Lab Report (Effect of concentration on enzyme activity) Biology Noor Alawadhi 11- KC Introduction: An Enzyme is a protein‚ which is capable of starting a chemical reaction‚ which involves the formation or breakage of chemical bonds. A substrate is the surface or material on or from which an organism lives‚ grows‚ or obtains its nourishment. In this case it is hydrogen peroxide. This lab report will be explaining the experiment held to understand the effects of the changes in the amount of

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

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

third reaction involves molecular iodine becoming a dark blue starch;I2(aq) + starch blue-black complex3. These three reactions react in a sequence. In any reaction the concentration is exponentially related to the rate of the reaction. The rate of the reaction is dependent on potassium iodate4. Therefore as the concentration increases‚ the rate of the reaction also increases. Since the rate of the reaction is inversely proportional to time‚ as the

which is liked by everyone. Carbon dioxide is responsible for the formation of froth on shaking the bottle. What we wanted to aim is the comparative and qualitative analysis of Coke‚ Sprite‚ and Royal. We tested the Comparative pH ‚ Carbon Acid and Glucose content of different soft drinks. Since soft drinks like Coca-Cola‚ Royal and Sprite are common beverages that Filipinos like to drink‚ It is usually sold in a lot of stores and markets. (This beverages taste sweet and has a tangy feeling in your

Determining the Unknown Concentration of NaHCO3 (aq) Through Titration Introduction Titration is the accurate addition of a titrant- solution in a burette- into a measured volume of a sample (Kessel‚ 2003). There are many different types of titration‚ such as acid-base reaction‚ redox reactions‚ precipitation reaction and more (Dohrman). In this lab an acid base titration will be explored. In an acid-base titration‚ the concentration of an acid or base is unknown and is determined by the adding

The Effect Of Substrate Concentration On The Activity Of The Enzyme Catalase A Level Biology Project Aims This is an experiment to examine how the concentration of the substrate hydrogen peroxide affects the rate of reaction of the enzyme catalase. Background Information Enzymes such as Catalase are protein molecules which are found in living cells. They are used to speed up specific reactions in the cells. They are all very specific as each enzyme just performs one particular reaction. Catalase

“Between 1.1 and 1.5 million people died at Auschwitz; 90 percent of them were Jews” (“Auschwitz”). Concentration camps were large numbers of people; mostly Jews enduring forced labor and mass executions. One of the concentration camps during the Holocaust was Auschwitz. Auschwitz-Birkenau had a unique design‚ a horrible daily life for those in it‚ and is greatly remembered for what happened at these camps at the end of the war. Nazi Germany set up camps with a specific design that would help them

The book “Night” and its topic of the concentration camps of Auschwitz and Buchenwald is very essential to the story. Wiesel describes these camps with great detail and emotion which got my attention and curiosity. With the research I have collected I learned that Auschwitz and Buchenwald were two major concentration camps to the Nazis in Germany that were mainly for either executing prisoners or forcing them to work in a variety of different fields. These two camps were known more as complexes
