the experiment setups for testing‚ and timing the experiment. In my opinion‚ I contributed a lot in my group. I did a majority of the lab proposal‚ and a substantial amount in the lab report. I was always the one getting up to gather our materials and pillbugs from the bins and making sure that our experiment was going as smoothly as intended. From this project‚

Method I generally followed most of my plan for the experiments‚ but to improve accuracy and reliability‚ I made one change. In my plan‚ I said that I was going to use 20cm³ of starch for each experiment. However‚ in my actual experiment I used 40cm³ of starch. This is because I thought I might not have had enough solution if I only used 20cm³ of starch. If this was the case‚ then I would have to stop the experiment half way through‚ which would have prevented me from obtaining accurate results

From the experiment‚ the blood glucose concentration for Patient A is 5.6 mmol/L(Refer to Table 1). The blood glucose level for Patient A is normal as 5.6mmol/L is in the normal range. Urine sample from Patient A was tested and it is shown that there was no glucose and sodium present. The results showed that Patient A is healthy and could act as a control in this investigation. Secondly‚ patient B is suspected to suffer from diabetes mellitus. The blood glucose concentration for Patient B is 111mmol/L

Experiment 3: Stochastic Events • Consider the same population of butterflies is in the path of a hurricane. All survive‚ but 10 are blown to a new location. These 10 start a new population; their progeny will reflect the founder’s gene pool. This is known as the founder effect. Materials Beaker #1 Beaker #2 Beaker #3 Questions 1. What observations can you make regarding the gene pool and gene frequency of the founding individuals? 2. Do these results vary between the populations founded by
