name University name City, State Date Introduction The purpose of the experiment was to test the free sulphydryl groups that may be important for the enzyme activities as well as the roles that the disulphide bonds plays n the stabilizing of the structure that is 3 dimensional of the enzymes and proteins. The latter purpose is vital in the study of proteins. The results for tube 2 showed that N= 6.588 and that tube 3 showed that N= 0.153 sulphide groups in the samples

galactosidase is a hydrolase enzyme and it is also known as beta gal. It causes the hydrolysis of the polysaccharides that is it uses the water to break down the sugar molecules in to simpler and smaller compounds such as simple sugars. It acts on different substrates to break it down as it is a catabolic enzyme. The important substrates are lactose, lactoslyceramides, gangliosides and many other glycoproteins but lactose is an important substrate and sometimes this enzyme has been recognized by its

Temperature can affect a lot of different factors hence its effect on enzyme activity is very complex. It affects the speeds of molecules, the activation energy of the catalytic reaction and the thermal stability of the enzyme and substrate. At low temperatures (say at around 0 centigrade) the rate of enzyme reaction is very slow. The molecules have low kinetic energy and collisions between them are less frequent and even if they do collide the molecules do not posses the minimum activation energy

Enzymes Ally Wormaan 11/07/2013 Section 018 Introduction: Our body has many cells, cells which operate like a chemical factory. Chemicals are broken down for things like energy, and new chemicals are then synthesized. The food we eat only supplies us with some of the compounds that are needed for our body to operate. Most that are needed are synthesized within the cell by hundreds of different types of reactions that are all part of metabolism. All of these reactions wouldn’t be able to take

Title: What is the effect of temperature on Enzyme activity? Purpose: Enzymes are proteins that speed up chemical reactions in cells. They break down molecules called substrates. Each enzymes have only one substrate that breaks down. Enzymes are produced in the cells of the body and affect the rate of almost all the chemical reactions which take place in living organisms. The rate of enzymes activity is influenced by temperature, pH, and substrate concentration. The purpose of this

Cindy Rodriguez Professor. Mascarano Biology Lab Fall 2014 Determining the properties of an enzyme Abstract: To determine the properties of an enzyme, a peroxidase, turnip extract is used in this experiment Enzymes are large proteins that are responsible for the speed at which chemical reactions they are involved in taking place. Enzymes speed up chemical reactions by lowering the activation energy of a reaction, the amount of energy necessary to trigger a

Effects of Temperature, pH, Enzyme Concentration , and Substrate Concentration on Catecholase Introduction Enzymes are biological proteins that speed up the reaction rate of a chemical reaction. They work in the human body by lowering activation energy making certain that reactions will initiate. For every action, there is an equal and opposite reaction. In this case, factors that influence the activity of an enzyme are called modulators. If modulators activate enzymes the reaction rate catalyzed

Eugene’s Story A. What are electrolytes and why is the doctor concerned about them with respect to Eugene’s heart and brain? An electrolyte is an ionic compound that breaks apart into positive and negative ions in solution. In solution, electrolytes can conduct an electrical current. The doctor could be concerned about Eugene’s electrolytes because they are critical for controlling water movement throughout the body, maintaining acid-base balance, and conducting nerve and muscle impulses.
