this experiment was to learn about enzymes and how to test for the effect of pH on catalase activity and to be able to tell if a reaction is an exergonic or endergonic process. Introduction Enzymes are made from amino acids‚ which are made from proteins. In order to make an enzyme‚ hundreds of amino acids are strung together in a very specific and unique order and eventually is folded into a unique shape. That shape permits the enzyme to carry out specific chemical reactions - an enzyme acts as

tissue Problem: To compare the denaturation of membrane of cells in the effect of mouth rinse of different brands and find out which brand of mouth rinse damages the membrane of cells most. Therefore ‚ the health risk of mouth rinse can be known. denaturation is used to describe protein only‚ not a membrane. --> destruction Hypothesis: The pigment in beetroot is permeable to the chemicals in the mouth rinse Principles: The plasma membrane is made up of protein and lipid molecules. These two

diffuse since it is small enough but the albumin is much too large to pass through the membrane. The experiment produced this result. Activity 2 1. Neither way requires ATP but facilitated diffusion requires carrier protein molecules for diffusion to occur. 2. By increasing the number of carriers more glucose can pass at a time increasing the rate‚ as predicted. 3. It won’t change since the concentrations are the same and the transport proteins are glucose carriers. The rate did not

2. Did Na+Cl- move through the 50 MWCO membrane? Activity 2: 1. Are the solutes moving with or against their concentration gradient in facilitated diffusion? 2. What happened to the rate of facilitated diffusion when the number of carrier proteins was increased? 3. In the simulation you added Na+Cl- to test its effect on glucose diffusion. Explain why there was no effect. Activity 3: 1. Which membrane resulted in the greatest pressure with Na+Cl- as the solute? Why? 2. Explain what

on the information given and the presence of necrosis‚ fibrosis‚ and cirrhosis she is more than likely in stage IV. What organ is being attacked? Describe this organ’s role in carbohydrate‚ lipid (including triglyceride and cholesterol)‚ and protein metabolism. Her liver is being attacked. With carbohydrate metabolism sugars enter the liver from the small intestine via the hepatic portal vein. The liver maintains the blood glucose level at about 90 mg glucose per 100cm3 of blood.

Which materials diffused from the left beaker to the right beaker Urea‚ NaCl and glucose diffused 5. Which did not? Why? Albumin‚ because it is too large to diffuse Activity 2: Simulating Dialysis 1. What happens to the urea concentration in the left beaker (the patient)? Its concentration gradient changes and causes it to move down 2. Why does this occur? It

The Renal Diet 1.The kidneys: * The kidneys are a pair of bean-shaped organs that lie on either side of the spine in the lower middle of the back. Each kidney weighs about ¼ pound. * It is important to keep the kidneys in good working order to allow them to work at an optimum level. * The main function of the kidneys is to remove waste products and excess water from the blood. The kidneys process about 200 l’s of blood every day and produce about 2 l’s of urine. * The kidneys

these medications. Alcoholic cirrhosis is charactered by the replacement of the destroyed liver cells with the scar tissue (Farrell & Dempsey‚ 2009‚ p.1167). The increased liver scar tissue result in the failure of liver function to synthesis protein‚ clotting factors‚ the substances and manifestation of portal hypertension (Farrell & Dempsey‚ 2009‚ p.1168). In liver cirrhosis‚ the live tend to be large and its cells loaded with fat‚ that it causes the liver become firm and sharp edge noticeable

If when we test each substance and the color changes‚ then that product has one or some of sugar‚ starch‚ protein‚ or lipids in it. Methods: As suggested in the book on page 36.
