most important parts. Along with this the chemical process also begins where your salivary glands start to produce saliva. Technically the salivary glands tend to get activated upon smelling the food‚ therefore your mouth starts to water. Saliva‚ which is a mixture of enzymes and water created by the cells in the epithelial tissue lining the mouth‚ keeps the mouth and other parts moist throughout the process. The salivary glands also help break down carbohydrates and lubricate the passage of food down

through which food passes: mouth‚ pharynx‚ esophagus‚ stomach‚ small intestine. Each portion is specialized for one or more aspect of the three major functions of the digestive system the secretion‚ digestion‚ and absorption. Accessory organs such as salivary glands‚ liver‚ gallbladder and pancreas have duct that lead into the digestive tract and thus support digestive function. Digestion is defined as the mechanical and chemical breaking down of food into smaller components‚ to a form that can be absorbed

Effect of different temperatures on the rate of an enzyme controlled reaction I will place starch and amylase into five water baths which are at different temperatures‚ and record the time it takes to break down the starch in the solution. Independent variables The independent variable is what I am going to change in my experiment. In this case it is the temperature of the water in the five water baths- 10‚ 25‚ 40‚ 55‚ 70 degrees Celsius Dependant variable This is what will stay the

with starch. The enzyme that we are going to use is called amylase. We are going to test this enzyme with starch. By mixing amylase and starch solutions together under different temperature conditions‚ we can record the rate of reaction by taking a sample out and test it with iodine solution to see if there is any remaining starch present. We have to use the enzyme amylase because enzymes will only work on a specific substrate i.e. amylase will work on starch because of its special shape of active

still the most important detergent enzymes. Lipases decompose fats into more water-soluble compounds. Amylases are used in detergents to remove starch based stains. 2. Starch hydrolysis and fructose production The use of starch degrading enzymes was the first large scale application of microbial enzymes in food industry. Mainly two enzymes carry out conversion of starch to glucose: alpha-amylase and fungal enzymes. Fructose produced from sucrose as a starting material. Sucrose is split by invertase

active site of the enzyme is complementary to the shape and polarity of the substrate. Typically‚ only one kind of substrate will “fit” into the active site. In this experiment‚ we will work with the enzyme amylase. This enzyme is responsible for hydrolyzing starch. In the presence of amylase‚ a sample of starch will be hydrolyzed to shorter polysaccharides‚ dextrins‚ maltose‚ and glucose. The extent of the hydrolysis depends on how long it is allowed to react – if the starch is hydrolyzed completely

Jennifer Anatomy and Physiology Enzyme Lab Report Introduction The chemical reaction that is being studied is the hydrolysis of starch. The enzyme that is being studied is amylase. This experiment is looking at the effect of temperature on the rate of the enzymatic hydrolysis of starch. My hypothesis is that the higher the temperature the faster the hydrolysis of the starch would occur. The rationale behind this is that heat

Unit 5 Outcome 2 – Energy Metabolism Booklet The Respiratory System The respiratory system consists of the nose‚ mouth‚ pharynx‚ larynx‚ trachea‚ bronchi and lungs. These provide a passageway to allow air in and out of the body. Every cell in the body requires oxygen to survive. The primary function of the respiratory system is the exchange of gases. The respiratory system allows oxygen and carbon dioxide exchange‚ this is necessary to sustain life. During the process of breathing air is inhaled

Thus‚ if further studies are conducted on different enzymes‚ the more information is covered about certain organisms. In the experiment‚ each enzyme source was put to the test by being placed into different test tubes and baths with altered temperatures. In order to see how long the Amylase was hydrolyzing starch in different
