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

Concentration on Peroxidase ABSTRACT The purpose of this experiment was to inspect the effect of environmental conditions on hydrogen peroxidase. The three conditions tested were the effect of peroxidase concentration on the rate of the experiment‚ the effect of pH of the rate of peroxidase activity‚ and the effect of temperature on the rate of peroxidase activity. During the lab‚ the lab group tested 7 test tubes‚ including 1 blank‚ with different amounts of pH 5 buffer‚ H2O2‚ Peroxidase‚ and Guaiacol.

Enzyme Lab Introduction/ Abstract An enzyme is a substance produced by a living organism that acts as a catalyst to bring about a specific biochemical reaction. They are mainly made up of proteins and can tremendously speed up reactions. E. coli ( a bacterium) has about 1‚000 different types of enzymes floating around in its cytoplasm at any given time. Enzymes can be used to join and even break up molecules as shown in the diagram below. (1)

Hydrogen Fuel Cell Cars: Worth the Investment? Hydrogen is the most abundant element in the universe‚ but only recently have people been able to harness this resource and turn it into energy. Hydrogen fuel cell cars are one such advancement made in the effort to turn hydrogen gas into electricity. Fuel cells in the car are used to convert hydrogen into an electrical current‚ and thus power the vehicle. Fuel cells convert hydrogen and oxygen into water while producing electricity. Hydrogen fuel

Factors Affecting Enzyme Activity Abstract: In the following lab factors affecting enzyme activity‚ temperature‚ pH‚ enzyme concentration‚ substrate concentration and surface area will be tested on a beef liver enzyme to see if there will be any effect of performance. By doing 2 or more trials the results will show whether there is an effect to the enzyme from the following factors or not. Some of the factors may denature the enzyme and some will do nothing. Using a table qualitative and the

Discuss why hydrogen bonding is essential for life Throughout biochemistry there are many bonds without which life as it is on earth today would not be possible. One of the most important bonds of these is the hydrogen bond‚ a weak chemical bond that is present in essential biological molecules such as water and polypeptides. A hydrogen bond is defined by Campbell and Reece as occurring when a hydrogen atom is covalently bonded to an electronegative atom but attracted to another electronegative

Chapter 14 - Kinetics of a Particle : Work and Energy In this chapter‚ students will get to learn about the concepts of involving work and energy including the work of a force that acts on particles. Therefore‚ students can develop the principle of work and energy and the concepts of a conservative force as this equation can be useful for solving problems involving force‚ velocity and displacement and also can solve the kinetic problems. So in general‚ this chapter will enable students to analyse

Experiment 8 Chemical Kinetics Abstract This experiment was done to determine the effects of the nature of the reactants‚ concentration‚ temperature‚ surface area and catalyst on the rate of chemical reactions. The nature of the reactants implies a difference if the reactants are aqueous or organic‚ acidic or basic or if they occur in the same phase or not. Acid-base reactions‚ formation of salts‚ and exchange of ions are fast reactions while reactions in which large molecules are formed

In this lab‚ I was testing different temperatures and how it 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
