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

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 this lab is to observe the catalase found in liver cells by measuring how temperature, pH and enzyme concentrations affect the reaction rates of enzymes. Background Enzymes are considered to be “biological catalysts” meaning they can speed up a chemical reaction in a cell without being used up in the process. Enzymes do this by lowering the amount of energy needed to activate the process. The lower the activation energy, the faster the reaction. Without enzymes, vital life processes
Catalase Enzyme Lab Introduction The human body is an incredible system that is capable of working a multitude of diverse functions. Without the help of the many different protein molecules, the human body would not be able to function properly. One major group of proteins called enzymes are mandatory for essential life. These proteins are constantly at work assembling molecules, metabolizing energy, and fighting off infections. An enzyme is a macromolecule that acts as a catalyst that
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
being an enzyme. An enzyme is an organic catalyst that speeds up the rate of a chemical reaction without being consumed by the reaction. Enzymes are proteins, meaning that they have a unique structure that dictates what their function is. This unique structure also determines what substrate, or specific reactant, the enzyme will catalyze. From there, the substrate and enzyme bind together; which leads to the reactants being created. The enzyme tested during this experiment was the enzyme catalase
Enzyme Action: Testing Catalase Activity 6B Ava Suda Cor Jesu Academy Enzyme Action: Testing Catalase Activity 6B Introduction Hydrogen Peroxide, or H2O2, is harmful to most living organisms but can be converted to oxygen and water before the damage is permanent. This is thanks to enzymes, the biological catalysts that increase the rate of reactions. Enzymes can be studied by measuring the rates of enzyme-catalyzed reactions. This can be done in a number of ways, including measuring
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
Enzymes: Helpful or Harmful? Abstract Enzymes act as catalysts to normalize the speed of the many chemical reactions involved in the Metabolism, of living organisms (2016). Because the enzyme-substrate results from weak bonds that require precise positioning of specific amino acid side chains in the active site, any external factors that affect formation of these bonds can significantly affect enzyme function. These factors include pH, ionic strength, temperature, and the chemical environment. Throughout
