Experiment 9. The action of saliva on starch Study the flow chart on p. 9.02 for a few minutes to gain an idea of the outline of the experiment. (a) Prepare a water bath by using a Bunsen burner to heat some water in a beaker on a tripod and gauze till it boils; then turn the flame down to keep the water just boiling. While waiting for the water to boil‚ carry on from (b). (b) Label eight test-tubes 1 - 8 and in tube 1 collect saliva as follows: (i) Thoroughly rinse the mouth with

Introduction: In this lab i used glucose and starch to show if the cell membrane is permeable‚ impermeable‚ or selectively permeable to these substances. Dialysis tubing is a plastic like substance that has small pores in it. These pores allow certain chemicals to flow into and out of the cells. The size of the molecule determines what goes through the tubing. On of the materials that we will be using is glucose. glucose is a simple sugar that easily dissolves in water. To test for the presence of

affected by temperature and pH value. In this experiment‚ enzyme was placed in carbohydrate solution at different temperature to identify unknown carbohydrate solution. The enzyme that involved in the reaction is salivary amylase. The action of amylase on starch is with the mixture of IKI (iodine and potassium iodide test).Starch solution will have a blue-black colour in the mixture but no changes in colour for maltose solution. When hydrochloric acid (HCl) is added to the starch solution‚ the color will

Dialysis of starch‚ glucose and sucrose Introduction: Research question: Does the dialysis tube only allow certain substances to pass through the pores because of their size? Dependent and Independent variables: Independent variables: The temperature of the classroom The size of the molecules The size of the pores in the tube The concentration of the indicators Dependent variables: The substance will either pass the pores of the tube or not The result will vary in darkness (color) Controlled

Mixed Schools is the optimum Coeducation or mixed-gender education is the integrated education of male and female students in the same environment‚ while unisex education is the education where male and female students attend in separate classes or in separate buildings or schools. In the past‚ mixed schools were not acceptable‚ but by the time it became popular. Mixed schools are better for students socially‚ and it also develops their educational skills and psychological things. Parents recommend

some weight training will most likely be required‚ but not to the point where you are training to be an professional athlete. Realize that weight training can only take you so far and really only the elite athletes fully understand that having an optimum sports nutrition diet is the key to taking their game to the next level. In laymen’s terms nutrition is the science of providing the athlete with not only the proper amount of food but the correct types of food. In addition‚ hydration is also crucial

Charlene Villanueva - Biology Charlene Villanueva - Biology Starch‚ Glycogen and Cellulose Independent Research A polysaccharide is a long chain of monosaccharide molecules‚ held by glycosidic bonds. They are usually not sweet in taste‚ insoluble in water and often do not produce crystals when water is taken out. Starch Starch is a complex solid carbohydrate‚ consisting glucose molecules held together by glycosidic bonds. It is a storage polysaccharide. They can be found in fruits‚ seeds‚ roots

temperature on amylase activity Introduction Amylase is an enzyme that catalyses the breakdown of starch into sugars. Amylases are found in almost all plants‚ animals and microorganisms. Large amounts of amylase occur in germinating cereals‚ and in the pancreas and saliva of higher animals. Aim The aim of this experiment is to find out the rate of reaction between amylase and starch in a range of different reaction temperatures. Hypothesis As the reaction temperature of amylase solution

Abstract α-amylase was immobilized covalently on iron oxide magnetic nanoparticles. The synthesis of magnetic nanoparticles was done by the coprecipitation conventional method. The chemical composition and particle size of the synthesized particles was confirmed via X-ray diffraction. Tyrosine‚ Lucien and chitosan and glutaraldehyde were investigated to make a covalent binding between the iron oxide magnetic core and the immobilized enzyme. Immobilization using chitosan and glutaraldehyde show
