Experiment 10 – Enzymes Enzymes are proteins that act as catalysts for biological reactions. Enzymes‚ like all catalysts‚ speed up reactions without being used up themselves. They do this by lowering the activation energy of a reaction. All biochemical reactions are catalyzed by enzymes. Since enzymes are proteins‚ they can be denatured in a variety of ways‚ so they are most active under mild conditions. Most enzymes have optimum activity at a neutral pH and at body temperature. Enzymes are

In the Milgram experiment‚ a man picks random people to participate in an experiment. They believe that they are helping discover the roles of punishment on behavior. Although‚ this is not true. The participants themselves are the ones being analyzed. The experiment is to discover how far someone would obey an instruction of harming another person‚ despite personal conflict. The participant and an actor are places in a room and “get to choose” their roles of either teacher or learner‚ although the

The experiment was divided into three days to test the detoxification activity of Beetles grown on Mung and Black-eyed peas. In day 1 of part I‚ four beetles per group were chosen from each food sources for both ANAE and BNAE activity. In part I‚ the crude extract was obtained by the experimental design outlined in the lab manual (Course Supplement for Bio 101‚ p.68). Each member of the group took care of one Bean beetle crude extract. First‚ the sex was identified by the following instructions of

An Experiment on Soil Analysis Jacob Pitcher and Derrick Gillespie Chemistry Lab 112 Section 02 4/02/2013 Abstract A sample of soil was tested for possible contaminants and other information using a variety of techniques including moisture analysis‚ pH measurement‚ acid-base titration‚ chloride-ion electrode analysis‚ and flame testing. The sample had a greater concentration of chloride ions‚ no measurable CaCo3 ‚ and lower than standard moisture content. It was contaminated with KCl and

Matthew J. Hornsey; Louise Majkut; Deborah J. Terry and Blake M. McKimmie of the University of Queensland‚ performed two conformity experiments on university students. These experiments were done too measure the influence of group norms on student ’s attitudes. Experiment one involved 205 university students who rated themselves as being pro-gay law reform. The students were given numerous questions that asked them to rate the moral basis for their attitude‚ and what they believed society ’s

When you start you should have put the gummy bear in the water and the other in the plastic bag. The one in the water at the beginning of the experiment had a thickness of 9mm a width of 11mm and a height of 22mm and it had a total mass of 2.59grams and a total volume of around 2178 mm 3 The one in the plastic bag is going to be the constant It massed at 2.53 grams and had a height of 21mm a width of 12mm and thickness of 11mm and a total volume of 2772mm3 .

For this experiment‚ there were four onion bulbs labeled A‚ B‚ C‚ and D. Bulbs B‚ C‚ and D were each immersed in a different concentration of coffee. Bulb A acted as the control because it was not immersed in any concentration of coffee; instead‚ the onion roots grew in water. The following is a list‚ in order‚ of the concentration of caffeine bulbs B‚ C‚ and D were in: 0.1%‚ 0.3%‚ and 0.5%. Four test tubes were gathered to set up the experiment‚ each holding an onion bulb. After each day‚ every

decreased with time. This happened because the difference in water potential between the inside and the outside of the beetroot time decreased as the experiment proceeded. Osmosis occurred most in distilled water because this contained the highest water potential when compared with the other beakers. Five concentration were used in this experiment in an attempt to try to find the concentration of sugar inside the beetroot. If such concentration was used there would have been neither a decrease an

In order to conduct this experiment GIY Mushroom Material was obtained. All other materials were cleaned with rubbing alcohol‚ (70% Isopropyl Alcohol). Rubbing alcohol was used because mycelium needed a sterile environment (7). Everything was sprayed with alcohol including tables‚ gloves‚ mixing glass‚ and even the air. All materials used were cleaned because it protected the mycelium from competing with other organisms. Mold could have been floating in the air or bacteria from touching the face
