LAB 9: DATE: 25TH January‚ 2011. FORM CLASS: L6 3 SUBJECT: Biology TITLE: Enzymes AIM: To investigate the effect of temperature on the enzyme lipase INTRODUCTION: The phenomenon of catalysis makes possible biochemical reactions necessary for all life processes. Catalysis is defined as the acceleration of a chemical reaction by some substance which itself undergoes no permanent chemical change. The catalysts of biochemical reactions are enzymes and are responsible for bringing about almost

The activity of an Enzyme is affected by its environmental conditions and changing these factors can alter the overall rate of the reaction. Reaction rates are influenced by external factors such as pH‚ temperature and salt concentration. Different enzymes have different optimum temperatures in which they are most efficient and different pH levels which is ideal for their formation of enzyme-substrate complexes. As the temperature increases‚ there is more movement of molecules and more random collisions

Conclusion…………………………………………………………………………....…….8 Works Cited ………………………………………………………………………………..9 Properties of Enzymes and Competitive Inhibitors. Abstract: Properties of enzymes were found in this experiment and some other factors‚ which affect enzyme activity. Enzymes are catalyst; they catalyze very specific reactions. Results relating to the active site of specific enzymes played a big role while performing this experiment. The purpose of this experiment was to fin how inhibitors affect

Matthew Saldanha Bio DCP lab-Catalase experiment Aim: To investigate enzyme kinetics‚ using different concentration of the enzyme. Hypothesis: The assay system used in the lab consists of a filter paper disc coated with the enzyme and the dropped into a papercup of substrate (Hydrogen Peroxide). As the hydrogen breaks down the hydrogen peroxide into hydrogen and oxygen gas‚ the bubbles of oxygen gas collect underneath the filter and make it

Intrinsically they have like outcomes on the human body to anabolic steroids‚ triggering fast weight and force advances‚ but of a minor scale cause of the frequency limiting consequence produced by the enzyme adaptation. However‚ this theoretical explanation is thought-out somewhat outdated due to the expansions which have been done in supplement science. Epistane is amongst the hottest upscale steroids obtainable today‚ and it is achieving attention very

Catalysts in Fahrenheit 451 by Ray Bradbury Deandra Way Mr. Lacroix ENG3U 10/31/14 Saint Theresa Catholic Secondary School In Fahrenheit 451 by Ray Bradbury‚ there are three characters who act as catalysts in Montag’s life. A catalyst is person or thing that precipitates an event or change (Google). Clarisse initiates the earliest changes in Montag’s character as she subtly forces him to develop his self-awareness. With this self-awareness‚ Montag is inspired and encouraged by Professor

Biomes Comparison Essay Ecologists group earth’s diverse environments into biomes. A biome is a complex of terrestrial communities that develops a large area and is characterized by certain soil climate conditions and particular assemblages of plants and animals. Not all species live in every biome they vary in their adaptations to different conditions. An adaptation is an inherited characteristic that increases an organism’s ability to survive and reproduce. These sorts of variations in plants
