I then decided on the range of results and temperatures I was to investigate. I decided to observe 20º‚ 30º‚ 40º‚ 50º‚ 60º‚ 70º and 80º. 3. Next‚ I label each test tube with the temperature to be investigated and then added 2.5cm3 of Trypsin solution. 4. I ensured that I cut the necessary pieces of film using a ruler and a pair of scissors

Biology coursework The aim of this experiment is to investigate the affect of pH on the enzyme amylase. The amylase is used to break down the polysaccharide starch. Amylase is a digestive enzyme classified as a saccharidase (an enzyme that cleaves polysaccharides). It is mainly a constituent of pancreatic juice and saliva‚ needed for the breakdown of long-chain carbohydrates (such as starch) into smaller units. Amylase is also synthesized in the fruit of many plants during ripening‚ causing them

Biology coursework: Substrate specificity in yeast AIM: To find out which substrate (glucose‚ starch‚ maltose‚ sucrose or lactose)‚ does yeast‚ the organism containing the enzyme‚ breaks down the quickest. Introduction: Usually‚ every enzyme has a specific substrate that is what we call the “lock and key” theory. We can try the reaction of an enzyme with different substrates and this enzyme will just work well with one of those substrates. One type of reaction catalyzed by enzymes is anaerobic respiration

Is gene therapy the most effective way to treat depression? What really is depression? The term ‘depression’ can be defined in two different ways: 1. Severe despondency and dejection‚ accompanied by feelings of hopelessness and inadequacy. 2. A condition of mental disturbance‚ typically with lack of energy and difficulty in maintaining concentration or interest in life.1 Majority of people believe that depression is somewhat trivial and is not regarded as a genuine health condition‚ but

provides students with an understanding of how ecosystems work. The topic continues by looking at whether climate change will lead to extinction of species or evolution by natural selection‚ and looks at the evidence for global warming and its effects on plants and animals. By the end of the topic students should appreciate how scientific understanding can make us aware of our responsibilities as stewards of the environment. Topic 6: Infection‚ immunity and forensics This topic starts

Intro I am going to do an investigation into what concentration of sucrose solution would cause “Incipient Plasmolysis”. Theory Plasmolysis is the result of a (in particular) plant cell which has lost vast amounts of water. When this happens‚ turgor pressure within the cell has decreased to the point where the cytoplasm of the cell membrane peels away from the cell wall. When this begins to happen it is called Incipient Plasmolysis and when the cytoplasm is almost completely gone it is call “full/complete”

Science Coursework Trypsin Investigation Aim I am going to prove that temperature effects the rate in which the enzyme Trypsin breaks down milk substrate into amino acids. Investigation "We strongly recommend the use of Vanish Stain Removal Tablets in conjunction with a 900 spin wash at 70°C" This was found on a milk carton of a well-known drinks company‚ Nesquick. The major food group constituent of milk is‚ of course‚ milk. For my Science Investigation‚ I am going to test different temperatures

The enzymes meant to digest your food and nourish you turned on you and started eating your body instead. In your bloodstream was a virus that was very specific to Alpha-1 Antitrypsin‚ the substance that inactivates Trypsin‚ Chymotrypsin‚ and Neutrophil Elastase. I know that’s all Chinese to you but you’ll soon understand. I decided to play a game with you‚ the same way you played games with me. I decided to trick your body into thinking it was doing what it was supposed

An experiment to investigate the effect of temperature on the rate of reaction of the Enzyme Trypsin. Aim: This investigation was on the effect temperature has on the rate that the enzyme trypsin hydrolyses its substrate‚ a protein found in milk (casein). This investigation was conducted under controlled conditions‚ the temperature being the changeable variable. Trypsin and its substrate (powdered milk which is a source of the protein casein) were heated in a water bath. The contents of the two
