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 volume for froth at 20 degrees for the single data was 42 ml, while the volume for the average data was 40.5 ml.
Substrate concentration basically means the amount used for the substrate. The substrate in our experiment was 0.1% hydrogen peroxide. 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.
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.
A mean decrease in LDL-cholesterol of 43-45% and in triglycerides of 21-31% was shown by a dose of 40 mg per/day. 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 equilibrium concentrations are used to calculate the concentration that all of the components of the chemical equation are at equilibrium.
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
