INVESTIGATING THE EFFECT OF TEMPERATURE ON THE RATE OF ENZYME ACTIVITY. To investigate the effect that temperature has on enzyme activity I am going to use the enzyme amylase‚ which is used as a biological catalyst to break down starch‚ which cannot pass through the gut wall due to the size of the molecules‚ into smaller ones. Amylase is a carbohydrase‚ which converts starch to simple sugars in the Salivary Glands. Three features of all enzymes are: They are always proteins. They are specific

Enzymes Reactions to Changes in Substrate and Inhibitors Benjamin J. Mora Coronado University of Texas Rio Grande Valley at Edinburgh Abstract Purpose for the experiments was to test the enzymes in various scenarios and see how changing this would affect the rate of reaction. The enzyme source used in the experiments was Turnip Extract. Concentrations of Turnip extract for activity 1 where o.5ml‚ 1.0ml‚ and 2.0 ml as for the rest of the activities 2 Through 4 stayed at a consistent concentration

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

Temperature affecting enzyme activity Aim: To see how temperature can affect enzyme activity Prediction:-I think the one that will work best will be the rennin placed in milk at 37oC My independent variable will be the temperature My dependant variable will be how thick the milk becomes The equipment I need is milk‚ 5 test tubes‚ rennin‚ water bath‚ boiled rennin‚ a glass rod and a stopwatch Introduction: Rennin is an enzyme found in the stomach‚ its function is to solidify milk. We

Enzyme Controlled Reactions 1) Describe the relationship between substrate concentration and the initial reaction rate of an enzyme-catalyzed reaction. Is this a linear relationship? What happens to the initial reaction rate as substrate concentration increases? A) The relationship between the substrate concentration and the initial reaction of an enzyme-catalyzed reaction is very productive‚ but is dramatically affected by the pH level of the given solution. The most productive pH level is

Practical Report The Effect of Temperature on Enzyme Activity Aim: To investigate how temperature effects the enzyme catalase. Hypothesis: If the temperature of water is increased then the enzyme will react quicker to form oxygen and water‚ when compared to cold water. Purpose: To design and conduct a plan of a practical about the effects of temperature on enzymatic activity with a partner. Introduction: An enzyme is a protein‚ which speeds up a specific chemical reaction without altering the products

Temperature Affecting Enzyme Activity Introduction The basic properties of life revolve around chemical reactions. Without the presence of enzymes some of life’s processes would not come so easily. Enzymes are basically proteins‚ which have specific shapes for different substrates. Enzymes change the rate in chemical reactions. It does this without having to change its own shape‚ which makes enzymes different from other proteins. A common enzyme that we have is catalase‚ which breaks down

The purpose of this lab is to determine the rate of reaction under different circumstances. Different variables will be manipulated to discover their effects on a particular reaction. Changes in temperature‚ pH‚ and enzyme concentration are examples of factors that have the potential to affect the initial rate of an enzyme catalyzed reaction in a controlled experiment‚ whether it be speeding the reaction up or slowing it down. Part I of the experiment establishes a baseline that can be used to compare

Investigating the effect of pH on the activity of the enzyme catalase. Introduction Hydrogen peroxide (H2O2) is a very pale blue liquid which appears colourless in a dilute solution‚ slightly more viscous than water. It is a weak acid. It has strong oxidizing properties and is therefore a powerful bleaching agent that is mostly used for bleaching paper. Catalase is a common enzyme found in all living organisms. Its functions include the conversion of Hydrogen Peroxide‚ a powerful and potentially

The environmental factors that effected the rate of enzyme reactions were the enzyme concentration‚ pH‚ and temperature. These environmental factors help enzymes break down the poisonous chemicals into harmless substance. When we tested the liver with 2ml of hydrogen peroxide for a normal reaction it showed that it was exothermic. We added more hydrogen peroxide and the reaction rate of the liver was 3. We learned that the catalase is reusable because the liver reacted both times when we put in
