    Mechanical digestions starts from the intake of food into the mouth and when the food is chewed and while the food is broken down until it becomes small to be swallowed. Then the food goes down as a food bolus into the esophagus after the food is broken down. The food bolus passes through the alimentary canal through peristaltic movements. Peristaltic movements is a systematic series of muscle contractions and relaxation which involves the passage of food bolus through the esophagus‚ stomach‚ small

    things we eat turn into things such as carbohydrates‚ fats‚ and proteins. Carbohydrates are‚ any of a large group of organic compounds occurring in foods and living tissues and including sugars‚ starch‚ and cellulose. Protein‚ such as meat‚ eggs‚ and beans‚ consist of large molecules of protein that must be digested by enzymes before they can be used to build and repair body tissues. An enzyme in the juice of the stomach starts the digestion. Further digestion

    mouth is a part of the body where people use mechanical digestion and use their teeth to break down their food. With the help of saliva produced by the salivary glands‚ which produce enzymes‚ food is able to be broken down further. This is also the place where ingestion takes place” “What are enzymes” “Enzymes are very efficient catalysts for biochemical reactions. In the mouth there’s an enzyme that will help your food undergo chemical digestion” “What is it” “It is amylase. Which help digest starch

    Practical 12: Digestion in Humans Aim: To distinguish between 5 liquids to come to a conclusion from which region of the alimentary canal it was extracted from. Hypothesis In this practical‚ we have been given 5 unknown solutions hence it is not possible for us without any logical analysis to come up with a conclusion regarding the positioning along the alimentary canal. We cannot come up with a proper answer or predict results without running through the tests. I though can base my

    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 for digestion because the

    #) Identifying Carbohydrates (First inital and last name of lab partner) Purpose The purpose of this lab is to learn how to identify different forms of carbohydrates by conducting the Benedict and Iodine test. Theory The theory for this concept is that if in the benedicts test the carbohydrate reacts‚ it is a monosaccharide. If it reacts in the Iodine test it is a polysaccharide. If no reaction occurs in either test the carbohydrate is a disaccharide. Data Type of carbohydrate | Benedicts Test

    Pre-lab 1: Identifying Carbohydrates Abstract The point of this lab is to determine if a substance contains carbohydrates such as a reducing sugar and/or polysaccharides. This will be done by using Benedict’s reagent and Iodine stain tests. Benedict’s reagent will react to reducing substances in the solution by oxidizing it and changing the structure of the reducing sugar to form a colored precipitate. The color of this precipitate can be used to determine the concentration of reducing sugars in

    Analysis: Lab 1 Identifying Carbohydrates There were many ranges of color changes in the Benedicts test and Iodine stain. For the Benedicts test‚ this oxidation/reduction response changes the arrangement of the reducing sugar creating a colored precipitate. The change in color is correlated to the first concentration of the reducing sugar. For the iodine test‚ the three dimensional structure of various polysaccharides permits them to react with the iodine stain to produce a certain color. As far

    D_____ J_____ CARBOHYDRATES LAB May 22‚ 2013 Pre-lab Questions 1. The water in test tube No. 1 is a negative control. No reaction is expected to occur because water is not a carbohydrate. Reaction by a negative control is evidence of contamination. 2. The color changes expected for positive test results are Benedict’s test: orange to brick red Tollen’s test: metallic silver Starch iodine test: blue-black 3. Identify each of the samples in Part 1 as monosaccharide
