With reference to figure 1, the peak performance of catalase was at 30℃, which was the closest to its usual environment of body temperature at 37℃ (Buddies, 2012). Figure 1 depicts that at 0℃ the reaction rate was 3, whereas at 100℃ the reaction rate was 0, meaning that the catalase was denatured. Additionally, figure 1 demonstrates that reaction rate increases as temperature increases until catalase reaches its optimum temperature of 30℃, in which case the reaction rate decreases. Once again, the general trend displayed by this experiment is that reaction rate will increase until an enzyme reaches its optimal temperature, then the reaction rate will

The graphs have the same nature as one another. The gradient of both graphs are positive then negative. However the values on both graph differ. The volume of the froth at 10 degrees for the single data was 30 ml, while the volume for the average date at 10 degrees was 35.2 ml.
The 0.1% is the concentration amount. Just like temperature and pH, substrate concentration can speed the reaction only up to a certain limit. When we mixed pH 3 enzyme tube with substrate tube, we used 0.3 mL of hydrogen peroxide, but if we were to increase the amount, then the experiment would have been faster. Our
By leaving the acid and olefin in contact with no isobutane, polymerization occurred which increased acid consumption. After the shutdown, processing off-spec material also contributed to an increased acid consumption (see Figure 2, pg.4). Because of long residence times between the contactors and settlers, it will take time for the acid consumption to reduce to pre-shutdown levels. Acid spend strength has been higher than required for this period (see Figure 4, pg.5). Process Support recommends lowering the amount of fresh acid consumed to get closer to the spend target.
The mean HDL-cholesterol increased noticeably by 10-13%. No significant difference was noted in response to whether the drug was given in one dose or two. When the dose is increased from 5 to 120 mg, the pharmacological activity increases in a linear

To find chemical equilibrium, the following chemical equation is used in the experiment: Fe3+(aq) + SCN-(aq) FeSCN2+(aq). When iron (III) and thiocyanate react, thiocyanoiron (III) is produced. When the concentration of all ions at equilibrium are known, the equilibrium constant can be calculated by dividing the equilibrium concentration of the reactant by the equilibrium concentration of the products. In this experiment, four equilibrium systems containing different concentrations of three different ion types (Fe(NO3)3, KSCN-, and distilled water) are made and used to determine equilibrium concentrations.
The lowest aging index was found to be at 2% by weight of the binder. At this percentage, the decrease in long term aging index came out to be 30%. Hydrated lime was also tested with 67 - 22 binder. The greatest decrease in aging was found to be at 2% and 3% hydrated lime which is around 14%. The results can be seen in table 2.
KIDNEY AND TYPE 2 D.M Normal Glucose Homeostasis Normal Glucose Homeostasis reflects a Balance of glucose Production, absorption, and Excretion • A delicate balance between several regulatory processes maintains glucose within a narrow range of ~80-120 mg/d L throughout the day • Hormonal regulation – Insulin: glucose utilization and production – Glucagon: hepatic glucose production (together with insulin) • Organs – Liver: glucose production (via glucose formation and formation of glucose from glycogen) – Gastrointestinal tract: glucose absorption – Kidney: glucose production (via glucose formation), glucose re-absorption, and glucose excretion. (Chao E, et al. 2010) Role of the kidney in normal glucose homeostasis The kidneys play an important role in regulating glucose homeostasis through utilization of glucose, formation of glucose, and glucose re-absorption via sodium glucose co-transporters (S G L T) and glucose transporters. The renal threshold for glucose excretion (R T G) is increased in patients with type 2 diabetes (T 2 D M), possibly due to up regulation of S G L T 2 and SG
The beginning reaction that occurred at the pH level of 1 shows that the mean reaction rate was incredibly low, at 2 mL/minute. This then increased by 57 units once it reached its peak productivity of 59 mL/minute observed at pH 8. pH levels 6, 7, and 8 only varied between 1 and 2 mL/minute, which demonstrated similar rates of reaction. At pH 10, the reaction rate decreased considerably as it declined by 58 mL/minute, and maintained that productivity at pH 12.
As seen in the trend of both buffer, once the pH is lower than 3, the slope of dv/dpH increase drastically, showing the decreasing effects of the buffer. On the other hand, in the trend of both buffer on the right side of graph shows when NaOH is added, the change in pH is more drastic once past about pH 5. Although buffer 1 and buffer 2 shows a similar trend, the plot of buffer 1 is above the plot of buffer 2. The reason for this is that buffer 1 is made by an acid and base with an almost equal concentration. This makes buffer 1 a greater buffer compared to buffer 2. This is not true for Buffer 2 because the because NaOH was added to acetic acid to form acetate ions as conjugate base:
We tend to have a higher VO2max in younger individuals in comparison to someone that is older. For example the relative VO2 for the subject 23 years of age is 40.9 ml/kg/min while the subject 28 years of age had a slightly lower relative VO2 (39.8 ml/kg/min). The level and the frequency of exercise training will also influence the VO2 level obtained during this test. Individuals that perform high intensity exercise on a regular basis will have higher VO2 compared to untrained individual. For instance the 23 years old subject perform moderate level of exercise for 30 minutes/day, 3 times a week.
Experiment 13.1 Purpose: To determine the ∆H of a chemical reaction. Materials: 2 Styrofoam cups, Thermometer, Vinegar, Mass Scale, Measuring tablespoon and ½ teaspoon, Lye, and Safety goggles.
Osmosis is one of the most important regulators in the body. Osmosis regulates solvents through a semipermeable membrane from a less concentrated solution into a more concentrated one, creating equal concentration in and out of the cell. For the purpose of this laboratory a dialysis bag will be used to imitate the semipermeable membrane of a cell. The dialysis bags will be filled with different concentrations of sucrose and placed in distilled water to mimic osmosis. With the dependent variable being the mass of the bag and the independent variable being the sucrose.
