The enzyme that involved in the reaction is salivary amylase. The action of amylase on starch is with the mixture of IKI (iodine and potassium iodide test).Starch solution will have a blue-black colour in the mixture but no changes in colour for maltose solution. When hydrochloric acid (HCl) is added to the starch solution‚ the color will

accurate and reliable. For everything else‚ I followed my original plan. To ensure the results were accurate‚ I made sure I accurately measured out the amylase and starch solutions for each experiment. This is because‚ if I had the wrong amounts‚ I would not get a valid conclusion‚ as I will not know whether my results are affected by the concentration of starch‚ or whether the results I got were due to the amounts of solution used. This would make both my results and conclusion invalid and unreliable

Austin Peay State University Department of Chemistry CHEM 1021 BREAKING DOWN STARCH USING SALIVARY AMYLASE Caution: You will be using a Bunsen burner and glassware to create your own constant water bath. Appropriate caution should be exercised when dealing with the Bunsen burner‚ hot water‚ and glassware. Purpose: Many plants store their energy in the form of starch‚ a polysaccharide made from repeating units of the monosaccharide glucose. Our bodie

The Effect Of Substrate Concentration On The Activity Of The Enzyme Catalase A Level Biology Project Aims This is an experiment to examine how the concentration of the substrate hydrogen peroxide affects the rate of reaction of the enzyme catalase. Background Information Enzymes such as Catalase are protein molecules which are found in living cells. They are used to speed up specific reactions in the cells. They are all very specific as each enzyme just performs one particular reaction. Catalase

Effects of Temperature‚ pH‚ Enzyme Concentration‚ and Substrate Concentration on Enzymatic Activity INTRODUCTION Enzymes‚ proteins that act as catalysts‚ are the most important type of protein[1]. Catalysts speed up chemical reactions and can go without being used up or changed [3] Without enzymes‚ the biochemical reactions that take place will react too slowly to keep up with the metabolic needs and the life functions of organisms. Catecholase is a reaction between oxygen and catechol

detoxifying hydrogen peroxide and preventing the formation of carbon dioxide bubbles in the blood. This laboratory exercise involves the use of an enzyme that will react with hydrogen peroxide. The enzyme is catalase and hydrogen peroxide (H2O2) is the substrate. The reaction is as follows: catalase 2H2O2 2H2O + O2 Ingested hydrogen peroxide is a poison‚ while external use of this substance is not. However‚ the generation of oxygen gas requires careful handling

The effect of enzyme concentration‚ substrate concentration‚ pH‚ and temperature on the enzyme catalase. Introduction: Enzymes are biological catalysts; proteins and RNA. They are required for most biological reactions and they are highly specific. Each enzyme has an active site. The active site is the spot on the enzyme where a substrate fits in. Substrates binds with enzymes through the active site. Enzymes‚ being highly specific‚ only fit with one certain substrate. Enzymes and substrates

Title: “The Effect of Substrate Concentration‚ Enzyme Concentration‚ pH and Temperature on Enzyme Activity” Abstract: In the following experiments we will measure precise amounts of potato extract as well as Phenylthiourea‚ combined with or without deionized water and in some instances change the temperature and observe and record the reaction. We will also investigate the different levels of prepared pH on varying samples of the potato extract and the Phenylthiourea and record the results.
