Lab Report DIFFUSION AND THE EFFECT OF AMYLASE. Aim: We will interpret and explain the activity of an enzyme added to a solution. We will analyze reactions in different pH ranges. The starch solution will appear blue when mixed with iodine. But after mixing the enzyme amylase to the starch‚ the starches are broken down into simple sugars. Now‚ when the iodine is added‚ no color change exist. Instruments and materials used: 1.) Dialysis bags x2 2.)

are amylases? Amylases are enzymes that break down starch or glycogen. Amylases are produced by a variety of living organisms‚ ranging from bacteria to plants and humans. Bacteria and fungi secrete amylases to the outside of their cells to carry out extracellular digestion. When they have broken down the insoluble starch‚ the soluble end products such as (glucose or maltose) are absorbed into their cells. Amylases are classified based on how they break down starch molecules i. α-amylase (alpha-amylase)

Digestion begins in the mouth when one eats food. It begins the moment one takes a sandwich bite. The teeth are used to break the sandwich that contains lettuce and pickles into smaller particles or boluses so that the enzymes can digest the food much easier. Lettuce contains carbohydrates‚ proteins and fat. The tongue helps turn food in the mouth and mix with the saliva in the mouth which contains salivary amylase enzyme. It then passes through the esophagus to the stomach which is a mixer and grinder

Lipid Digestion The process of mastication is our only conscious act in the digestion of the foods we consume. After that‚ it’s out of sight‚ out of mind; but should it be? What does it take to transform that last swallow into the energy our body needs to sustain itself? In the case of lipid digestion‚ the real magic occurs throughout the gastrointestinal tract with a synergistic collaboration from the accessory organs: the liver‚ gallbladder and pancreas. Understanding the whole process of digestion

Effects of pH on fungal amylase activity BI 211 November 25‚ 2011 Introduction In recent years‚ the uses of microorganisms have become a huge importance to industry and sparked a large interest into the exploration of enzyme activity in microorganisms. Amylase is one of the most widely used enzyme required for the preparation of fermented foods. Apart from food and starch industries‚ in which demand for them is increasing continuously‚ amylase is also used in various

Checkpoint: Human Digestion SCI/241 June 4‚ 2013 The path that food follows through the digestive system is very interesting. First you put the food to your mouth‚ take a bite‚ and chew. The salivary glands begin the digestive process at the sight and smell of food. After food enters the mouth and is moistened by saliva‚ it transforms into a bolus. Once the bolus leaves the mouth‚ it moves into the pharynx‚ where it can be swallowed. The bolus then moves from the pharynx to the stomach

! Affect of pH on Porcine Pancreatic Alpha-Amylase Activity Introduction Proteins function in a variety of different ways‚ and one of their fundamental tasks is to act as enzymes. Enzymes are extremely important in controlling reaction speed (by initiating and regulating biological activity)‚ cell communication‚ and growth. One particularly significant enzyme is amylase‚ which catalyzes the hydrolysis of alpha glycosidic linkages of amylose‚ starch components‚ and other oligosaccharides (Qian

Starch/Amylase Experiment Report Objective: The purpose of the starch/amylase experiment was to simulate and observe the process of enzyme digestion. Materials: * 1 small beaker * 2 large beakers * 2 cut pieces of soaked dialysis tubing * 2 dialysis tubing clamps or pieces of twine * 2 clean plastic pipettes * 1 bottle of Lugol’s solution * 2 glucose test strips Procedure: Begin the experiment by placing 4 full pipettes worth of cooked starch in a beaker. Then‚ use
