The Effects of pH‚ Temperature‚ Enzyme‚ and Substrate Concentrations on Benzoquinone Production BIOL 2051 June 10th 2013 Introduction Enzymes are the ultimate catalysts of living things. Enzymes are made of proteins which are structured and directed by amino acids chains. Enzymes attract and fit substrate molecules to an active site. The active site binds the substrate molecules covalently to enzyme forming an enzyme-substrate complex‚ which catalyzes

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

predicted that the enzymes in the pineapple will denature when the temperature is changed. The prediction was partly correct. Pineapples have special enzymes that denature gelatin molecules. Which is the reason why the pineapple and gelatin test tube remained filled with liquid‚ instead of turning into jelly which gelatin does when it’s molecules are not disturbed. Why our hypothesis was partly incorrect was lacked depth in that when changing the temperature by heating the pineapple to 40C it actually

Enzymes play a vital role in helping our body function. They act as biological catalysts and help speed up reactions that would otherwise take long periods of time to naturally occur. Enzymes help lower the activation energy required for the reactants to reach the transitional state from which then they can form products. However‚ enzymes do not change the free energy of the reaction. Enzyme’s ability to catalyze reactions comes from the shape of the active site on the enzyme. Enzymes are hyper-specific
Premium Enzyme PH
Introduction Enzymes are proteins produced by living organisms to speed up the rate in which chemical reactions occur. This process can happen fast‚ slowly‚ or stop the chemical reaction all together depending on the temperature‚ pH and concentration. Catalase is one of the most common enzymes. It is found in living organisms and is used to break down hydrogen peroxide. This must happen because hydrogen peroxide is considered toxic to cells in the body. However‚ when catalase is used it breaks

1. Fill a shallow pan 3/4th full of water and place the glass tube into the water and make sure that the tube is covered with water and has no air bubbles. 2. Obtain 10 mL hydrogen peroxide and dilute it by adding 30 mL of distilled water. Place solution in a beaker and label as “25% Hydrogen Peroxide.” 3. Obtain 20 mL hydrogen peroxide and dilute it by adding 20 mL of distilled water. Place solution in a beaker and label as “1.5% Hydrogen Peroxide.” 4. Obtain 40 mL of 3% hydrogen peroxide‚ place

structures of cells but they act as enzymes in reactions of the body1. Enzymes are biological catalysts that lower the amount of activation energy needed in carrying out biochemical reactions1. Enzymes are responsible for almost every reaction that occurs in a cell and is named according to the substrate they specifically affect. An enzyme works best under optimal conditions pertaining to temperature‚ pH level and salt concentration1. In unfavorable conditions enzymes will become denatured and ineffective

Unit 6 Assignment 3 Duane Swarts ITT Technical Institute Group Theory SP2750 Mrs. Meadowlark 4 February 2014 Social exchange theory suggests that social behavior is the result of an exchange process. The purpose of this exchange is to maximize benefits and minimize costs. According to this theory‚ people weigh the potential benefits and risks of social relationships. When the risks outweigh the rewards‚ people will terminate or abandon that relationship. Social exchange theory suggests that

The Prickly Truth About Pineapples When you hear the word “pineapple”‚ what sort of imagery comes to mind? Many people will think of a round slice of pineapple sitting atop a holiday ham‚ garnished with a cherry. Others will picture enjoying a tropical cocktail from a curvy‚ elaborate glass‚ adorned with a miniature umbrella and a small chunk of pineapple hanging from the rim. However‚ it may surprise the majority of the population that pineapples are not native to the Pacific Islands. Even though
