Experimental Procedure: This lab follows the experimental procedure of the book as outline in the Mayo book on pages 133 and 134. However; the following modification were made to the procedure:…
Procedure: Filled each test tube with substances provided and subjected them to various conditions. These conditions included, heat, cold water, hot water, acid and basic additions and tested on litmus paper. The reactions were observed and documented at each step.…
i. What was not green about this experiment is that solvents were used in this experiment. This does not abide by GCP # 5 in that solvents should be not used. However since the amount of HCL needs to be stopped to be titrated, the use of acetone is necessary in quenching the reaction.…
-I had predicted that tube 3, which was put in boiling water, would have the most changes.…
1. Fill in the following tables with your observations. Note if the test is positive or negative for the enzyme. Also note the appearance of the colonies and/or media. This will include: the color of the medium immediately surrounding the colonies after addition of iodine on PDA plate, whether bubbles were observed or not in the catalase test, the color of the urea slant, the color of the citrate slant, and whether the rabbit plasma remained liquid or became solid due to clot formation, etc. After each observation note which results indicate production of the given enzymes and which results indicate non-production of the given enzyme by placing a “+” or “-“in the appropriate squares.…
The book “Their Eyes Were Watching God” by Zora Neale Hurston reflects gender issues, class status issues and relationship issues that existed in the African American community in early 1900s. The story revolves around Janie Crawford, an African American woman with a little bit of mixed ancestry. Abandoned by her mother, she is raised by her grandma who was a slave. Grandma or Nanny’s opinion about slavery was, "Honey, de white man is de ruler of everything as fur as Ah been able tuh find out” (14). Janie is searching for true love all her life. Janie is forced to marry an older guy at a young age because her grandma wanted security and shelter for Janie. Janie doesn't enjoy the marriage as she never felt loved like the way she thought what a marriage would feel like. The author says “She knew how marriage did not make love" (25).…
For Activity A, we first tested enzyme activity. First, we used an H2O2 syringe to transfer 10 mL of H2O2 into an unlabeled 60-mL cup. Then, we used a transfer pipet to add one mL of catalase solution into the unlabeled 60-mL cup that we put H2O2 in. After that, we observed the solution for one minute. Then we tested the effect of boiling on enzyme activity. First we used a transfer pipet to transfer 4 mL of catalase into a test tube. After that, we placed the test tube filled with catalase in a boiling water bath for five minutes. While we were waiting, we rinsed the unlabeled cup we used earlier when we tested enzyme activity. Then we used a H2O2 syringe to transfer 10 mL of H2O2 into the rinsed unlabeled cup. After five minutes, we transferred 1 mL of the boiling catalase into the unlabeled cup with H2O2 in it with an unused transfer pipet and observed the results. After testing the effect of boiling on enzyme activity, we tested for catalase in living tissue. First, we rinsed the unlabeled 60 mL cup we used earlier. Then, we used a scalpel to cut a small piece of liver. After that, we macerated the piece of liver with a glass rod. When the liver was macerated enough, we put it in a cup with 10 mL of H2O2, which was transferred into the cup with a H2O2 syringe. Lastly, we observed the cup.…
1) The purpose of this lab was to determine the rate of enzyme activity under variety of different conditions, such as, different amount of drops of enzymes and different temperature of water. The class measured the pressure in the test tube during the reaction of the substance with, 1.5 ml of H2O2, 1.5ml of H2O and different amounts of enzyme drops, to determine how much oxygen gas is produced during the reaction since the pressure of the test tube will get higher as more oxygen gas is accumulated during the reaction.…

MSG or monosodium glutamate is a sodium salt of glutamic acid which can be naturally found in many common foods that are rich in protein content such as dairy products, meat, vegetable and mother’s milk. In fact, our own bodies do produce glutamic acid via Krebs cycle during metabolizing food. Glutamate is the most abundant naturally occurring non-essential amino acid (Ninomiya, 1998) and it is a very common part of our diet. In the food industry, MSG is widely used as a flavor enhancer. It is responsible for cranking up the sensational umami flavors on our tongue to make bland food taste delicious. Umami can be described as a savory flavor and was named after the Japanese word “Umai” which means delicious (Ikeda, 2002). MSG was first discovered in 1908 by biochemist Kikunae Ikeda, the Japanese man who identified the natural flavor enhancing substance in seaweed. Today, MSG is added to recipe of many fast food and junk food to make them taste more wonderful. MSG is also used as a food additive in most soup, canned food, frozen dinner and crackers.…
To begin any experiment, you first need to set the temperature of your water bath, then add buffer and substrate to the reaction tube. Just as real experiments are conducted in a biochemistry lab, the enzyme should always be added to the tube…

The first Snowboard like invention was made in 1929 by Jack Burchett. He cut out a plank of plywood and secured it to his feet with a length of clothesline and some horse reins. Before the next step for the Snowboard was taken, it had to wait over 30 years until 1963. In this year Tom Sims, a Student in eighth grade, constructed what he called a "Ski Board", for a class project.…
Peaceful resistance to laws positively impacts a free society. In our world, civil disobedience is important in showing mass beliefs of all people. If any person doesn't agree with a law, they should have the right to peacefully resist the law as long as they accept the consequences. Resistance that is not peaceful is the problem in today's society and causes tension between people and the law. For example, Rosa Parks is a name that is important in history and will never be forgotten. “You must never be fearful about what you are doing when it is right.” - Rosa Parks. This is a thought that resonated in my mind since I learned her inspirational story. Society needs civil activists like Rosa Parks to make changes that are necessary today. Without…
