To investigate the effects of temperature on the activity of lipase enzyme on milk which contain fats or lipids. Introduction: Enzyme is a kind of biological catalyst that made up of protein. It can speed up the metabolic reactions on various kinds of substances. Like lipase can break down lipid into glycerol or fatty acids in milk. Since enzyme is made up of protein which easily affected by varies temperature. This experiment is carried out to find the effects of temperature on the activity of

Activity of Amylase Abstract Does more or less concentration speed up the reaction rate of amylase in starch? In this experiment diluted solutions of amylase were created and then tested using a starch solution‚ I2KI for reaction times. The answer to the question was proved to be that more concentration of amylase speeds up the reaction time. Introduction The enzyme‚ amylase is found in the saliva of most animals and in humans. Amylase hydrolyzes starch‚ a plant’s reservation of carbohydrates

Introduction: Enzymes are biological catalysts that permit cells to carry out the many functions that are required in a living system. Every enzyme has a specific substrate and a specific function. Enzymes alter substrates one of three ways: by adding something to the substrate‚ removing something from the substrate‚ or by changing its conformation‚ otherwise known as its shape. The structure of an enzyme and its ability to function exists because it binds to an active site‚ thus increasing the

According to the results in this lab Jell-O must contain protein due to the fact that the meat tenderizer was able to break down the Jell-O much the same as it would break down the proteins in meat. 5. Did the amount of meat tenderizer give different results? The amount of meat tenderizer did give different results‚ cup â»2 with the least amount of tenderizer did not break down as much as the cup â»3 with the most tenderizer. Conclusion According to this lab it demonstrated that Jell-O does

Enzymes Ashley Njeru Mrs. Booth Tuesday‚ March 19th 2013 SBI 4U INTRODUCTION: The cellular activity of all organisms is controlled through the use of enzymes. An enzyme is a special type of biological molecule‚ usually a protein‚ which speeds up a chemical reaction; most are soluble in water or a dilute salt solution. There are about 4000 different enzymes in a typical living cell. If even one of these enzymes is missing or

Enzyme Reaction to Variable Elizabeth Alvidrez University of Texas at El Paso Abstract: An enzyme is a protein that serves as a biological catalyst (Denniston‚ 2007). Metabolic reactions happen with in cells. Enzymes are proteins that are used to speed up these reactions without being consumed by them (Mader‚ 2010). Catalase is a catalyst that digests potent hydrogen peroxide and converts it into H2O and O (Campbell Reese‚ 2008). The environment plays an important role

reaction. Life would not exist without the presence of enzymes (Phillips‚ 2017). Through chemical reactions‚ this energy is created and is controlled by a catalyst‚ enzymes. Enzymes are known as proteins that are produced in living cells that speed up the metabolic processes of an organism. These catalysts speed up these reactions by decreasing the activation energy‚ how much energy is needed for a chemical reaction to happen (WBC‚ 2015). An enzyme-substrate complex forms when a substrate attaches to

The purpose of this lab was to determine if a there is a change in mass when a gas is produced and determine if gas has mass. To conduct this experiment‚ the group must be careful not to let the Alka-Seltzer tablet get wet before the bottle is closed by wiping the lip of the bottle and the cap so it remains dry‚ or risk gas escaping into the air and not being captured by the bottle. Also‚ the group must be sure to close the bottle tightly with the cap‚ because gas may escape this way as well. During

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

Simple Experiments on the Enzyme Catalase Aim: The aim of this practical is to use three different techniques to investigate the effect of different concentrations of the enzyme catalase on the rate of breakdown of hydrogen peroxide. Background information Catalase is an enzyme which is found in all living organisms. This enzyme catalases the decomposition of hydrogen peroxide into water and oxygen. Cells continually produce a poisonous by-product of metabolising‚ called hydrogen peroxide. This
