Investigation into how pH levels affect Catalase activity in potato samples – (enzymes) Introduction: The aim of this investigation is to understand and monitor the effects pH levels have on catalase activity within controlled potato samples. Catalase is a type of enzyme that is found widespread among organisms that grow in the presence of oxygen (almost all living things) its specific use is to speed up the decomposition of Hydrogen peroxide (H2O2) within cells. Hydrogen peroxide is a bi-product

Computer Enzyme Action: Testing Catalase Activity 6A H2O2 is toxic to most living organisms. Many organisms are capable of enzymatically destroying the H2O2 before it can do much damage. H2O2 can be converted to oxygen and water‚ as follows: 2 H2O2 → 2 H2O + O2 Although this reaction occurs spontaneously‚ enzymes increase the rate considerably. At least two different enzymes are known to catalyze this reaction: catalase‚ found in animals and protists‚ and peroxidase‚ found in plants. A great

Dependent: the reaction rate Control variable: temperature and amount of substrates and enzymes added. Materials: Phosphate Buffers Beaker Catechol Potato Juice Parafilm Test Tubes Procedure: To study the effect of temperature: 1. Three different test tubes where filled with 3mL of phosphate. 2. They were set in three different temperature settings. First tube was

Enzyme Activity Over Different Concentrations and Effects The goals of this experiment were to examine the effectively of enzymes on samples of different enzyme concentrations and substrate concentrations. In addition‚ the experiment tested how effective enzymes are on samples of pH levels and temperature levels. A. Effect of Enzyme Concentration Hypothesis: With half as much enzyme concentration then the reaction rate will be half as much than when the enzyme concentration is equal

Solutions Solutions are a combination of solvents and solutes. When a solute dissolves into a solvent‚ the combined product of the two reactants is called a solution. The definition of a solute is the reactant that’s being dissolved. The only difference from a solute and a solvent is that the solvent is the one that’s doing the dissolving. Molecules randomly flow in all directions until there is an equal concentration throughout the solution. The dissolving process can vary depending

Mixtures and Solutions can often become confusing because solutions are mixtures‚ but not all mixtures are solutions. A mixture can either be homogeneous or heterogeneous. A homogeneous mixture is where the mixture’s components are distributed uniformly within the mixture. A heterogeneous mixture is where the components are not uniform. Mixtures can either be miscible or immiscible‚ the difference being whether or not the mixture forms a homogeneous mixture or not. In a solution a solute is soluble

EXPERIMENTAL DETAILS All chemicals used were Merck reagent grade. Solutions were formulated with chromium sulfate (Cr¬2(SO4)3.6H2O) as chromium source in the quantities presented in (Table 1); Solutions were heated to 60°C for three hours during complexation reaction as in [29]‚ and pH was adjusted to 3 units without HCl or NH3 . Table1- electrolyte and electrodeposition parameter The coatings were deposited on a 1 x 1.5 cm2 cooper plate sample. Preparation for all specimens was as follow: Firstly
