factor. I believe that the optimal temperature for the enzyme sucrase will be 37°C because that is the point where the temperature increases the rate of reaction to its greatest point without denaturing it. For the pH test‚ I think that the optimal pH for sucrase will be the pH of 7 because it is neutral so it won’t affect the charge in a negative or positive way. For the denaturation test‚ I think that the optimal treatment for the enzyme is when both the enzyme and substrate are untreated. For the

Investigation on the effects of Temperature‚ pH levels‚ and Enzyme Concentration on the reaction rate of the Decomposition of Hydrogen Peroxide by Catalase The purpose of this investigation is to figure out how temperature‚ pH‚ and enzyme concentration affect the reaction rate of an enzyme. It’s important to understand how certain factors affect enzymes because of their crucial role in the metabolic processes of life. Enzymes lower the activation energy necessary for a chemical reaction to

Biology Enzymes IA Design Introduction: Enzymes are globular proteins‚ they are responsible for most of the chemical activities of a living organism. They act as catalysts‚ substances that affects the reaction of other substances without being destroyed or altered during the process. They are extremely efficient in the body system of living organisms‚ one enzyme may catalyse over a thousand chemical reactions every second. But there are certain conditions that need to be fulfilled in order for the
Premium Enzyme Oxygen Catalase
I was testing different temperatures and how it affects the time catalase takes for it to break down peroxide. The problem that i was investigating is how does temperature affect the time it takes for catalase to break down peroxide. My independent variable for this lab was the temperature of the solution the enzyme is in. My dependent variable in this experiment was rate of reaction or the amount of time it takes to sink and rise. My hypothesis is that if the temperature is higher than 37℃‚ then

EFFECT OF ROOM TEMPERATURE ON THE BURN-RATE OF A CANDLE BURNS Have you ever wondered whether a candle burns more quickly on a hot day‚ than on a cold day? Or is it the other way around? This science fair project was carried out to compare how quickly a candle will burn at different room temperatures. The experiment was done by measuring how much of a candle will melt in 30 minutes when placed in an environment with surrounding temperatures of 20°C‚ 25°C and 30°C. Hypothesis A candle in a colder

RESEARCH PAPER ON BIOLOGICAL ACTIVITY OF ACTINOMYCETES ................ ABSTRACT: The microorganisms are ubiquitous in nature. They are found in probably every environmental condition present on earth. Actinomycetes were originally considered to be an intermediate group between bacteria and fungi but now are recognized as prokaryotic organisms with high G+C (>55%) content in their DNA. Our project aim is to evaluate some biological activities of Actinomycetes like:

Enzymes in Living Tissues Purpose: The purpose of the lab was to analyze the enzymes in living tissues‚ represented by the pieces of liver. Also‚ hydrogen peroxide was used to demonstrate these effects. Storyboard: Materials: 2 50 mL beakers 10 mL graduated cylinder 3% hydrogen peroxide solution Hot water bath Lemon juice or HCl Fresh liver Forceps Procedure: Measure 10 mL of hydrogen peroxide and record its temperature. Pick the liver up with the forceps and

Barley Alpha Amylase with Starch at Specific pH ’s and Temperatures Page 1 Abstract Enzyme ’s are used as catalysts in certain reactions. They help lower the activation energy needed for the reaction to go to completion. At optimum temperature and pH the amount of collisions of substrate and enzyme is at its highest‚ any deviation from the optimum temperature and pH will result in the denaturization of the enzyme. The purpose of this experiment is to find the optimum temperature and pH for

The effect of time on enzyme reaction. Abstract: In this lab investigation we will observe how the amount of hydrogen peroxide is affected by catalase over time. The enzyme was added to 10 mL’s of hydrogen peroxide and observed over time to determine the relation between time and enzyme activity. The hypothesis stated that as time increased substrate would decrease. Therefore I predicted that at 60 seconds‚ there would be the least amount of H2O2. The enzyme activity mirrored my predictions

Enzymes: Food & Nutrition What are enzymes Enzymes are a type of protein produced by a living organism used to catalyze chemical reactions in cells. These reactions allow the cell to build things or take things apart as needed in order to grow and reproduce. How do enzymes work - in steps 1) Substrate floats near enzyme 2) Substrate and enzyme connect – which breaks it into products 3) Products are released ex) BreadFast & Co.’s use of enzymes The company uses many different
