Pineapple Jelly Enzyme Lab Discussion

After completing the Pineapple Jell-O Enzyme lab, the final results were that the canned pineapple formed the jelly while the fresh pineapple did not. Pineapple In order for this to have occurred, there has to be a comparison between fresh and canned pineapple in terms of their physical and chemical properties. The physical properties of fresh pineapple are that it is sweet, ripe and raw. These properties make fresh pineapples very healthy and delicious to eat. The chemical properties of fresh pineapple are that it contains bromelain, vitamin C, antioxidants, carbohydrates and helps defend the immune system. Bromelain is an enzyme that “promotes the digestive process and helps to break down proteins in foods” (Jomard, 2007). It also breaks “collagen, preventing Jell-O from gelling” (Helmenstine, 2013). It is also used as an anticoagulant, which prevents blood clotting. Fresh pineapples also have “anti-inflammatory properties, which make it useful to reduce pain” (Botanical-online, 2013). Vitamin C is “important to the health of your immune system and enables your body to repair and grow tissue” (Cespedes, 2011). The physical properties of canned pineapple are that they are sweet and “it can be canned in various forms – slices, chunks or crushed” (Dalal, 2008). Canned pineapples are not as fresh or nutritious as fresh pineapples. The chemical properties of canned pineapple are that it is used in gelatin desserts. It does not have bromelain because of the canning process. Fruits that might have the same anticoagulant properties as pineapple are “cherries, cranberries, blueberries, grapes, strawberries, tangerines and oranges” (Simmons, 2012). Each fruit does not provide the same type of action because each provides different types of nutrition. Chefs use chillies to make pineapple jellies is because to add some flavor in the jelly and also that chilli is

    Purpose/Problem: There are four parts to the Enzyme Catalyst lab - Activity A, B, C, and D. In activity A, the characteristics of enzyme actions will be observed. The main purposes are to determine the rate of an enzyme catalyzed reaction, to study the characteristics of an enzyme mediated reaction, and to observe the effect of heat on enzyme activity. The purpose of activity B is to use the Titration Protocol to determine the initial amount of H2O2 present in a solution. The amount will be the baseline for activities C and D. The purpose of activity C is to determine the rate at which H2O2 spontaneously decomposes when exposed to room temperatures and ambient light for 24 hours. The purpose of activity D is to determine the rate at which catalase decomposes H2O2. After adding H2SO4 for different time lashes, etc., the resulting data will be graphed at which the catalase decomposed by catalase.…

Lower temps make it so that the enzymes and substrates attach at a slower rate, diminishing product formation.…

    The results of our experiment showed the solutions in both tube 1 and tube 2 increasing in absorbency in the first eight minutes but then tube 1 continued to increase while tube 2 began to balance out. Tube 3, our blank, managed to stay at 0nm the entire twenty minutes. From this data, we can conclude that our hypothesis was supported that EDTA had a greater change in absorption over PTU.…

    Enzymes are proteins that are involved in all the chemical processes in living things. As they are made of proteins they are affected by pH and temperature. Enzymes are catalysts; they speed up chemical reactions without being changed themselves. Digestive enzymes speed up the breakdown of large 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.…

    Enzymes are catalysts that speed up chemical reaction but are not themselves consumed or changed by the reaction. The cell’s biological catalysts are proteins. Proteins are made up of one or more polypeptide chains that are folded to make an active site, an area in which a material to be acted on by the enzyme, called the substrate, will fit. The temperature,pH, the concentration of enzyme, and the concentration of substrate all affect the activity of the enzyme and the rate of the reaction.…

    Our results showed that the reaction rate and concentration of substrate are proportional. Why this happens is interesting. A reaction is the change of the substrate into a new and different thing, called the product. The collision theory states that reactions happen as molecules collide, but they must collide at the correct orientation so that the activation sites on the molecules will match up. If you can increase the number of molecules in a reaction, you will also increase the chances of having the molecules collide. When we increased the concentration of substrate we increased the number of molecules, and thereby increasing the chances of the molecules colliding. So increasing the concentration of the substrate increased the rate of the…

    Enzymes are a protein serving as a catalyst, a chemical agent that changes the rate of the reaction without being consumed by the reaction. Enzymes are proteins made up of long chains of amino acids. These form complex shapes. The enzymes are individuals, like the different players on a ball team, they have different specific structures and jobs. As one ball player may be very tall and one short, the specific different shape of the active site on an enzyme is unique and prepares it to mix with a certain substrate. Without enzymes, the process of metabolism would be hopelessly slow. The reactant an enzyme acts on is referred to the enzyme 's substrate. The enzyme will combine with or to its substrate. While the two are joined, the substrate is converted to its product by catalytic action of the enzyme. There is an active site of the enzyme molecule which is a restricted region that actually attaches to the substrate. Usually the active site is formed by only a few of the enzyme 's amino acids, the rest is just the framework that reinforces the active site. In an enzymatic reaction, the substrate enters the active site then is held in place by weak bonds. Now the enzyme does its work and first changes shape so it can hold onto the substrate. Next the substrate is changed to its product, the product is released and the enzymes active site is ready and waiting for another molecule of substrate.…
