Enzymes are large globular proteins which act as biological catalysts. They increase the rate of reaction without being used up by themselves. They are found in and out of cells and lower the activation energy of a reaction. Amylase is the enzyme which catalyses starch hydrolysis. Alpha amylase and beta amylase are two types of amylase enzymes. The amylase which is the most commonly found in the human body is the alpha amylase. Beta amylase is mainly found in bacteria‚ fungi and plants. Amylase breakdown

PH level of Amylase Background info: What is Amylase? Amylase is an enzyme that helps digest carbohydrates. It is produced in the pancreas and the salivary glands. (Dugdale & Longstreth‚ 2011) Factors Affecting Amylase: Things that affect the efficiency of Amylase are temperature and pH levels. (Wikimedia Foundation‚ Inc‚ 2013) Function in the body: The function of Amylase in the human body is to break down plant-based starch sources. Therefore‚ providing the human body with more

conditions and enzyme function. *There are many environmental factors these may include temperature because if its too cold the enzyme would still work but it would work slowly and if its too hot the enzyme will become denatured. As the temperature increases‚ the kinetic energy of the molecules increase so they move around more meaning that there are more collisions between the enzymes and substrates molecules and therefore more reactions. pH is a factor because the different types of enzymes work best

designed to test the reaction of the enzyme amylase at various temperatures. There were two different kinds of amylase being tested‚ one was fungal amylase also known as aspergillus oryzae and human amylase. The changes in temperature effect the rate at which an enzyme and a substrate collide. When the temperature is too high the active site changes shape or denatures‚ once this occurs it stops substrates from attaching themselves to their corresponding enzyme. When the temperature is too low it decreases

1 The Limits of Amylase 2-1-14 Abstract This report explains the purpose of this experiment in a way that conveys information to the reader about Amylase’s ability to withstand acidic or basic pH. To do this‚ two test tubes were both filled with 5mL of a 5% amylase solution. The first one was filled with an acid‚ while the other was filled with a base. After dropping liquid Iodine and Benedict’s solution into each one‚ the tube with a basic pH tested positive for glucose. The acidic solution

Abstract This lab was focused on determining the optimal temperature of the enzyme amylase responsible for catabolizing starch polymers and to see how different temperatures affected the rate as well as how effectively the enzyme worked. To proceed with the experiment the group set up four different test tubes for each‚ bacteria and fungal amylase‚ and labeled them accordingly with different temperatures as well as different solutions . Then the spot plates were placed on the time and temperature

Identification of unknown a-Amylase through testing different temperatures and pH values to detect the absorbance of maltose. Introduction: Enzymes are biological catalysts‚ mainly proteins for this experiment‚ generated by an organism to speed up chemical reactions. They have active sites on which the substrate is attached‚ and then broken up or joined. For this experiment we are going to work with the enzyme a-amylase. Amylase is an enzyme that breaks starch down into sugar. Amylase is present in human

Effect of different temperatures on amylase activity. Literature review This study is an attempt to follow the activity of amylase because it has a major role in the life of living organisms and is found abundantly in them. Amylase is a catalytic enzyme which hydrolyzes starch into maltose and dextrin at a certain temperature (Biology.kenyon.edu‚ 2015). In plants such as fruits and vegetables carbohydrates are referred to starch which is polysaccharide and is converted into disaccharide and eventually

The Effects of Temperature on the Action of Diastase on a Starch Suspension Hypothesis: The practical being carried out is to observe the effects of temperature on starch break down using a synthesized version of salivary amylase‚ this being Diastase. The starch will be placed into the Diastase and water and then placed in baths of water of different l. temperatures. The test tube containing water will have little or no reaction at all. However‚ the test tube containing the Diastase

relationship between temperature and the enzyme activity of amylase. This was achieved by attaining amylase enzyme‚ starch solution and potassium iodide (determines if enzymes hydrolyses the starch solution)‚ water bath and a hot plate. The temperatures used for this experiment were room temperature‚ 37oC‚ 60oC‚ 80oC‚ and 90oC. The hypothesis developed was that as the temperature increased‚ so will enzyme activity. Therefore‚ the ability of the enzyme to break down the starch solution will occur
