Raisha Miggins Lab 5: Osmosis Purpose The purpose of this lab was to explore the concept of Osmosis using dialysis tubing and different concentrations of sucrose solutions‚ and to help one better understand what happens to cells when they are exposed to solutions of differing tonicities. Hypothesis If the four dialysis tubes containing different concentrations of sucrose are all placed in their appropriate solutions for 20 minutes‚ then my predictions are as follows: The 1% in 1% sugar solution

Dark Purple Proteins are present with purple peptides 3 Pepsin Purplish blue‚ darkish blue Proteins are present with purple or black colored peptides 4 Starch Light blue‚ really clear Possible little protein with clear peptide or no protein at all Our results are correct because water and starch should not contain protein (starch is a polysaccharide but not of an amino acid) and therefore remained blue unlike Albumin and Pepsin which do contain proteins causing them to turn into a different

QUESTIONS 1. What are other sources of glycogen? Of starch? a. Other sources of glycogen- Aside from the liver‚ it can also be found in skeletal muscles (for energy during strenuous exercise). It also occurs in tissues including adipose tissues‚ heart muscles‚ kidneys and the brain. It is also found in yeast‚ bacteria‚ fungi‚ molds and algae‚ oysters‚ and shellfish. b. Other sources of starch- Foods that are high in starch include breads‚ grains‚ cereals‚ pasta‚ rice‚ potatoes‚ peas

water‚ albumin solution‚ and starch solution. If the protein is present‚ then the biuret will change to a violet color. Authors: Eliza Koundry and Jody Cote Eliza was in charge of adding equal amounts of biuret reagent to the distilled water‚ albumin solution‚ and the starch solution. Jody was in charge of recording any color changes in the appropriate tables. Introduction: Testing for protiens: For solutions we used; water‚ albumin‚ and starch. We added equal amounts

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 and starch solution increase‚ the reaction rate of amylase and starch will increase

Discuss and interpret diagnostic tests related to Renal self care deficits. Discuss social‚ economical‚ cultural factors that impact an individuals self care. Use effective teaching and therapeutic communication skills with parents ‚patients families

found in saliva that acts on starch to begin the digestion process (Stick and Williams‚ 2009). Amylase acts on starch by breaking off maltose (C12H22O11) molecules from the end of starch chains (Di Giuseppe‚ 2002). Every time a bond is broken in a starch chain‚ a water molecule is consumed. This process is referred to as a hydrolysis reaction which requires water to digest a substrate‚ in this case starch (Walsh‚ 2002). Phosphorylase is also an enzyme that acts on starch by removing glucose molecules

ventilator‚ which forces air into the lungs of a patient who cannot breathe on her own. The second type is a pacemaker which is used for those who have irregular heartbeats‚ or for those who suffer from an abnormality of the blood vessels. Next‚ there are dialysis machines‚ which are most commonly used for patients who suffer from renal (kidney) failure. A ventilator works by forcing warm‚ oxygenated air into the lungs while removing carbon dioxide. A plastic tube is inserted through the mouth and

food molecules into smaller ones so that the blood can absorb them. Enzymes turn a large starch molecule into thousands of tiny glucose molecules. Enzymes end in ’ase’. There are thousands of enzymes in our body but each enzyme is only specialised to do one thing‚ for example carbohydraise enzymes digest carbohydrates‚ protease enzymes digest protein. Prediction I predict that the amylase will digest the starch the best and the quickest at around room temperature‚ (35 C-45 C). I have come to this
