    Effect of Temperature on Enzymes ~Abstract~ In this experiment the effect of different types of temperatures on enzyme activity was examined. The temperature baths that were used to test the difference in enzyme activity on fresh liver were; 4 °C‚ room temperature which was 22°C‚ body temperature which is 37°C‚ and 77°C. The total time of each trial was 2 and a half minute‚ 1 minute for the H2O2 to acclimatize to the temperature‚ 1 and a half minutes for the reaction to occur. Catalase causes Hydrogen

    apple juice. Since I am only varying the concentration of the enzyme (pectinase) I will have to make sure that all other variables are maintained (e.g. Temperature‚ PH and the amount of apple pulp). This is because enzymes are affected by temperature‚ pH and concentration. Equipment | Why I am using this equipment | Apple pulp | I am using apple pulp as an example of a fruit to determine the maximum amount

    Research Question Does the concentration of substrate (H2O2 (hydrogen peroxide)) have an effect on the activity of the enzyme (catalase)? Theory The higher the substrate concentration the more quickly product is produced (rate of reaction increases) until enzyme saturation is reached at which time more substrate has no further effect. Enzymes such as Catalase are protein molecules which are found in living cells. They are used to speed up specific reactions in the cells. They are all

    ISA CONTROLLED ASSESSMENT- Thermistors SECTION 2 ( Part 1 ) Answers 1. Yes the results support my hypothesis‚ which was‚ as the temperature increases the resistances decreases. For example the resistance at 20OC was ______ and at 50OC it was ______ which was much lower. Also the graph shows a negative correlation with a curve of best fit. This shows the relationship is not Ohmic as it is not a straight line. 2. EITHER; Yes I had an anomalous result‚ it was at a temperature of __OC. It was higher/lower

    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 98.6oF (Chiras 3). In this
