Aim:

Therefore the aim of this experiment is to investigate the effect of increasing temperature on the activity of the enzyme catalyst.

Hypthesis:

The froth volume increases as temperature goes up until an optimum point of around about 40C and after that point the enzyme is denatured and the graph starts to decline. Experimental Procedures

Variables

The independent variable that is changed and controlled specifically to test the effect of the independent variable on the dependent variable is the temperature of the hydrogen peroxide and the liver, which affects the froth volume, which is the dependent variable.

The volume of the froth kept rising until it was at its peak at 30 degrees and then the volume started decreasing. Hence the optimum temperature according to the results was 30 degrees with a volume of 62 ml.

The graph also has an optimum temperature of 30 degrees however the froth volume was 47.0.

Both figure 2 and 3 display a quadratic and have an optimum point. The graphs have the same nature as one another. The gradient of both graphs are positive then negative. However the values on both graph differ.

The volume of the froth at 10 degrees for the single data was 30 ml, while the volume for the average date at 10 degrees was 35.2 ml. The volume for froth at 20 degrees for the single data was 42 ml, while the volume for the average data was 40.5 ml. At 30 degrees the volume of the single data was 62 ml and the average data was 47.0 ml. At 40 degrees the single data had a froth volume of 35ml and the average data had a volume of 45.0ml. Finally at 50 degrees the volume of the froth for the single data was 32 ml and the average data was

## Purpose Of Homeostasis

1302 Words | 6 PagesAfter a meal, the digestion of the carbohydrates and sugars in the food releases glucose into the bloodstream. As blood glucose levels begin to rise above the set point of 5mM, the beta cells of the pancreas secrete the hormone insulin (1). The hormone sends a message to the liver that the levels of blood glucose have been detected to be too high. The liver begins the process of glycogenesis, converting glucose into glycogen. Glycogen is then stored in the liver, lowering the blood glucose levels.

## Enzyme Turnip Peroxidase Lab Report

1117 Words | 5 PagesThe three things that can cause the enzyme to denature is a large change in pH level, High Temperature, and substrate concentration. According to our knowledge, we know that a large change in pH will cause instability in the protein structure thus resulting in denaturation of the enzyme. From the data, we can see that pH 3 (total:6.3) and 10 (total:6.2) were the slowest because pH 3 is probably the highest acid and pH 10 is the highest base. The highest acid or base pH represents a large change which would cause the enzyme to denature. The fastest pH was 6 (total:34.5), and it seems that there wasn’t a large change which resulted in a stable structure.

## Supreme Laryngeal Mask Case Study

2516 Words | 11 PagesIn our study, though the median volume of air used for cuff inflation was 20 ml for size 3 SLMA and 30 ml for size 4, the volume ranged from 15-30 ml for size 3 and 20-30 ml for size 4 which is much higher than that recommended. This could possibly be explained by the fact that in 24 patients, a one size smaller SLMA was used. In 16 patients who weighed >70 Kg a size 4 SLMA was used instead of a size 5 which is not easily available. The cuff was therefore probably overinflated to minimize a leak. A study by C.Verghese and B.Ramaswamy 9 showed median volume of air for cuff inflation to 60 cm H₂O was 21.9

Formulation P1 exhibited the least buoyancy lag time (26 s) while formulation P6 exhibited the highest lag time (219 s). The decrease in the buoyancy lag time of a formulation P1 can be attributed to the availability of an increased amount of carbon dioxide as the with concentration of calcium carbonate which was entrapped in the formed gel to give rapid buoyancy. Irrespective of formulation variables, buoyancy duration was >12

## Enzyme Experiment: The Temperature Of The Enzyme Experiment

876 Words | 4 PagesThese are examples that can decomposition of the hydrogen peroxide. The temperature of the liver The surface area of the liver The Ph. of the hydrogen peroxide The concentration of the enzymes The variables I am going to look at are, different Temperatures in hot water baths, and one with an ice bath. My Hypothesis for this experiment would be that the temperature of the liver enzymes would react best at, 35-40 degrees, because the enzyme in the liver wouldn’t exist after 40 degrees Celsius I know this because of this is the experiment that I have just carried out, as soon as the rate goes over every ten degrees Celsius the liver is warmed up but when it goes over 40 Celsius the rate of decomposition will slow it down, So reaching the highest Celsius in my experiment would be 60 Celsius so therefore the enzyme really wouldn’t exist. There for my enzyme activity would be at its greatest in room temperature.

## Fepo4 Lab Report

932 Words | 4 PagesParagraph 1 The research paper talks about how the temperature of formation and crystallinity of iron phosphate, FePO4, is critical in determining its electrochemical behaviour. FePO4 is known to crystalline in several different structures. At 600 degrees, FePO4 irreversibly changes into an electrochemically inactive quartz-like structure, which shows that the olivine form is metastable. FePO4 at a high temperature is limited to measurements of call parameters. In the case of α-phase FePO4, cell parameters tend to increase exponentially as temperature increase.

## Tension Test Lab Report

1182 Words | 5 PagesTable 1: 2024T351 Specimen Experimental Data The experimental ultimate tensile strength of 65,507.15 Psi is relatively close to the typical tensile strength of 64,000 Psi with 2.35 percent error. The experimental young's modulus of 10,644,380 Psi is close to the standard elastic modulus of 10,600,000 Psi with 0.42 percent error. Using the graphs, the yield stress was found using a 0.2% offset. The yield stress was found to be about 50,000 Psi, far from the standard 42,000 Psi. This resulted in a 19.05 percent error.

Then the scientist will observe the different rates of reaction with temperature. The Boltzmann distribution of law, indicates that high temperature makes molecules gain high energy contents (pubs.acs.org/doi/abs/10.1021/ja). In order to measure the reaction rate, the scientists must use the same volume of water at three different starting temperatures: hot tap

## Catalase Enzyme Lab

1511 Words | 7 PagesThe beginning reaction that occurred at the pH level of 1 shows that the mean reaction rate was incredibly low, at 2 mL/minute. This then increased by 57 units once it reached its peak productivity of 59 mL/minute observed at pH 8. pH levels 6, 7, and 8 only varied between 1 and 2 mL/minute, which demonstrated similar rates of reaction. At pH 10, the reaction rate decreased considerably as it declined by 58 mL/minute, and maintained that productivity at pH 12. The scatter graph included in the results section further solidify and visually represent these observations. The reaction rate of the catalase exposed to pH 1 is barely conceivable on the diagram as its average rate of reaction was 2 mL/minute.
