Effect of Heat on Respiration Rates

Introduction:

All living things require energy in carrying out activities. The process by which energy is made available from nutrient of cells is called cellular respiration. Cellular respiration is the controlled release of energy, in the form of ATP from organic compounds in cells.

Respiration occur under two conditions which is with the presence of oxygen and without the presence of oxygen. If there is presence of oxygen, then the process is called aerobic respiration. However, if there is lack or absence of oxygen, then it will refer as anaerobic respiration.

Respiration involves enzyme that can be affected by the temperature. The rate of the respiration increase with the increase in temperature until it reaches the optimum temperature. This is where the rate of the respiration is the highest. Further increase in temperature only lowered the activity of the enzyme as it begins to denature.

Research Question:

How does the temperature affect the rate of respiration?

Objective:

Investigate the effect of heat towards the rate of respiration of Mung beans.

Hypothesis:

The rate of respiration increases with the increase in temperature. This will continue until it reaches 60oC where the rate of respiration is the highest.

Drops

6 drops of Bromcresol is added using a dropper in the preparation of the indicator solution.

Bromcresol is used to detect the presence of carbon dioxide. With the increase of number of drops of bromcresol, the experiment will take more time for the reaction to occur. 6 drops of bromcresol ensures the experiment can be completed in the given time period.

Materials

 

Procedure:

a) Prepare the indicator solution

1. 50ml of tap water was added into a beaker, and then 6 drops of Bromocresol purple solution was added.
2. The colour of the solution changed to purple.

b) Prepare the standard solution

1. 10 ml of the indicator solution was transferred from the beaker into a test tube.
2. Expiring gas is blown into the solution using a straw. The solution changes colour from purple to greenish.
3. This was used as standard solution.

c) Conducting the experiment

1. The outer skin mung beans were peeled and the mung beans are put in a beaker. 100g of the beans is measured and put in a test tube.
2. 10 ml of the indicator solution was added into the test tube. The test tube containing mung beans is then put inside a water bath of 300C.
3. The temperature of the test tube is recorded and maintained using a thermometer.
4. Once in a while, the test tube was shaken and the time taken for the solution to change colour from purple to yellow as the standard solution was recorded using a digital stopwatch.
5. The experiment was repeated by changing the temperature (400C, 500C and 600C) respectively. It was controlled that the temperature of the mung beans and the solution while in the water bath reaches the temperature needed before adding both together.
6. The time taken for the colour to change for all different temperature is recorded suing a digital stopwatch.

Based on table 2.6, the graph of rate of respiration against temperature can be plotted.

Discussions:

Theoretically, the rate of respiration increase when the temperature increase until it reaches optimum temperature. At the optimum temperature, the rate of respiration is at the highest. After that, the rate of respiration will drop due to the denatured of the enzyme that involve in respiration.

But after the experiment is done, the results obtained shows that the rate of respiration keeps increasing till 60oC. We can say based on our experiment, the optimum temperature for the respiration of mung beans is more than 60oC.

The error is too small to be shown on the graph. This is because less error is being put in doing the experiment and safety precaution is taken.

The rate of respiration increases as the temperature increases until it reaches optimum temperature. Enzyme works efficiently at higher temperature because high energy is required for the enzyme undergoes the effective collision with the substrate frequently.

The Bromcresol solution function is to determine the existence of carbon dioxide gas in the air. If there is carbon dioxide gas, it will change colour from dark brown to yellow. So, time taken for the solution to change colour can be used up to measure the rate of respiration.

Limitations and suggestions

 

1. It is difficult to maintain the temperature of the test tube in 60°C as there is no electronic water bath is available.

Suggestion: The water for 60°C should be added so that it is easier for the students to maintain the experiment at 60°C rather than having their own water bath using Bunsen burner and beaker.

2. The exposure of the bromcresol solution to the surrounding may affect its reliability as an indicator. Some carbon dioxide gas from human respiration will affect the colour of the indicator.

Suggestion: The test tube that contains the bromcresol solution must be closed by using rubber stopper at all times.

3. The usage of distilled water in preparing the indicator solution is not suitable as the solution will be yellow when added with bromcresol.

Suggestion: Students should be aware of different situations of different solution and advised to use tap water in similar upcoming experiments

Conclusion

The rate of respiration increases with the increase in temperature. This will continue until it reaches 60oC where the rate of respiration is the highest. From this experiment, the optimum temperature of the respiration of the mung beans is 60oC. Hypothesis is accepted.
