One example of something that went well in the liver lab investigation was that each person in the group had the same roles (manager, bottle holder, chemical handler, and computer operator) between part one and part two. Another example of something that went well was that the program and technique used to find the data and graph of the results was the same between part one and part two. One example of something that did not go well in the lab investigation was that the amount of H₂O₂ and catalase

Enzymes activity plays an important role on living organisms. Its activity can be affected by different factors, including environmental and molecular elements. Enzyme inhibition by some molecules can be competitive or noncompetitive according to the binding mechanism. The aim of this study was to determine the type of inhibition occurred by the phenylthiourea (PTU) on the catechol oxidase enzyme. Different substrate concentrations, 0.5, 1, and 1.5 mL, and presence (1mL) and absent of PTU was analyzed

peptides that are seven to eight amino acids long by proteolysis, a type of chemical reaction. In order to enter the proteasome for degradation, proteins first need to be tagged by a small protein called ubiquitin. The ubiquitin is attached by an enzyme called ubiquitin ligase. After one ubiquitin is attached to the molecule, it sends a signal to other ubiquitin ligases to attach more ubiquitin proteins. Once enough ubiquitin has attached to the protein, the proteasome allows the protein to fasten

the peroxidase became affected within the testing environments. In terms of the enzyme concentration, both of the different conditions (double and half) resulted with the absorption readings at 470 nm to steadily increase over the course of 5 minutes. This result was caused because there were more enzymes present to react with the two substrates, hydrogen peroxide and guaiacol, therefore affecting the overall enzyme activity to become higher. Moving onto the temperature group, the results were a

Discussion: Average concentration of NaOH solution was 4.35 M. There are many sources of error in this experiment as we got some percentage differences in the two different trials. For the Trial 1 and Trial 2, the percentage difference is 3.7 % which is significant difference to be noted. This percentage difference could occur due to many reasons such as not measuring the KHP properly as we got 0.42 g for first trial and 0.4139 g for second trial of KHP for performing titration but it is more than

The enzyme tyrosinase catalyzes the production and synthesis of melanin, which is the pigment that causes discoloration or browning in foods influencing their taste, flavor, and texture (Zaidi 1). For the best performance of foods, industries and homes across the globe result to using preservation, freezing, and blanching to prevent the loss of quality and oxidation reactions that occur. I chose to experiment with the common white button mushroom, also known as Agaricus bisporus, due to my grandparents'

Biologi Kost og sundhed Helene og Kristoffer ”Uden mad og drikke duer helten ikke” Hvis Ikke kroppen får mad og drikke, kan den ikke fungere. En vigtig del af den daglige nærring er nærringsstoffer. Nærringsstoffer består af kemiske substanser, som vi finder i maden. Gennem den mad vi spiser optager vi de forskellige næringsstoffer så kroppen kan fungere optimalt. Kroppen har brug for alle de forskellige næringsstoffer dog i forskellig grad og mængde. Vi får energi fra de forskellige næringsstoffer

3.1 Summary The present study was conducted to determine the characteristics of the Antartic yeast Glaciozyma antarctica PI12. Our results indicated that G. antarctica PI12 required 48 hours to reach its mid-log phase, with a doubling time of 15.8 hours per generation. Our result also indicated that G. antarctica PI12 grew better under aerobic condition than anaerobic condition. G. antarctica PI12 was able to grow and proliferate at -5oC and -7oC for at least five months. The cells entered mid-log

Catalase, a heme containing enzyme, is found in tiny organs inside of cells called peroxisomes. Catalase is found all over the human body. When catalase turns alcohol into acetaldehyde the hydrogen which is released is bound to hydrogen peroxide molecules which then become water. Although catalase is active everywhere in the body, catalase is of particular interest to researchers because it metabolizes alcohol in the brain. The acetaldehyde released into the brain by the metabolism of alcohol by

Enzymes An enzyme is a protein molecule that helps to increase the rate in which chemical reactions occur. Recognizing an enzyme is very simple as they are named after a substrate with the suffix “ase” attached to the end. In terms of activation energy, an enzyme’s function is to decrease the amount of energy necessary for the reaction to take place. An enzyme inhibitor prevents that function from happening by binding to the enzyme. There are two different ways that enzyme inhibition can occur
