Enzymes Lab Report Introduction Organisms cannot depend solely on spontaneous reactions for the production of materials because they occur slowly and are not responsive to the organism's needs (Martineau, Dean, et al, Laboratory Manual, 43). In order to speed up the reaction process, cells use enzymes as biological catalysts. Enzymes are able to speed up the reaction through lowering activation energy. Additionally, enzymes facilitate reactions without being consumed (manual,43). Each enzyme acts
Cheyenne Hylton Name of Lab: Properties of Enzymes Date: November 2015 Name of Instructor: Mr. Jeffrey Ellis Subject Section: Biology I/Lab 1500 (DAC) Abstract: In this lab or experiment, the aim was to determine the following factors of enzymes: (1) the effects of enzymes concentration the catalytic rate or the rate of the reaction, (2) the effects of pH on a particular enzyme, an enzyme known and referred throughout this experiment as ALP (alkaline phosphate enzyme) and lastly (3) the
The purpose of the enzyme lab conducted was to observe the chemical composition of cells. In order to do so we tested for the presence of organic molecules. Molecules are what forms when atoms bond together. Organic molecules of cells include proteins, carbohydrates, and lipids, which are composed of smaller molecules known as monomers and polymers. Polymers are joined monomers. A chemical reaction links monomers together occurs and releases a water molecule, this is called dehydration synthesis

Amenah Ali Ms.Corbett IB Biology HL I Period 5 December 13, 2017 Enzyme Design Lab Research Question: At what temperature does an enzyme react at its optimum rate? Background Information: Hydrogen Peroxide is a by product of many biological and chemical functions of organism. Although it is toxic, it still remains in our cells. To counter the hydrogen peroxide we produce something called a catalase. This means that with a catalase, it can cause the chemical reaction to speed up the reaction of
In this lab the effect of the enzyme concentration has on the speed of the reaction will be observed. The amount of oxygen gas produced will be measured to determine the reaction rate. If the enzyme concentration increases then the reaction rate will also increase. The measure of how fats oxygen is produced will be how long it takes for the filter paper disk soaked in different concentrations of catalase to rise to the top. If catalase is exposed to boiling temperature then it will denature. Catalyst
Gail Francis Enzyme Lab Introduction Enzymes are organic catalysts that speed up metabolic reactions (Denniston, 2007). In short, enzyme functions by binding one or more of the reactants in a reaction. Specific enzymes only lower the activation energy for specific reactions and enzymes are shape-specific. The reactants that bind to the enzyme are known as substrates of the enzyme. The exact location on the enzyme where substrate binding takes place is called the active site of the enzyme. When substrates
Enzyme Lab Majesty Collins September 26, 2017 Finding the Greatest Amount of Product with a Spectrophotometer Introduction For the enzyme experiment, I hypothesized that test tube number one would have the greatest amount of product. My lab partners and I believed that number one would have the most significant amount of product because it had the highest mL amount of the potato extract. The potato extract is the enzyme of the investigation being used which is catecholase (Picture
Experimenting with Enzymes Exploration Lab Ali Al-Husseini IB Biology 5th Period Exploration- How does increasing the substrate concentration of Hydrogen Peroxide from 0 to 15% at 3% intervals affect the enzyme catalase in yeast? In this lab, the independent variable would be the hydrogen peroxide concentration. The concentrations used in this lab will be 0%, 3%, 6%, 9%, 12%, and 15% concentration. The dependent variable is the rate or reaction which is the actual time
Lab: Enzymes – Protein Catalysts Abstract: Enzymes are catalysts therefore we can state that they work to start a reaction or speed it up. The chemical transformed due to the enzyme (catalase) is known as the substrate. In this lab the chemical used was hydrogen peroxide because it can be broken down by catalase. The substrate in this lab would be hydrogen peroxide and the enzymes used will be catalase which is found in both potatoes and liver. This substrate will fill the active sites on the
