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 it will break down the peroxide faster because yeast tends to rise

Reetika Kashyap September 20th‚ 2012 Enzyme Lab What is an enzyme? Enzymes are specialized protein molecules simplifying most of the body’s metabolic processes such as‚ supplying energy‚ digesting foods‚ purifying your blood‚ executing the body of waste products etc. Enzymes act as catalyst by speeding up the reactions that happen in our bodies and decreasing the amount of activation energy needed to break a complex down. A reactant is any given enzymatic reaction is called a substrate for that

Introduction: Biological organisms are classified uniformly in order to easily categorize and identify organisms. This classification‚ or taxonomy‚ uses the genus name followed by the species name‚ in Latin. By having a universal method of identifying bacteria allows for all scientists from any part of the world to identify the same species in an identical manner allowing for a precise of classification. Bacteria are distributed throughout the world in almost every conceivable habit. Bacteria are

(ii) Give an ionic equation to represent the neutralization reaction. Q2. Manganese (IV) oxide catalyses the decomposition of aqueous hydrogen peroxides. In an experiment 50.0 cm3 of aqueous hydrogen peroxide was mixed with 0.50 g of manganese (IV) oxide. The total volume of oxygen formed was measured every 10 seconds. The

CELL ANATOMY Microbodies Brief History Microbodies were first discovered and named in 1954 by Rhodin. De Duve chose the name of Peroxisome because of its relationship with hydrogen peroxide. In 1967‚ Breidenbach and Beevers were the first to isolate microbodies from plants‚ which they named Glyoxysomes because they were found to contain enzymes of the Glyoxylate cycle. Definition Any of the membrane-bound‚ ovoid or spherical‚ granular cytoplasmic particles containing enzymes and other substances

after a magnet. The spin was set to 700 rpm‚ and hydrogen peroxide was injected through a needle into the flask while spinning. Timing began as soon as the hydrogen peroxide was inserted. Once nine milliliters was reached timing stopped. The reaction flask was cleaned after every run.
