    Frozen Tears: Psychodrama in the Resolution of Trauma and Grief By Tian Dayton PhD‚ TEP “The deepest pain has no words‚” echoes the ancient Chinese proverb. Today’s trauma theorists‚ it would seem‚ agree. Time stands still and so do we when something frightening is happening that doesn’t fit into our framework for “normal.” We freeze like a deer in the headlights- locked in a trauma response that was coded into us from the beginning of survival‚ from the earliest development of the human brain

    Catalase Lab Purpose: To observe the effects of hydrogen peroxide on living tissue and non-living materials‚ showing the presence or absence of catalase as observed by the presences of bubbles. Hypothesis: If we pour H2O2 on certain substances‚ the catalase will break down and bubbles will appear at the surface. Data table: Name | Time | Observation | Raw Potato | 1 min. 30 sec. | Slow reaction‚ barley any bubbles. | Raw Liver | 5 min. 30 sec. | Extremely fast reaction‚ very foamy‚ Big

    Abstract The aim of this study was to test the rate of reactivity of the enzyme catalase on hydrogen peroxide while subject to different concentrations of an inhibitor. The hypothesis was that hydrogen peroxide will be broken down by catalase into hydrogen and oxygen‚ where a higher concentration of inhibitor will yield less oxygen‚ resultant of a lower rate of reaction. Crushed potato samples of equal weight were placed in hydrogen peroxide solutions of various temperatures. The results showed

    temperature on the reaction between Catalase and H2O2 Sarah AlShemesi In this experiment we’ll be exploring the effects of temperature on the reaction between Catalase and H2O2.We’ll be using five different temperatures to test this. The five different temperatures will be 10‚ 30‚ 50‚ 70 and 90 oC. We will use the liver as a source of Catalase. A 1 gram piece of liver will be inserted into a test tube with 2 cm3 of water‚ then 2 cm3 of H2O2 will be added. The Catalase and H2O2 are expected to react

    enzyme; this is where the magic happens. Substrate is what is being broken apart by the enzyme. In this case‚ the enzyme is catalase and the substrate is hydrogen peroxide‚ or 2H2O2. As the catalase and the substrate interact‚ the substrate is brought into the catalase and broken apart into water and oxygen. This process may be able to happen naturally‚ but the enzyme‚ catalase‚ speeds up the process.

    graph shows that the highest rate of reaction is at pH 7. This therefore supports my theory that at pH 7 the rate of reaction will be highest. This relate to other resources‚ such as books and the internet‚ which show that the optimum pH value for catalase is pH7‚ therefore there is no difference between the optimum pH and the pH used in the experiment‚ hence the enzyme structure is not affected by the pH and is most active. However the graph inadequately supports the second part of the prediction

    The results provide evidence that when there was an increase in the sodium chloride concentration the mass of the potato prisms declined. At the zero percent concentration there was an increase of mass by 1.75%‚ from there the 1%‚ 3%‚ 5% and 10% begun on a downward trend with the percentage change in mass declining. The graph was on a steady decline from 0% being the highest point with a change of mass of 1.75% finishing with the 10% solution on a decline of -12.28%. From observing the scatter plot

    affects the time 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
