POTATO INTO BATTERY Abstract a.Purpose To lessen the consume of electric charge b. Procedure We insert copper and zinc electrodes in to the potato‚ close but not touching each other. We use Clip leads to connect our electrodes to the Multimeter to measure voltage between two electrodes or current passing through the multimeter. For this experiment we used a galvanized nail for our Zinc electrode. c. Result It did go well and the potato did give voltage to the equipment (clock) However‚ the

Effects of Temperature on Enzyme Biology Introduction In order to understand the activity of enzymes at different temperatures the ability of the enzyme to function can be measured. This is important in many applications such as Polymerase Chain Reaction for forensics as well as genetics research where manipulation of temperature-dependent enzymes allows for replication of DNA segments. Bennett states‚ “when the energy - measured

Procedures for Part A: 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

Background Information Part 1 In the first part of the enzyme lab‚ we mixed a substrate and an indicator with an enzyme. There was also a neutral buffer in each of the chemical mixtures. The neutral buffer regulated the pH to around 7. We got a color palette and once we mixed each together‚ we observed and saw a change in the color of the substance. The darker and more brown the substance got‚ the more oxygen produced by the reaction. Our results showed that amount of oxygen produced increased

Chapter 1 By: Ciara Rafferty “You see I think everything’s terrible anyhow‚” she went on in a convinced way. “Everybody thinks so—the most advanced people. And I know. I’vebeen everywhere and seen everything and done everything.” Her eyes flashed around her in a defiant way‚ rather like Tom’s‚ and she laughed with thrilling scorn. “Sophisticated—God I’m sophisticated!” (21). This passage perfectly depicts the unhappiness that Daisy experiences from day to day. The life that she had

May 1‚ 2013 Enzymes as Drug Targets Enzymes are defined as any of numerous proteins produced in living cells that accelerate or catalyze the metabolic processes of an organism. Enzymes are usually very selective in the molecules that they act upon‚ called substrates‚ often reacting with only a single substrate. The substrate binds to the enzyme at a location called the active site just before the reaction catalyzed by the enzyme takes place. Enzymes can speed up chemical reactions by up to

3/1/2013 5) In response to the movie "Citizen Kane" one of the reason this film is considered one of the greatest produced is because of the many events in American History it alludes to‚ such as Yellow Journalism. Yellow Journalism was predomintaley seen throughout the 1880’s to the 1900s ‚ it was employed as a business‚ which caused editors to invent many stories that weren’t true. During this time period many newspapers were very intrested in catching the public’s attention rather than promoting

Enzyme Lab Daniyal Abdali (Rachel Lee) (Sarina Dolch) SBI 3UI Mr. Vrabec October 20‚ 2009 Test #1 * Add a small piece of cracker in test tube #1 and add Lugol’s solution. Observation #1 * The cracker turned a black colour when the Lugol’s solution was added to it. This was a positive result‚ meaning that the cracker contains starch. Test #2 * Add a bigger piece of cracker in test tube #2‚ add 5 mL of Benedict’s solution‚ place in a boiling water bath‚ and record observations
