DISCUSSION: Bromelian added to Gelatin: Bromelian is an enzyme found in pineapples. When Bromelian is added to gelatin it breaks down the protein and does not allow the gelatin to solidify. There are several factors that can cause an enzyme to slow down or to completely stop reacting. For example‚ temperature and pH can effect enzyme activity. Canned pineapple juice and fresh pineapple juice were used to see how the enzyme would react differently. In fresh pineapple juice the Bromelian have would

Exploring Enzymes - Ground-Up Tissue Activity Abstract Our experiment looked at how increasing the surface area of a substance affects the amount of bubbles created due to the presence of the enzyme catalase. The experiment used two pieces of fish‚ one whole and one ground up‚ which were then covered in hydrogen peroxide. This method allowed us to observe the catalase in ground up fish break down the hydrogen peroxide at a quicker rate than in the piece of fish left intact. This was determined

Jennifer Anatomy and Physiology Enzyme Lab Report Introduction The chemical reaction that is being studied is the hydrolysis of starch. The enzyme that is being studied is amylase. This experiment is looking at the effect of temperature on the rate of the enzymatic hydrolysis of starch. My hypothesis is that the higher the temperature the faster the hydrolysis of the starch would occur. The rationale behind this is that heat

MISEP Chemistry 512 – Jacobs Enzyme Catalyst Lab - Formal Report – August 8‚ 2007 ABSTRACT This investigation examined what would happen to the rate of an enzyme-catalyzed reaction if the concentration of substrate changed. We hypothesized that if the concentration increased‚ then the reaction rate would also increase. To test our question‚ we varied a combination of substrate and buffer‚ totaling 6mL‚ with a constant amount of 2 drops of catalyst. The enzyme catalyst‚ peroxidase‚ increased

The Effects of pH‚ Temperature‚ Enzyme‚ and Substrate Concentrations on Benzoquinone Production BIOL 2051 June 10th 2013 Introduction Enzymes are the ultimate catalysts of living things. Enzymes are made of proteins which are structured and directed by amino acids chains. Enzymes attract and fit substrate molecules to an active site. The active site binds the substrate molecules covalently to enzyme forming an enzyme-substrate complex‚ which catalyzes

of the lab is to see the effects of enzyme concentration on the reaction rate. Part 2: Effect of Substrate Concentration Purpose: The purpose of this part of the lab was to find the effect of substrate concentration on enzyme activity. Part 3: Effect of Temprature Purpose: The purpose of this part of the lab was to determine the effect of temperature on the rate of enzyme activity

Lab Report: Enzyme Lab Your Name: Samantha Butcher Purpose of this Lab What is the goal of this lab? What question is it trying to answer‚ or what problem is it trying to explain? It is going to explain how a liver’s enzymes break down substances that could be harmful.| Hypothesis After reading the lab instructions - but before starting the lab - record your best “educated guess” about what will happen in the experiment. Give your reasons and outline any assumptions that lead

Introduction Enzymes are protein based structures that help speed up chemical reactions. They help these reactions keep up with the everyday metabolic needs and other like functions of organisms. Enzymes are also considered catalysts‚ due to the lowering in activation energy‚ in which they are not consumed or changed at any point during the reaction. These enzymes have three main protein structures that help keep them formed and intact. Stage 1 of these structures is the primary structure‚ which

Sample Lab Report: Factors which Affect the Activity of the Enzyme Catalase Purpose: Must include: background information about concepts involved in the lab‚ statement of purpose of the lab identification of independent and dependent variables. A hypothesis is often not necessary or appropriate. Enzymes are proteins that speed up chemical reactions in cells. They break down molecules called substrates. Each enzyme has only one substrate that it breaks down. Enzymes are produced in

12 Biology (SBI 4U1) Nicole Mikulis Unit: Biochemistry Sept 14 2012 Lab: Effect of temperature and pH on catalase activity BACKGROUND Catalase is an enzyme that detoxifies chemicals that might harm the cell such as hydrogen peroxide (H2O2). The enzyme breaks H2O2 into water and oxygen. The production of the oxygen gas bubbles serves as evidence that the catalase enzyme is working. As catalase is breaking the bonds between H2O2‚ it is releasing energy in the form
