which breaks it into products 3) Products are released ex) BreadFast & Co.’s use of enzymes The company uses many different types of enzymes in the bread making process such as malt and fungal alpha-amylase. Amylase is used to break down starch and produce small dextrins for the yeast to act - which is needed to make bread rise. (Hayes and Laudan‚ 2009) Enzymes also help obtain an even crumb structure‚ dough improvement‚ and result in a higher loaf volume (Mapsenzymes). Bread making companies

in a certain way when a particular substance is present. We put one indicator into the each test tube containing different solutions at a time to see what organic compound is present. The color change in the indicator tells that cornstarch contains starch; honey‚ lettuce‚ and fruit juice contain sugar; corn oil contain lipid; and by comparing with the standard for positive identification of the substance‚ unknown is tested to have protein just as egg white. The result tells what nutrients are in the

The Uses of water in Living Things Topics I have chosen to cover: - Osmosis & Water potential - Condensation & Hydrolysis Reactions - Digestion – the importance of water - Blood and tissue fluid To emphasise the sheer importance of water in living things and to put the content of this essay in to perspective‚ I am firstly going to inform you that the human body is approximately 50-75% water. Without water our body would be unable to successfully perform the numerous complex reactions and

List the substrate and the subunit product of amylase. _starch & maltose respectively__ 2. What effect did boiling and freezing have on enzyme activity? Why? How well did the results compare with your prediction?__Boiling caused amylase to be denatured‚ thus inactivating the enzyme. Freezing has no effect. The function of an enzyme is directly related

LAB 10: NAME: DaeNia La Rodé DATE: 25TH January‚ 2011. FORM CLASS: L6 3 SUBJECT: Biology TITLE: Enzymes AIM: To investigate the effect of substrate concentration on the enzyme amylase INTRODUCTION: Enzymes are perhaps one of the most important proteins of the human body. Enzymes such as amylase‚ an enzyme that breaks down carbohydrates‚ work by means of surface catalysis. In other words‚ the surface of the enzyme enables other molecules to react in a manner they would not be able to without

Amylase. Solutions of starch and amylase were held at selected temperatures by various methods of temperature control. Once the solutions reached and maintained the desired temperature they were combined. Samples at timed intervals were then taken and reacted with a reagent to determine the effect the selected temperatures had on the reaction rate of enzyme and substrate. Results indicated that the enzyme functions efficiently at its optimum temperature (50oC) digesting the starch present and that any

Prompt 2: According to the slide show I have developed an interest in many different foods and would like to try all of them except for the cinnamon. Cinnamon kills people. Cinnamon is too small for the human body to swallow and when trying to do it you choke to death‚ hence the “cinnamon challenge.” Otherwise I have no interest in any of the other foods on that list. There is one food‚ however‚ that I absolutely adore. Back in the old days my family always loved to go out for dinner. No matter what

Concentarion ENZYME LAB Introduction- Enzymes are proteins that speed up the rate of reactions in living things. In this lab‚ we will perform four experiments exploring the way enzymes work. PART A: pH SPECIFICITY Every enzyme has a specific pH at which it works best. In this section‚ you will determine which pH is best for the enzyme‚ catalase. Living tissues produce the enzyme catalase‚ which is able to break down hydrogen peroxide into oxygen gas and water. The reaction is

aim of the experiment is to determine the effects of different pH and the rate of reaction on fungal amylase and starch. Introduction The enzyme amylase is found in the human body‚ it catalyses the hydrolosis of internal glycosidic bonds in polysaccharides‚ the breakdown of starch into sugars. Amylase is present in human saliva‚ where it initiates the chemical process of digestion. Enzymes work best at an optimum pH of 7 which is the bodies normal pH. The pH affects the charge of the amino acid
