Investigating the Effect of Temperature on Enzyme Activity Almost all chemical reactions that occur in living organisms are catalyzed by enzymes. Many factors in a cell’s environment affect the action of an enzyme. In this investigation‚ you will design an experiment to determine the effect of temperature on an enzyme-catalyzed reaction. You will complete an entire lab write-up using the CHS LAB REPORT FORMAT. Fundamental Question How does temperature affect the rate of an enzyme-catalyzed

The aim of this experiment was to determine the effect of caffeine on resting body temperature. This has to do with homeostasis‚ which is the maintenance of equilibrium. In other words‚ it is a stable body state. Homeostasis refers to the process of keeping the internal body environment in a steady state‚ when the external environment is changed (Homeostasis 2). Humans are warm-blooded creatures that generate body heat internally and maintain body temperatures at a fairly constant level – about

Effect of Catalase at Different Temperatures Abstract The role of this experiment is to determine the effect of temperature on enzymatic activity. The results of the experiment were the colder the temperature the slower the reaction rate and the hotter the temperature the faster the reaction rate. Introduction Enzymes are chemical substances found in living cells and they act as catalysts of the various chemical reactions that occur in them.(Preszler‚ 2012) They bind to substrates that have

Groyne Investigation FINAL Report‚ Alice Cearns ABSTRACT The purpose of the investigation is to analyse the effect a groyne has on a beach’s formation and sand deposition‚ and the seasonal impact the ocean has on its shoreline. South Cottesloe beach contains native plants‚ from berry saltbushes to red-eyed wattles; it has accumulated sea wrack and rocky surfaces especially south of the groyne‚ and sand dunes running down to the swash zone. With fences running parallel to the water line‚ this

phosphorylase in particular) are affected by varying its temperature before introducing it to the substrate it will be reacting with. A catalyst (enzyme) is a substance that changes the rate of a reaction; for a reaction to take place at all‚ the enzyme must first come into contact with the substrate. Enzymes are subject to a number of factors which effect how fast they can cause a reaction with a substrate; these factors include temperature‚ pH levels‚ chemical substances and the concentration of

move across the cell membrane is that the carbon dioxide molecules spread out rapidly out your red blood cells down their concentration gradient to your lungs. When water molecules move freely through your cell membrane is called osmosis as we learned last unit. The reason why molecules move across the cell membrane is because they are small molecules that have no charge like oxygen which the cell membrane need to survive. So basically the molecules that move across the cell membrane are necessary

INVESTIGATION INTO THE EFFECT OF TEMPERATURE ON CATALASE ACTIVITY AIM The aim of this experiment is to find out the effect of temperature on catalase or hydrogen peroxide. This will enable us to tell at what temperature hydrogen peroxide is most efficient. This (degradation) reaction will help us determine some of the catalase’s different attributes. HYPOTHESIS In this experiment it would be safe to hypothesise that no activity would take place at 1 to 20 degrees. It would be probable that a

The Effect of Temperature on the Enzyme Catalase Stephen Francis Biology 183 Abstract This experiment was performed to determine the resultant effect of temperature change on the reaction between the enzyme catalase and hydrogen peroxide. This experiment was performed by measuring and comparing the amount of oxygen bubbles produced and the absorbance of the catalase and hydrogen peroxide solution over time at room temperature‚ 2°C‚ 50°C‚ and 60°C. The overall result of this experiment proved

Temperature effects on the growth of microorganisms Introduction: The purpose of this experiment was to determine the effects that temperature has on three different organisms. Temperature is one of the most important environmental factors affecting growth and survival of microorganisms². The three organisms used where Escherichia coli‚ Pseudomonas fluorescens‚ and Bacillus stearothermophilis. Most bacteria grow within a particular temperature range. The minimum growth temperature is

investigated the effect of different temperatures on beetroot cell membranes (a type of plant cell). Through this experiment‚ the process of diffusion and osmosis was in action. Various temperatures ranging from low temperatures to high temperatures such as -5⁰C‚ 5⁰C‚ 30⁰C‚ 50⁰C and 80⁰C were used to investigate the temperature effects on beetroot cell membranes. The hypothesis predicted that the higher the temperature the darker the beetroot substance and the lower the temperature the least colour
