An investigation to compare the reaction rates between potato and hydrogen peroxide against liver and hydrogen peroxide through loss in mass. Background information: Catalase is an enzyme that is found in all cells. This means that it is an intracellular enzyme. And enzyme is a biological catalyst. A catalyst is some thing that speeds up a reaction without being changed itself. Because of this enzymes and catalysts can be used again and again. Enzymes are protein chains that have a primary‚ secondary

Sweet Potato Pie Eugenia Collier From up here on the fourteenth floor‚ my brother Charley looks like an insect scurrying among other insects. A deep feeling of love surges through me. Despite the distance‚ he seems to feel it‚ for he turns and scans the upper windows‚ but failing to find me‚ continues on his way. I watch him moving quickly—gingerly‚ it seems to me—down Fifth Avenue and around the corner to his shabby taxicab. In a moment he will be heading back uptown. I turn from the window

GCSE - Human Physiology and Health An experiment to investigate what affect sucrose solution has on potato tissue. Background Osmosis is the movement of water molecules‚ across a partially permeable membrane from a region of high concentration of water to a low concentration of water molecules. A partially permeable membrane is a membrane with holes in it small enough for only water to go through it. Big molecules like glucose cannot fit through it. Osmosis allows plants to take in water

Store-check Report I. Introduction Potato chips is the most popular and common snack for Filipinos‚ both children and adults. The objective of this study is to deliver to customers the different pricing trends of the producers of potato chips to its market. One of the leading brands that is fast-selling is Jack n’ Jill’s Piattos. This potato chip brand runs through the market in many countries including Thailand‚ Malaysia‚ China‚ Indonesia and Vietnam for 46 years (Source: http://www.universalrobina

SUMMARY‚ COMCLUSSION AND RECOMMENDATION The main objective of the study was to develop sweet potato cookies. Specifically‚ it sought to (a) evaluate the sensory qualities of sweet potato cookies in terms of appearance‚ odor texture and taste. (b) determine the most suitable treatment based on general acceptability. (c) determine if there is a significant difference on the proximate composition between control and the most acceptable treatment in terms of moisture‚ ash‚ crude fat‚ and protein

Digital Balance used to measure the mass of the potato strip before and after osmosis. Time should be kept constant when the potato strip is put into the solution Hypothesis: The mass of the potato strip will increase in water and dilute concentrations of sucrose depending on the concentration within the cell. When the concentration of the sucrose solution outside the cells of the potato strip will be less‚ the mass of the solution will increase as water molecules from outside will diffuse into

added 5ml of a different solution to each test tube. After that‚ we added 3 drops of iodine to each solution. Finally‚ we jotted down the results and colors of each tube. The experimental group is 5mL of each of these solutions: onion juice‚ potato juice‚ sucrose‚ glucose‚ distilled water‚ reducing sugar‚ and starch. There is no control group because all the solutions are being experimented on. Iodine is the independent variable because you control how many drops of iodine are put in each solution‚

obesity percentages. Sucrose is the leading added sweetener in in the manufacture of foods in the Unites States and is the biggest source of fructose. Sucrose and high fructose corn syrup (HFCS) are metabolized identically and react the same way to insulin‚ leptin and ghrelin. Sucrose is indifferent from HFCS in causing obesity. Compared to glucose‚ sucrose is extracted directly from the liver while glucose goes directly to the bloodstream causing larger sugar spikes. HFCS and sucrose have an identical
