20th‚ 2012 Enzyme Lab What is an enzyme? Enzymes are specialized protein molecules simplifying most of the body’s metabolic processes such as‚ supplying energy‚ digesting foods‚ purifying your blood‚ executing the body of waste products etc. Enzymes act as catalyst by speeding up the reactions that happen in our bodies and decreasing the amount of activation energy needed to break a complex down. A reactant is any given enzymatic reaction is called a substrate for that specific enzyme. The place

Enzyme Catalase Activity in Reaction with the Substrate Hydrogen Peroxide Abstract We performed these experiments to observe the effects of enzymes on the rate of reactions. We tested and compared the activity of the enzyme catalase on the substrate H2O2 in various states and percentages‚ and observed the absorption values of the enzyme-substrate relationship at different concentrations. Our results show that the more substrate available‚ the quicker the reaction will happen except in one test

Digestion and Enzymes – APP. Hypothesis: The enzyme‚ Amylase which is used to break down carbohydrates will work the best when heated at 40°C. Also‚ as the temperature increases the reaction rate of amylase increases too. However‚ the reaction rate of amylase will start decreasing when the temperature reaches the enzyme’s optimal temperature. Many enzymes are specific for a certain substrate. For example‚ lipase is a specific enzyme for fat substrates and protease‚ a specific enzyme for protein

hypothesis. Therefore‚ the meteorites and the magnetic fields all help scientist discover the interior of the Earth. The first thing scientist studied was the meteorites as they studied they try to find facts from the Earth’s past. The scientists studied the meteorites to find facts from the past because earth’s facts of how it was formed was almost lost when the earth has changed. “The scientist took 9 samples in attempt to learn more about how the Earth changed from it’s earlier formation of

Effects of Using Laptops in Classroom Laptop‚ a personal computer that is designed for mobile use and small and light enough to sit on a person’s lap while in use‚ has been well developed in technology. Because the use of computer or a laptop has been exceedingly increased as time passes‚ Manufactures bring out items such as netbook or iPad‚ and try to come with better technology to make it more efficient for people to carry around and use it. This also increased many college students to use

Introduction How does changing the surroundings of enzymes affect their reaction rate? The purpose of the experiment is to determine how different abiotic conditions affect the rate at which enzymes accelerate/cause reactions In this lab students measured the height of the foam after catalysis between catalase (enzyme) and 7 other (solutions) to determine which solution had the fastest reaction rate.. The control variable of the experiment would be the solution of only hydrogen peroxide‚ water

What was the effect of photography on painting in the nineteenth century? The photograph was developed in 1839 simultaneously in England and France by Talbot and Daguerre. That is the technique of chemically fixing of an image produced by exposure to rays of sun. William Fox Talbot was an English scholar and scientist who developed the negative and positive process. He used sensitive paper soaked in sodium hyposulphite called calotype. This became the basis for all subsequent photography. Photography

What effect does temperature have on the oxygen production of enzymes in an animal’s liver? A temperature which is too high would be able to produce little to no oxygen because of the extreme temperature. Just like a temperature too high‚ a temperature which is too low would also produce little to no oxygen for the same reason. Animals that have livers are considered warm-blooded‚ with very warm temperatures; therefore it would make sense for a warm temperature to produce the most oxygen; but one
