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

The Effect of Concentration‚ pH and Temperature on Enzyme Activity Biology For Majors October 4‚ 2012 Abstract We examined the reaction an enzyme has when its concentration‚ pH and temperature are altered. In order to do this‚ we added different levels of pH into different test tubes with the enzyme (sucrose)‚ and substrate (sucrose)‚ and we then inverted the tube. The higher pH produced more enzyme activity. Temperature effects enzyme activity by decreasing its stability when the temperature

Total CO2 Evolved by Different Concentrations of Convollaria roots. Actual values are the graduated pipette readings. For CO2 evolved values‚ subtract the initial reading from the actual reading. This is the amount of CO2 accumulated over time. | Time (min) | Tube 1 | Tube 2 | Tube 3 | Tube 4 | | Actual | CO2 Evolved | Actual | CO2 Evolved | Actual | CO2 Evolved | Actual | CO2 Evolved | | (A) | (A-I) | (A) | (A-I) | (A) | (A-I) | (A) | (A-I) | Initial reading (I) | 0.05 | | 0

The result of mineral content of wheat flour and banana peels is tabulated in table (3) that shows the concentration of phosphorus in wheat flour was the highest (784mg/kg) followed by potassium‚ calcium‚ sodium‚ iron‚ manganese and zinc (427‚ 238‚ 151‚ 38.03‚ 5.72 and 3.19 mg/kg) respectively. In banana peels‚ the concentration of potassium was the highest (16303 mg/kg). The concentration of calcium‚ sodium‚ iron‚ manganese‚ zinc and phosphorus were (3321‚ 440‚ 1217‚ 54.73‚ 1.97 and 641 mg/kg)

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

find out the concentration of the sulphuric acid in my experiment. I will do this by titrating the sulphuric acid with sodium carbonate. H2SO4 + Na2CO3 à Na2SO4 + H2O + CO2 Acid + Alkali à Salt + Water + Carbon dioxide Ratio of sulphuric acid to sodium carbonate: H2SO4 : Na2CO3 1 : 1 Concentration of sulphuric acid: H2SO4 is approximately 0.05 - 0.15 moldm-3 The average concentration of the sulphuric acid is: 0.05 + 0.15 = 0.1 moldm-3 2 Concentration (moldm-3) = concentration (g dm-3) Molar

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

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
