was designed to investigate the effects of temperature on reactions between the enzyme catalase found in animal tissue with the substrate H2O2. The hypothesis stated that an increase in the temperature of the substrate would create a subsequent increase in the rate of reaction between the enzyme and the substrate. This hypothesis was tested by immersing 1cm cubes of animal tissue (sheep liver) which contained the enzyme catalase into the substrate (H2O2 ) mixed with detergent which foamed showing a

Catalase Enzyme Lab Samiya Hussein March 9‚ 2012 Introduction In order to receive the necessary amounts of energy required for daily function‚ the digestive system must break down proteins‚ fats and carbohydrates. In doing so‚ the body produces poisonous chemicals; however‚ the cells aren’t harmed. This is because enzymes are used to break down these chemicals. The name of the enzyme that was the main focus of the lab is catalase. Catalase is responsible for catalyzing hydrogen peroxide

Biology101 McDowall 10/29/2012 Escherichia Coli “The Bacterial Beast” E.coli or binomial name Escherichia coli was discovered by a German pediatrician named Theodore Escherich in 1885. Dr. Escherich originally named the bacteria‚ bacillus communis coli. After the demise of Dr. Escherich the intestinal bacteria was then named Escherichia coli after the late doctor in 1919. The bacteria Escherichia coli are classified as follows. Domain- Bacteria Kingdom- Eubacteria Phylum- Proteobacteria

Eucalyptus and Colloidal Silver. Obtain two nutrient agar plates and using a permanent marker draw four quadrants on the bottom of each agar plate. Using a sterile pipet transfer 250 ml of E. coli broth to the middle of each petri dish and evenly spread bacterial culture around the agar plate. Cover and allow the culture to soak into agar for at east 15 minutes. Using sterile forceps‚ carefully place one filter disk from designated sample into the middle of each

Life is what you and you alone make of it! What is your view? I believe that we can make our lives into what we want them to become if we have enough drive and reserve to achieve our goals. Our lives are our own‚ waiting for us to take them and mold them into exactly what we want. However‚ our lives are very much influenced‚ affected‚ and controlled by the people around us. Friends‚ parents‚ society‚ and even ourselves‚ can inhibit our hopes and dreams just as much as they can help us achieve

This experiment was performed in order to analyze the effects of pH‚ enzyme concentration‚ and temperature on the catalytic rate on enzyme ALP. The initial experiment was done to approximate the optimum pH for the activity of the enzyme. The hypothesis was that alkaline phosphatase activity will be critically affected by pH effects. The hypothesis was valid because the data shows that the pH values for the acidic‚ basic‚ and neutral tubes increased over time‚ absorbing at similar rates. The basic

Questions Why do you think Janie only chooses to tell her story to Pheoby? I think that Janie decides to only tell Phoebe because she is her closest friend and sees her as someone she can trust she can trust her. Phoebe judges the women on the porch and is mad at the other girl for criticizing Janie. Therefore when she comes to Janie‚ you can tell by what she’s saying and her action (bring Janie a plate of food) that she is a real friend of hers. 2. If anything‚ what do you admire about Janie

Transformation of Bacterial Cells with Plasmid DNA Introduction: Transformation refers to the process in which the cell integrates foreign DNA to its genetic code‚ meaning it takes the genes and incorporates them into the cell’s current DNA. Cells that can do this naturally‚ most commonly bacteria and archea‚ are known as competent. The bacteria E. coli do not have high transformation competence under normal conditions‚ but can be manipulated to produce better results using
