Hence‚ this experiment is focused on diffusion and required to create a own model cell by pouring distilled H2O‚ starch‚ iodine and glucose in tied dialysis tubing to test for substance which diffuse through the membrane and which one could not due to its size. Materials and Methods Materials: * Distilled H2O * Starch solution * Iodine solution * Glucose solution * Test tube (3-4/group) * Test tube rack * Marking tape * Benedict’s test solution * Hot water bath

of making wine.The Reason why yeast was chosen to was to see how yeast can metabolize different sugars and how much Co2 they release when when metabolizing.To test the yeast at the lab we used 4 different types of carbohydrates which are known as Glucose‚Lactose‚Sucrose‚and Starch.The main thing that make some of these carbohydrates different from each other is if it’s a Monosaccharide‚ Disaccharide‚or Polysaccharide. Monosaccharide are basic sugars

CARBOHYDRATES: REDUCING SUGARS The reducing sugars include all monosaccharides‚ such as glucose and fructose‚ and some disaccharides‚ such as maltose. Test Benedict’s test Add 2cm3 of a solution of the reducing sugar to a test-tube. Add an equal volume of Benedict’s solution. Shake and place into boiling water. Boil for 2-5 minutes;

Tim Readmond AP Biology Lab Report I. Title a. Modeling Diffusion and Osmosis II. Introduction a. If one places a 1.0 M solution of glucose inside a bag and then places that bag into a beaker containing a 1.0 M solution of sucrose‚ the percent of mass lost in the bag is 10.5%. The solution in the bag is hypertonic while the solution in the beaker is hypertonic‚ which is why water moves from the bag to the beaker and the bag loses mass. b. The purpose of this experiment is to see whether

Title : Investigation of Action of Saliva and 3M HCl in Two Carbohydrates Solutions. Objective : To investigate the action of saliva and 3M hydrochloric acid in two carbohydrate solution. Result : Table 1 : The presence of starch and reducing sugar in the solution Observation Conclusion Solution A Benedict’s test : The transparent blue solution turns into opaque brick-red precipitate Iodine’s test : The clear colourless solution turns into transparent yellowish-brown

Amylase breaking down the starch suspension into maltose and maltose into glucose when HCL was added into solution B .This is because solution B was hydrolyzed and the H+ ions present break down the bond in between molecules of the solution B.

rapidly depleted. One molecule of CP produces one ATP. 6. Glucose is a major source of energy for synthesizing ATP. List the two sources of glucose: 1. Glucose enters the muscle cell directly from the blood. 2. Glucose is produced by hydrolysis of glycogen stored in the muscle cell. 7. Glycolysis is the process that breaks down glucose. Name two products of the breakdown of glucose: 1. Two ATP molecules 2. Pyruvic acid If oxygen is not
