This experiment shows the effects of changing the pH level has on Catalase. As predicted‚ the farther away the pH levels got from the optimum pH (7.2)‚ the lower the reaction rate. At a pH of 7.2‚ the foam of the reaction measures 6cm. At a ph of 3 it measures 2.5 cm‚ at a pH of 5 it measures 2.75 cm‚ at ph 9 it measures 2.3 and at 11cm it measures 2cm. pH measures the hydrogen ion concentration of a substrate. By changing the pH of the catalase‚ the enzyme was denatured. Denaturing is the result

Construction of a Standard Curve for the Determination of Protein Concentration 09/13/12 PCB 3023-007 Results Figure1: Standard curve. This graph was constructed from the fixed amounts of Bovine Serum Albumin (BSA). Varying amounts of BSA at a concentration of .5µ/µl were mixed with the water and 1mL of coomassie dye. The equation y=0.0259x +0.0511 represents the best fit line for a data set taken from µg of protein equals two to ten µg. Optical density (OD) was surveyed using a Mach

Auschwitz concentration camp. Furthermore‚ it was three different types of camps that were brought together: concentration camp‚ extermination‚ and labor camp (“Auschwitz was the largest camp”). All three camps played a major part in the Nazi’s “final solution” (Berenbaum). There were also subcamps part of Auschwitz. In just two years‚ 44 subcamps were built (1942 to 1944). Auschwitz also had different leaders. The first of the three leaders who controlled all of the Auschwitz concentration camps was

The purpose of the experiment conducted was to observe if a higher concentration or lower concentration gradient would affect the diffusion rate of the iodine moving through the starch concentration. This was shown to be an accurate experiment as with a higher concentration gradient the diffusion that did occur happened a lot faster and diffused more efficiently compared to no iodine solution and just water. This is due to the molecular collisions speeding up the experiment in the time period given

permeable membrane through a process of diffusion. The movement of a solute through this membrane is called dialysis . Diffusion is a form of passive transport. It is the movement of molecules from areas of higher concentration to those of lower concentration‚ until there is an even concentration. This movement is random because it is a result of kinetic energy. Diffusion is a slow process‚ but there are many factors that will affect it’s rate. The rate of diffusion will vary depending on the size of the

Before I came to the concentration camp‚ it was easy to be with your family but I have been in the concentration came for almost 3 months. In the times I been in the camp‚ I met my best friend‚ Graciela. Ever since I been in the concentration camp‚ life has been hard for everyone. In the mornings‚ you are awakened by the kapos in the 4 in the morning where you must raise and find your shoes to work. If someone stole your shoes‚ the person who took them often means they are send to death

Internment Camps vs. Concentration Camps There were two types of camps during WWII‚ internment camps and concentration camps. They each were created in a different place‚ the United States‚ and Europe. They have many differences‚ but also some similarities. Internment camps were created in the United States. They were created for the purpose of containing Japanese-Americans. The United States became fearful after Pearl Harbor got attacked by Japan‚ so they created these camps. The camps were like

ENZYMES: BIOCATALYSIS IN ORGANIC SOLVENTS: FUNDAMENTALS ENZYMES IN ORGANIC SYNTHESIS 1. Enzymes catalyze a broad spectrum of reactions with high turnover numbers. Rate enhancements approach 1012 fold. 2. Enzymes may accept a wide range of substrates. 3. Enzymes are highly regio and stereoselective. 4. Enzyme reactions take place under mild conditions; this minimizes problems of isomerization and racemization. 5. Enzymatic processes are less hazardous and polluting than conventional chemistry-based

Research Paper Concentration Camps The years 1939-1942 marked the expansion of the concentration camps system. The concentration camps took in Jew prisoners for economic profit. The concentration camps also became sites for the mass murder of small targeted groups by the Nazi authorities. The concentration camps were a major role in the Holocaust‚ changing the lives of every Jew‚ leaving a horrible memory for those who did survive the concentration camps. The first concentration camp was camp
