Glucose Oxidase and Its Various Uses Aaron Truong Since glucose oxidase has an end product called hydrogen peroxide‚ which is a harmful substance to bacteria‚ it can be used to fight bacteria‚ or sterilize objects (can have various uses such as in hand sanitizers‚ toothpaste‚ soap‚ etc)‚ not just biosensors. Another key part in the reaction would be C6H12O6‚ or glucose. Glucose oxidase can be applied to diabetics as mentioned earlier‚ as biosensors work by "keeping track of the

reaction than the other test tube. Which simply contained 10 mL of 3% hydrogen peroxide. The factor that affected the reaction rate was that the manganese was seen as a catalyst. The reason collision theory relates to this experiment is due to the fact that the catalyst creates a higher activation energy and this causes more collisions‚ which increases the reaction rate. In the second experiment‚ the Alka Seltzer tablet was

Yeasts’ capability of undergoing ethanol fermentation‚ its ability to ferment other sugars and artificial sweeteners‚ and how lactase influences yeasts ability to use lactose as a food source Kristina Naydenova Father Michael Goetz Purpose Part A: To investigate whether yeast has the ability to ferment glucose to produce carbon dioxide gas and ethanol. Part B: To investigate whether yeast has the ability to ferment other sugars and artificial sweeteners and how lactase influences their

“Respiration” and “Photosynthesis” All life depends on two chemical reactions “Respiration” and “Photosynthesis”. These two processes are quite crucial because they are a source to nearly all life on Earth. Both of these processes are quite similar yet differentiate vastly. In this essay I’ll be comparing and contrasting “Photosynthesis” and “Respiration”. I’ll start by discussing what actually happens

is to determine how different factors affect the digestion of starch. Starch is a type of complex carbohydrate with large polysaccharide molecules that are made up of hundreds of glucose subunits. The digestion of starch begins in the mouth with the enzyme amylase and continues in the small intestine. Maltose‚ a disaccharide‚ breaks down the large polysaccharide molecules. Maltase‚ also found in the small intestine‚ splits each maltose molecule in to two glucose molecules that can

Analysis • Error Bars Analysis Evaluation • Improvement Assessment • Improved Experiment. • Reliability References Introduction: For this data analysis project‚ I conducted and experiment to investigate how the concentration of an acid affects the rate of the reaction. I have set up the experiment’s equipment as shown on figure 1. As you can see by figure 1‚ I have used the reaction between sodium thisoulphate solution and hydrochloric acid (HCL) to come up with results that

The Effect of Boiling on the Rate of Aerobic Respiration of Germinating Peas Abstract Aerobic respiration is an enzyme mediated process during which glucose is used to make ATP to fuel the cells energy needs. Germination is one of such processes that make use of aerobic respiration and because certain factors can affect aerobic respiration‚ it would also affect germination. In this experiment‚ we examined the effects of boiling on the rate of aerobic respiration of germinating peas. Unboiled

Dialysis of starch‚ glucose and sucrose Introduction: Research question: Does the dialysis tube only allow certain substances to pass through the pores because of their size? Dependent and Independent variables: Independent variables: The temperature of the classroom The size of the molecules The size of the pores in the tube The concentration of the indicators Dependent variables: The substance will either pass the pores of the tube or not The result will vary in darkness (color) Controlled

This experiment analyzes the effects of how temperature affects bacterial and fungus amylase and also discovers the optimum temperature for these enzymes. The amylase was mixed with starch at temperatures of 0℃‚ 37℃‚ 57℃‚ and 90℃. Iodine was added to each mixture and colour changes in each case. Bacteria amylase was found to be effective at 55 0C as the temperature dropped drastically from 4.58℃ to 2.33℃. This shows that the amylase catabolized a lot of starch hence little is left which cannot turn

oD 4.1 Respiration Why organisms undergo respiration What is respiration and why do we need it? Respiration is the process whereby energy is released from food molecules (most usually glucose). It takes place inside living cells‚ both eukaryotic and prokaryotic. The process takes place inside the cytoplasm and the mitochondria. Energy is used to synthesise adenosine triphosphate (ATP)‚ which acts as a short-term energy store in cells. All living organisms need energy to drive their
