Ah Seung Chong Molecular Biology CTW: Enzyme Kinetic Dr. Cruz 07/22/2010 Enzyme kinetics Introduction Enzymes are biological catalysts or assistants‚ without enzyme many of important processes of life could not happen. Most of enzymes are proteins that help speed up chemical reactions by lowering amount of activation energy needed for the reaction1. Enzymes are usually highly selective‚ only bind to specific substrate and convert it to product at a particular rate1. The rate of the reaction

ENZYMES LABORATORY REPORT Introduction The utilization of any complex molecule for energy by an organism is dependent on a process called hydrolysis. Hydrolysis breaks complex molecules into simpler molecules using water. Similarly‚ the process that is the reverse of this is called dehydration synthesis‚ which removes water from simpler molecules. However‚ because hydrolysis occurs very slowly‚ living organisms use biochemical’s called enzymes to speed up the reaction. In this lab exercise

Lab Topic: Movement of Materials Across the Cell Membrane—Potato Tuber Cells Introduction: Osmosis is a form of diffusion in which water diffuses through a selectively permeable membrane from a region of high concentration to a region of lower concentration. This form of diffusion takes place when the molecules in high concentration are too large to move through the membrane. Three factors that determine cell membrane permeability are shape‚ size‚ and polarity. For this experiment‚ it must

Effect of Temperature ( C ͦ) on Enzyme Catalase Activity in potato Aim: To investigate the Effect of temperature (10‚ 37‚ 60) Celsius (C ͦ) on enzyme catalase activity in potato using 2% of hydrogen peroxide (H202) as the substrate measuring the height (cm) of oxygen gas (bubbles) and calculating the volume of oxygen bubbles produced (cm3) Introduction: Enzymes are biological catalysts that speed up metabolic reactions without being affected. They lower the activation energy needed to start

How to Write a Lab Report Lab reports are formal papers that describe and analyze lab experiments. They follow a very specific format. If you study this paper carefully and follow its directions‚ you will find that these papers are not at all difficult and can have a positive impact on your Biology grade. Paper formatting: The paper should be typed and double spaced. Use a standard 12 point font (do not use cute fonts or colored paper!). Except for the title and abstract – each section

Varibles that affect Enzyme Catalysis Reaction Rates Introduction Molecules are constantly moving in our bodies and in nature. When molecules move fast enough they collide into one another‚ allowing chemical reactions to occur. Factors such as temperature and concentrations can either help increase or decrease these reactions. (Jubenville.) Enzymes are known as catalyst because they are able to speed up reaction rates without being destroyed or altered. They are able to encourage chemical reactions

Environment Can Effect Enzymes Introduction: In a chemical reaction there sometimes can be a catalyst present known as an enzyme. An enzyme is a protein that speeds up a chemical reaction by lowering the amount of activation energy required to start the reaction. By lowering the activation energy‚ more of the substrate is able to participate in the reaction‚ speeding it up. Enzymes are substrate specific. The substrate is what the enzyme bonds to. That is to say that enzyme A will only react with

of this lab was to compare the action of a catalyst (enzyme) under different environmental conditions. This was determined by performing a variety of different experiments. The first experiment was performed by adding hydrogen peroxide to sand. Due to the fact that the sand was not soluble in the hydrogen peroxide‚ no reaction thus no catalyst were present. Manganese dioxide was also added to the hydrogen peroxide creating a moderately fast reaction thus leading to believe that an enzyme was present

Lab Report An enzyme is a protein that speeds up the rates of chemical reactions. They recognize‚ bind‚ and change specific reactants. They do not change so they can catalyze the same reaction again and again. Activation energy is the amount of energy needed in order to begin a chemical reaction. A Catalyst is a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change. Catalysts are substances or a substance that configures another substance
