THE EFFECT OF CATALASE ON HYDROGEN PEROXIDE The aim of the experiments is to see if increasing the surface area of the enzyme Catalase‚ affects the relative activity of the substrate Hydrogen peroxide. Then to observe and measure the effect the Catalase has on the chemical breakdown of the hydrogen peroxide. My theory is if you keep increasing the surface area of Catalase‚ the more active sites are available to join with the substrate causing an increase in the breakdown of the hydrogen peroxide

are steroids a fair way to be the best you can be physically? The documentary “Bigger‚ Stronger‚ Faster” attempts to answer this question. Are steroids fair? That has always been the huge question in competitive sports such as major league baseball‚ the NFL‚ bodybuilding‚ and olympic sports. What steroids do is put more testosterone in your body to promote muscle growth to a high degree. Now why should that be fair to get much stronger without your opponent knowing that you’re taking a supplement

Abstract: Enzymes‚ molecules that speed up chemical reactions‚ are specific to one substrate. In this experiment the substrate hydrogen peroxide and the enzyme catalase will be used. The higher the concentration of potato extract‚ or catalase‚ the faster the reaction and the more substrate present will result in a decrease in the time of the reaction. The amount of concentrations of enzymes and substrates are changed to determine if the reaction is further catalyzed by a greater concentration of

The Effect of Temperature on the Enzyme Catalase Stephen Francis Biology 183 Abstract This experiment was performed to determine the resultant effect of temperature change on the reaction between the enzyme catalase and hydrogen peroxide. This experiment was performed by measuring and comparing the amount of oxygen bubbles produced and the absorbance of the catalase and hydrogen peroxide solution over time at room temperature‚ 2°C‚ 50°C‚ and 60°C. The overall result of this experiment proved

John’s ship finally arrived in New York and he was exhausted. He and his family traveled to America because of the potato famine that was happening back home in Ireland. The first task he needed to do was find a place to live at with his family; he realized that the decent houses and apartments were out of his budget. He only had money for the crowded and unhygienic apartments‚ if they could be called that. After John picked a “room” out‚ he went to search for jobs. While he was out looking for work

decreasing the energy of activation. The main function of enzyme catalase is to convert hydrogen peroxide (H2O2) in our bodies into oxygen and water. This can be visually seen when hydrogen peroxide is put on a wound and the peroxide bubbles. Enzymes can also be found in plant cells and fungi. (Huston.) In this experiment we test the many variables that can change the rate of this reaction such as temperature‚ concentration levels of enzyme catalase and pH values. We are able to track these changes using

Potato Battery Chapter I: Introduction I. Background of the Study Do you have like 500 unused sacks of potatoes and don’t know what to do with it? Does your low class battery always die out on you at the exact moment you look at the last digit of you clock? If you answered yes‚ then here is the solution to your problem! Potato batteries are designed for you! So why do you spend so much money in buying new batteries for your digital clock if you can use the alternative resource. II. Statement

Along the way‚ scientists discovered that the popular staple of many people’s diets may also have potential to help power it as well. The potato is starchy‚ tuberous crop from the perennial nightshade . The word "potato" may refer either to the plant itself

Arnesh Kaewloyma 9/30/14 Enzyme Catalase under optimum conditions‚ speeds up the decomposition of hydrogen peroxide The students have studied that Hydrogen peroxide is a jeopardy to metabolism if it’s not obliterated. Enzymes are proteins produced by living cells of that act as catalysts which affects the rate of biochemical reaction by speeds up the breakdown of hydrogen peroxide into water and oxygen gas. The students have formed a hypothesis toward this experiment. If the speed of
