The smaller valve of km suggest that the affinity of the enzymes is higher. The results from the graph showing the amount of maltose released by the action of α-amylase in each tube show that as the starch concentration increase the kinetic energy speeds up. The starch concentration of 0.28%(w/v) has shown that as the maximum time measured is met the maltose concentration 1.12mM showing that maximum activity occurred at this point. A study conducted by Enemchukwu et al., (2013) into α-amylase enzyme samples from one hundred healthy adult smokers and fifty non smokers. This experiment showed the effects of temperature, pH and substrate concentration.

The study was composed of four test groups; increase of Calcium, increase of Vitamin D, increase of both nutrients, and lastly the control group. These groups were made up of weight matched male four week old mice, they were “randomly assigned to the experimental high fat diets contain 60% energy as fat (Sergeev & Song, 2014, p.

[Page 5])” According to the article “the results reported supported the hypothesis that high Vitamin D and Calcium intakes reduce diet induced obesity by increasing Calcium mediated apoptosis in adipose tissue cia activation of the Calcium calpain caspase dependent pathway and indicate that targeting this pathway with Vitamin D and Calcium supplementation can represent and effective and affordable approach to the prevention and treatment of obesity (Sergeev & Song, 2014, p. [Page 6]).” Works Cited Sergeev, I. N. and Song, Q. (2014), High vitamin D and calcium intakes reduce diet-induced obesity in mice by increasing adipose tissue apoptosis. Mol.

Furthermore, gut microbiota have implications on host physiology, particularly adiposity. A paper by Le Chatelier et al. (2013) showed that microbiota composition varied between lean and obese individuals. In a study on mice by Turnbaugh et al. (2006), the microbiome of obese mice exhibited an increased capacity for energy harvest and transfer of the microbiota to non-obese mice increased their mean fat body weight, suggesting that a change in gut microbiota can induce obesity.
Lab Report Comparing Oxygen Consumption Rates in Different Mammalian Subclasses The purpose in experimenting with computer simulations was to compare oxygen consumption rates in different mammalian subclasses. We compared monotremes, marsupials, and placental mammals at both warm and cold temperatures. The results supported our hypothesis that when temperature increased, metabolic rate decreased. This was also supported using a student's t-test. We also found that placental mammals had the highest oxygen consumption rates and marsupials had the lowest.

Taking principal component composite scores ranking into account, level 2 was optimum. Factor D’ optimum was level 3 for the 1st and 3rd principal component, which was same with principal component composite scores ranking. So the optimum combination of compound feed additives for transport stress resistance was A1B1C2D3. 4. Conclusion Testing results about glucose, enzymes, cytokines and HSP70 in serum showed that rats housed under 22±1.0 ℃ were placed in shaking table with shaker speed 160 r/min and duration 2 hours could be used to simulate the transport stress.
