During this experiment‚ the temperature of tubes 5 and 6 showed that the color changed throughout the 20 minute time period. The catechol oxidase has to be at a certain temperature for it to react well. But based on our data when we put it at room temperature the reaction takes longer. If the temperature is too cold then all it does is slow the reaction as well‚ but when it is exposed into

INTRODUCTION The Gram Negative lab had two parts; the aim of the first part is to determine the concentration of gram negative bacteria in a water sample collected from a creek near Providence Road‚ Strickling. Gram negative bacteria have a cytoplasmic membrane‚ a thin peptidoglycan layer‚ and an additional outer membrane composed of phospholipids and lipopolysaccharides. Because gram negative bacteria have a relatively thin cell wall when compared to gram positive organisms‚ they are consequently

The word “depressed” and its multiple variations are thrown around casually in every day conversation. Often‚ one will say something like “that movie was so depressing.” Sometimes‚ a person who is feeling blue will describe his mood as depressed‚ but he does not actually have Clinical Depression. Clinical Depression‚ also called Major Depressive Disorder‚ is a serious‚ severe psychological disorder that affects the everyday lives of many individuals. It is actually quite common as “at least 10% of

the purpose of this experiment was to find out how an increasing substrate concentration influences the rate of an enzyme activity; we obtained data from recording the absorbance of the samples which contain the same amount of potato juice (enzyme oxidase) and different amount of catechol (substrate) while holding pH and temperature constant. Our findings illustrate that the rate of enzyme activity is only influenced by substrate concentration at low level of substrate concentration‚ and as substrate

Cyclobenzaprine and another similar muscle relaxant trazadone are structurally related to the first-generation tricyclic antidepressants such as imipramine. It therefore should not be used within 14 days of cessation of therapy with monoamine oxidase inhibitors (MAOIs). The exact mechanism of action for cyclobenzaprine is unknown. Current research appears to indicate that cyclobenzaprine acts on the locus coeruleus where it results in increased norepinephrine release‚ potentially through the

fermentation. Expected results showed that all bacteria should have been positive for this test. However‚ the test on P. vulgaris during the experiment was negative‚ defying expected results. The oxidase test was used to test for the presence of cytochrome c in the unknown. The unknown was shown to be oxidase negative which matches with the results for E. aerogenes. The results for P. aeruginosa were positive‚ making this bacteria less likely to be the unknown. The results for P. vulgaris were negative
