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

INTRODUCTION Enzymes are a protein serving as a catalyst‚ a chemical agent that changes the rate of the reaction without being consumed by the reaction. Enzymes are proteins made up of long chains of amino acids. These form complex shapes. The enzymes are individuals‚ like the different players on a ball team‚ they have different specific structures and jobs. As one ball player may be very tall and one short‚ the specific different shape of the active site on an enzyme is unique and prepares it

Lab report nº4 The aim of this experiment was to observe the change of enzyme reaction with different concentration of solution. For this experiment we used potato enzymes (catalase) and hydrogen peroxide in concentrations of 100%‚ 80%‚ 60%‚ 40%‚ and 20% According to P.George: “When catalase is added to hydrogen peroxide‚ there is an initial rapid evolution of oxygen which lasts for about two minutes‚ depending on the peroxide concentration. After this‚ oxygen is given off at a steady rate which

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

Effect of temperature of the reaction: The effect of the temperature of the reaction on the activity of the purified enzyme was carried out by make the enzymatic reaction for 10 minutes at different temperature 25‚30‚35‚40‚45‚50‚60 and 70°C using an enzyme protein 0.1mg/reaction mixture and substrate concentration of 15 mg/reaction mixture‚ using a control of previously heated enzyme solution in the reaction. The data recorded in (table 27) and (figure 29) illustrate the effect of temperature of the

Discussion The primary purpose of this experiment was to determine the optimum temperature range for the activity of the enzyme lactase. Extreme temperatures can have a detrimental effect on enzymes; very hot temperatures can cause the denaturation in the enzyme‚ which is the loss of protein structure. This causes a change in the shape of the enzyme leading to its inability to perform its function. As previously stated‚ the alternate hypothesis read: the optimal temperature range for lactase activity
