positive relationship between catalase concentration and the rate of reaction. This means when catalase concentration increases‚ the rate of reaction also increases. In other words‚ at 20% catalase concentration‚ the rate of reaction was only 4.220 mm/s while at 100% catalase concentration‚ the rate of reaction was 7.704 mm/s. This proves the positive correlation between catalase concentration and the rate of reaction. This occurs because as the enzyme concentration increases‚ there are more enzymes available

Materials & Methods Brook trout blood was used throughout our experiment as our erythrocyte suspension‚ which consisted of ten drops of fish blood in a test tube containing 10mL of 0.7% NaCl. Eleven other solutions‚ (erythritol‚ xylose‚ monacetin‚ diacetin‚ triacetin‚ urea‚ thiourea‚ glycerol‚ ethylene glycol‚ glucose and fructose) all isosmotic but not necessarily isotonic with the cytoplasm of the erythrocyte‚ were combined with a 0.2mL of well-mixed stock suspension were added to 0.27M of each

Auschwitz was a concentration camp established in 1940 by the Nazis. The Nazis sent the Jews and other "undesirable" people here to be used as slaves or to be killed. It was located in Oswiecim‚ Poland. There was no privacy when the captives had to go to the washroom. Buckets and toilets were lined up in rows‚ and the toilets were often broken and flooded with urine and feces. Although the prisoners were exhausted due to hard work‚ sleeping was difficult because the bunks were made out of wood. The

Effect of changes in substrate concentration on the reaction rate of an enzyme IB biology Internal Assessment 3/23/12 Research Question: Effect of changes in substrate concentration amount on the reaction rate of an enzyme Introduction: In this experiment‚ the substrate is hydrogen peroxide. The purpose of this investigation is to find out the relationship between the substrate concentration and the rate of reaction. Substrates are molecules that are acted upon by enzymes. For instance

Introduction: This project is one of the most famous electricity projects that can be performed successfully by most students in the age of 10 to 16. It helps students to learn about producing electrical energy using chemical energy. Since the same method is used to get energy from many fruits and chemicals‚ this project has many names. Following are some of the other names or titles for this project: |Fruit power or fruit battery

has different concentrations on either side. Permeable means "allows anything to pass through". Membranes in cells allow small molecules (water) to pass through‚ but prevent bigger ones from passing. This is called "selectively permeable". Take a look at the following animation; If a selectively permeable membrane separates the two solutions‚ water moves through it in both directions at the same time. However‚ more water leaves a dilute solution (high water concentration) and passes into
