ABSTRACT: This lab allows us to observe the conversion of hydrogen peroxide (H2O2) into water and oxygen gas. An enzyme known as catalase facilitates this decomposition reaction. The catalase enzyme acts as catalysis‚ helping lower the energy needed to activate the reaction while the enzyme itself is not affected. Catalase is a digestive enzyme used to break down hydrogen peroxide‚ which is a normal byproduct of cellular respiration. The reaction could take place without the help of catalase‚ but

experiments are: Lactase Enzyme and Lactose. Lactase is a protein located in the human small intestine‚ while lactose is a term to define the sugar found in milk. Milk is a substance that contains nutrients necessary for our bodies‚ however‚ some people are unable to consume lactose related products‚ and so they are medically classified as Lactose Intolerants. The purpose of this experiment is to examine and illustrate the way that lactose gets affected by lactase enzyme whenever lactase is presented

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

a limited and extensive choice experiment in context to hotels. There were 661 participants‚ each chose one hotel and where then surveyed using six questions; three demographic and three in regards to difficulty‚ motivation and satisfaction using a 7-point Likert scale. The findings supported the hypothesis and were consistent with past research. Satisfaction and difficulty of choice showed a statistically significant difference with limited choice groups finding it less difficult and ended more

Bacterial Transformation Lab Report Backround: The plasmid pGLO contains an antibiotic-resistance gene‚ ampR‚ and the GFP gene is regulated by the control region of the ara operon. Ampicillin is an antibiotic that kills E. coli‚ so if E. coli‚ so if E. coli cells contain the ampicillin-resistance gene‚ the cells can survive exposure to ampicillin since the ampicillin-resistance gene encodes an enzyme that inactivates the antibiotic. Thus‚ transformed E. coli cells containing ampicillin-resistance

Web programming 1 Unit 7 discussion Assignment 1. What is the most popular server programming language? The most popular dynamic languages including Ruby‚ Python‚ PHP and JavaScript‚ which we can use as a server-side language through Node.js. Statically typed languages like Java‚ C and C++ are the most popular languages in CS programs‚ although Python has been gaining ground in recent years. To come up with more reality of what is the most popular server programming language let’s begin by dividing

Cognitive psychology PSYC2300 at the University of Newcastle. Design and stimuli The 3 x2 within participant design experiment consisted of two phases. The first phase was a study phase (60 trials) in which participants were asked to process words (5-7 letters in length) to different depths by answering (yes/ no) to various questions about the words (typeface (upper/lower)‚ phonemics and meaning)‚ all presented for 200ms. The second phase was a surprised memory phase (120 trials) that measured the

I also hypnotized that the enzyme is acidic on the pH scale because it exists in our small intestine and our small intestine uses acid to break down food. The result from the lab prove my hypothesis correct because lactase worked well at body temperature and it also worked well at pH of 4.5 to 5.5 mg/dl proving that lactase works best at an acidic pH number. The lab shows that the highest amount of glucose is made by temperatures close to body temperature. In our our lab‚ we found that at 35 °C 500

amylase lab‚ it was being tested if amylase‚ an enzyme found in saliva‚ would be denatured by being put in an acid or high temperatures. This lab is about denaturing amylase. It is tested by exposing it to pH and temperature changes. It is then mixed with Benedict’s solution‚ is a solution that changes color from blue to reddish brown when maltose is present. Amylase breaks starch into maltose‚ so is the amylase isn’t denatured‚ it should change colors. Amylase is an enzyme. Enzymes are a type
