Experiment 4 – Effect of Temperature on Enzyme Activity Aim To study the effects of temperature on the activity of amylase enzyme on starch solution. Introduction Enzymes are widely known as biological catalyst. Almost all cellular reactions are controlled and guarded by enzymes. Virtually every metabolic reaction which takes place within a living organisms are catalyzed by enzymes. Enzymes are complex three-dimensional globular proteins. Some of the enzymes are built up off proteins and

empty can and food items. 2. Fill can approximately one third full of water. 3. Weigh the can after water is in the can. 4. Take the temperature of the water in the can. 5. Place the first food item under the ring stand. 6. Set the food on fire then quickly place the can on the ring stand above the burning food. 7. Once the food has extinguished take the temperature of the water in the can. 8. Weigh the food that has been burned. 9. Pour out water that is in the can. 10. Repeat steps 2-9 for

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

all having their own drawbacks. But‚ the one that will be focused upon in this analysis is hydrogen as a source of fuel‚ and the technology leading the way to making it a reality. This technology would affect everyone in one way or another if correctly used. So we must ask if this technology is beneficial to us‚ how it might hurt us‚ and whether it is worth pursuing from an ethical stance. Background: Hydrogen has already been under the micro scope for many years as an alternative fuel source to us

This occurs because these forests are exposed to cold and warm air‚ which makes them encounter all four seasons. Temperatures in the deciduous are estimated to be up to 50°. They also have precipitation of 30 to 60 inches a year. One of the traits these trees have is thick bark that protects them from cold or really hot weather. Deciduous forests can be found everywhere

manage tourism in Epping forest. The purpose of this coursework is to find out about the impact which visitors have had on Epping Forest‚ and how the impact is being managed and reduced. Epping Forest has recreational‚ aesthetic and educational values‚ so is a perfect place for visitors(tourists) . I feel that considerable damage has probably been caused to the environment due to the large number of British tourists‚ and it is with this coursework‚ that I will try to find out whether the local government

As the temperature increased‚ the enzyme activity also increased‚ however‚ only to an optimal level which was at temperature 32oC. Once the temperature was beyond the optimal level‚ the rate began to decline and this was represented by the concave curve on figure 5 and 7. This was because as the temperature increases‚ the frequency of collisions between the enzyme and the substrate also increased hence faster reaction rate. Whereas‚ the enzymes operated slowly at low temperature as there wasn’t sufficient

For our media coursework we have been watching the film called Jaws‚ which was directed by Steven Spielberg. This film is set in 1970’s in Amity USA and is about a shark which attacks a lot of people. It is set on the 4th of July because that’s when Brody‚ the main characters‚ son was involved in one of the shark attacks. In the music sequence whenever the shark is near or attacking it has its own theme tune which is made to build tension because when you hear that music you know it’s the shark
