Group Members: Johnny Nguyen‚ Therese Pham‚ Linda Tang Name of Enzyme You are Investigating: Amylase Brief Background: Amylase is a digestive enzyme‚ produced mainly by the salivary glands and the pancreas‚ to break down starch in food into smaller carbohydrate molecules and disaccharides such as maltose. It can be found in humans and some other mammals. Some plants and bacteria may also produce amylase. After being broken down into smaller carbohydrate molecules‚ it can be converted into a monosaccharide

What conditions are necessary for digestion of lipids‚ carbohydrates‚ protein? Certain conditions are required for digestion. I will find that enzyme is required for digestion of lipids‚ carbohydrates‚ protein. There are many conditions that are necessary for digestion of lipids‚ carbohydrates‚ protein such as pH and enzyme and substrate. The test tube that digestion of lipids occurs in was test tube 1‚3‚4‚ test tube 2 there was no digestion because there was no enzyme. Test tube 1 was the fastest

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

These juices are very acidic (pH 1-2). The semi-digested stomach contents are called chyme Esophagus

used directly by living cells to produce energy. Examples of simple sugars are glucose‚ sucrose and lactose. (b) Starch‚ which is a form of carbohydrate‚ is stored in plants. Examples of plants that store starch are tapioca‚ banana and wheat. Extra glucose that is produced by photosynthesis is kept in the form of starch. (c) Glycogen‚ which is a form of carbohydrate is stored in animals. Glycogen is usually stored in the liver and

Experiment 4 – Effect of Temperature on Enzyme Activity Aim To study the effects of temperature on the activity of amylase enzyme on starch solution. Introduction Enzymes are widely known as biological catalyst. Almost all cellular reactions are controlled and guarded by enzymes. Virtually every metabolic reaction which takes place within a living organisms are catalyzed by enzymes. Enzymes are complex three-dimensional globular proteins. Some of the enzymes are built up off proteins and

Understanding the functions of the body systems associated with energy metabolism Energy is used for many of the bodily functions including the ability to ventilate‚ respire‚ move‚ grow and repair. The first law of thermo dynamics states that energy can be transformed from one state to another but cannot be lost. Energy comes in many forms‚ some of these are as follows:- Light Sound Kinetic Heat Chemical In accordance with the First Law an example of how energy can transform is when the sun creates

Biology Form Four Digestion Digestion is the process by which food is broken down from complex insoluble substances into simple soluble substances. There are two types of digestion – chemical digestion and mechanical digestion. Mechanical digestion involves breaking up large pieces of food into smaller pieces. This provides a large surface area for the action of enzymes on food. There is no change to the chemical composition of food during mechanical digestion. Mechanical digestion occurs in
