activity using hydrogen peroxide. Hypothesis: My hypothesis for this experiment is that temperatures near body temperature is when enzyme activity will be at its highest. I believe this will occur because in our body‚ enzymes are very efficient. I also think that as the temperature of the water increases‚ there will be more enzyme activity. Materials: 1. Water/Ice 2.

reactions. (Evert‚ RF & Eichhorn‚ SE 2013). Enzymes also control plant metabolic processes such as respiration (Evert RF‚ Eichhorn SE & Perry JB 2013). This experiment focuses on the enzyme catalase. Catalase breaks down hydrogen peroxide into water and oxygen. Hydrogen peroxide is a waste product of cell metabolism that can be toxic to the cell (Evert RF‚ Eichhorn SE & Perry JB 2013). The

serves as a biological catalyst (Denniston‚ 2007). Metabolic reactions happen with in cells. Enzymes are proteins that are used to speed up these reactions without being consumed by them (Mader‚ 2010). Catalase is a catalyst that digests potent hydrogen peroxide and converts it into H2O and O (Campbell Reese‚ 2008). The environment plays an important role in the reaction that enzymes have. In this experiment‚ enzymes were exposed to changes in temperature‚ pH‚ and concentration. Introduction

can be found in everyday products. For example‚ the light omitted by fireflies‚ deep sea fish and glow sticks is a result of this process. Luminol was synthesized from from 3-nitrophthalic acid and then combined with potassium ferricyanide and hydrogen peroxide to omit a blue light. The product of this reaction is very unstable and is made by losing a nitrogen and the electrons go from an excited state to ground state and energy emitting as a photon creating the blue light.

Graduated cylinder Hydrogen peroxide Procedure: 1. Place all 5 glass tubes face up in the drying rack 2. Use tweezers and soak one potato cube into water and leave it there for 2 minutes. 3. After 2 minutes‚ use tweezers and place the potato into the first testing tube. 4. Repeat steps 2 and 3 four more times except soaking the other 4 potatoes in baking soda solution‚ bleach‚ vinegar‚ and lemon juice. Place the potatoes in each tube respectively. 5. Pour hydrogen peroxide into the 50 ml glass

Purpose: In this experiment‚ the purpose was to have found out how different chemical solutions help or harm radish plant growth when the seeds of the radish plant are soaked in said solutions prior to planting. Background: The IRP project I am doing is based off the subject of seed germination. The seeds I will be planting are cherry belle radish seeds‚ freshly bought. Instead of planting the seeds in soil like it is normally done‚ the plant seeds will be placed on paper towels to grow for better

Title: Enzyme Activity Lab Purpose: To measure the rate of enzyme activity from a tissue abstract and experiment with different factors‚ such as the enzyme solution and the substrate with different hydrogen peroxide percentages and temperature‚ that affect enzyme activity. Hypothesis: 1) If the disk is placed into each beaker with 100 units/ml of enzyme solution‚ then the time for the disk to float will be 30 seconds. 2) If the temperature of the solution is at 5 degrees Celsius‚

The decrease in wound size (cm) were measured daily for a period of 10 days and the data gathered were subjected to statistical analysis. At the end of the 10-day experiment period‚ T3 (Plain Normal Saline Solution) promoted the fastest decrease in wound size (cm) followed by T1 (Hydrogen Peroxide)‚ T2 (Betadine)
