Enzyme Catalysis Lab Problem: Before the lab‚ one should understand: • The general functions and activities of enzymes; • The relationship between the structure and function of enzymes • The concept of initial reaction rates of enzymes; • How the concept of free energy relates to enzyme activity; • That change in temperature‚ pH‚ enzyme concentration‚ and substrate concentration can affect the initial reaction rates of enzyme-catalyzed reactions; and • Catalyst‚ catalysis‚ and catalase

Potato Enzyme Lab Enzymes are protein catalysts that speed up chemical reaction in living organisms. The purpose of this lab was to; observe the breakdown of hydrogen peroxide toxin by potato’s enzyme catalase‚ determine factors that influence how quickly the reaction takes place‚ and determine factors that influence how well enzymes function. The first test‚ we were supposed to see what would happen when we add sand in hydrogen peroxide. We filled a test tube with 5mL hydrogen peroxide and we added

PART B YOU WILL NOW DESIGN AN EXPERIMENT TO STUDY THE EFFECT OF A FACTOR AFFECTING VITAMIN C IN FRUIT JUICES WHAT IS THE EFFECT OF TEMPERATURE ON VITAMIN C IN FRUIT JUICES? The purpose of this experiment is to determine if the difference in temperature will damage vitamin C in any type of fruit juices. Five different temperatures of fruit juices will be used(5‚ 22‚ 50‚ 70‚ 90) degree Celsius to see how temperature affects the loss of vitamin C in fruit juices. The amount of vitamin C in the fruit

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

that way if you believe in the power of change. Hydrogen fuel is that change for the automobiles of the future. Hydrogen has been used for decades‚ but mostly for commercial use. Each year‚ we get closer to removing the oil company’s choke hold on our wallets. It’s time to drive with a lighter purse and a cleaner environment and it’s time for hydrogen fuel. The two largest points of debate with hydrogen fuel are cost and production Hydrogen fuel is a cheaper alternative to our current source

The Effects of Substrate Concentration‚ Reaction Time and Enzyme Concentration on Enzyme Reactions Corey von Ellm-St. Croix Rachael Kwan ID#: 20427841 Matthew Hrycyshyn & Saeideh Mayanloo Biol 130L‚ Section 017 Wednesday‚ 9:30am-12:20pm‚ 151 November 09‚ 2011 A living system controls its activity through enzymes. Enzymes are made from hundreds or even thousands of amino acids connected in a very unique and specific order. Almost all enzymes are proteins‚ except for ribozymes. The chain

Enzymes are biological catalysts‚ large protein proteins that have a very specific three-dimensional shape which makes them highly specific and only work on one or a few similar chemical reactions. Enzymes themselves are not consumed in the reaction‚ but they help attract substrates into correct position to undergo chemical reaction. Enzymes greatly speed up the rate of biological reactions by lowering the energy of activation. To get a sense of the speed and efficiency of enzymes‚ substrates can

more efficient sources of power. At the forefront of research for these power sources are hydrogen fuel cells. This power source takes in the most abundant element in the universe‚ Hydrogen‚ and yields immense power without combustion or pollution. The three aspects of this scientific breakthrough are the fuel cells‚ hydrogen production‚ and hydrogen storage. Fuel cells are the devices with which Hydrogen is made into electricity. These use a technology much similar to that of something we are

Running head: LAB 5: INVESTIGATING AN ENZYME-CATALYZED REACTION Lab 5: Investigating an Enzyme-Catalyzed Reaction September 24‚ 2014 Principles of Biology 120.601 Mrs. Annemarie Duncan Abstract: (Burmania) This experiment was performed in order to examine ways in which a potato catalase enzyme reacts to various assays with differing variables. To do so a baseline assay (undiluted extract and room temperature H2O2) was used within the experiment with only one other variable changed in

Abstract: This project looks at how the temperature of an experiment can affect its reaction time. The purpose of this experiment is to determine if dissolving reactions are affected by waters temperature. I believe that if the H2O temperature increases‚ then the Alka-Seltzer tablet will dissolve faster because the hot water molecules will move faster colliding with the tablet particles. Water will be the independent variable due to the fact is will always stay in its same form throughout the
