Enzyme Kinetics and Protein Determination: How Enzyme Catalase Concentration Affects Reaction Rate and Determining the Identity of Unknown Proteins through Absorbance By: Alexander Mak 7238991 Partner: Yasmin Ismail BIO2137 Section A7 Corrector: Chieu Anh Ta September 18‚ 2014 Introduction: The first lab’s primary objective is to observe the different reactions rates amongst the five different catalse concentrations of parsnip. The rate at which the enzyme catalyzes increases in

Abstract The enzyme peroxidase has been shown to break down H2O2. Enzymes are known to increase the rate at which a chemical reaction occurs. We looked at factors that affected the breakdown of hydrogen peroxide. These effects are the different temperatures and pH levels the enzymes were placed in. We found that the optimum‚ or best condition‚ temperature for the enzymes tested was about 22 degrees Celsius. The optimum pH level for the enzyme was 7. Introduction Enzymes are biochemical that catalyze

hydrogen ion concentration of a substrate. By changing the pH of the catalase‚ the enzyme was denatured. Denaturing is the result of altering the characteristics or properties of an enzyme by temperature‚ pH level‚ or substrate concentrate. As the optimal conditions of the enzyme are changed‚ bonds in the enzyme are broken and the enzyme unfolds at the tertiary and quaternary level. When this happens‚ the structure of the enzyme and active site is changed. With the change in the active site‚ the substrate

purpose of the first week experiment was to determine the effect of Nitrophenyl phosphate concentration‚ the substrate‚ on the enzyme‚ acid phosphatase‚ reaction. In an enzyme reaction‚ there is substrate that binds to the active site of the enzyme and product is the end result. The enzyme is the catalyst for the reaction which means that it speeds up the process. Without enzymes‚ the majority of reactions would not occur because the activation energy level would be unattainable. With this in mind‚ the

Biology Lab Report Research Question: Effects of pH on amylase activity Introduction: Amylase is an enzyme that is in human’s saliva as well as the pancreas. Enzymes are biological catalysts that speed up a chemical reaction. They break down complex molecules into simple ones. In this case‚ amylase converts starches (complex molecule) into simple sugars. That is why foods like potatoes for example‚ may taste sweet to us‚ because they contain starch. The optimum pH for pancreatic

Investigation "We strongly recommend the use of Vanish Stain Removal Tablets in conjunction with a 900 spin wash at 70°C" This was found on a milk carton of a well-known drinks company‚ Nesquick. The major food group constituent of milk is‚ of course‚ milk. For my Science Investigation‚ I am going to test different temperatures

How does temperature affect the rate of reaction for Lipase? As the temperature increases‚ so will the rate of enzyme reaction. However‚ as the temperature exceeds the optimum the rate of reaction will decrease. I predict that at temperatures above 70°C the enzyme lipase will become denatured and at temperatures below 10°C the enzyme will become inactive. Since lipase operates within the human body I’d also predict that its optimum temperature would be around human body temperature which is approximately

Also to determine whether saline and alcohol are inhibitors or activators Hypothesis: PH factor prediction: I predict that as the pH increases so the activity of the enzyme will increase until it reaches optimum pH range (pH 7) because the enzyme is less denatured when it reaches the preferred pH level‚ and after this

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
