Cellular respiration experiment with beans Rating:
Cellular respiration is the process by which cells convert the energy stored in glucose into a form that can be used by the body. One way to investigate cellular respiration is to conduct an experiment using beans.
To begin the experiment, you will need the following materials:
A package of dry beans (such as kidney beans, pinto beans, or black beans)
A sealable plastic bag
A watch or timer
A balance or scale
First, measure out 50 grams of dry beans and place them in the plastic bag. Next, seal the bag tightly and place it in a warm, dry location. Allow the beans to sit for 24 hours.
After 24 hours, weigh the beans again to determine their mass. Record the mass in a data table. Then, place the beans in a pot of water and bring the water to a boil. Boil the beans for 10 minutes, then drain the water and allow the beans to cool.
Once the beans are cool, weigh them again and record the mass in the data table. Calculate the difference between the initial mass of the beans and their mass after boiling by subtracting the initial mass from the final mass. This difference represents the water weight that was lost during the boiling process.
To calculate the amount of glucose produced during the process of cellular respiration, you will need to use the following formula:
Glucose (g) = Water weight loss (g) / 0.6
The value 0.6 is a conversion factor that takes into account the fact that each gram of glucose produces 0.6 grams of water during cellular respiration.
Using the value you calculated for the water weight loss and the formula above, determine the amount of glucose produced by the beans during the experiment. Record this value in the data table.
You can repeat the experiment using different types of beans to see if there are any differences in the amount of glucose produced. You can also try varying the length of time the beans are boiled to see if this has an effect on the amount of glucose produced.
Overall, conducting an experiment on cellular respiration using beans can be a useful and interesting way to learn about this important biological process. By measuring the mass of the beans before and after boiling and using a simple formula, you can determine the amount of glucose produced during the process of cellular respiration. This can help you understand how cells convert energy and how different factors can affect this process.

ATP can be recycled by sticking the phosphate back on again. The vial with only beads, the equilibrium period of 8 minutes, and the same volume in all vials are all constant controls in thisexperiment. The germinated mung beans were increased in size from the ungerminated mung beans and were a brighter green colour. While equal does contain dextrose that the yeast can break down it also contains chemical bonds that the enzymes of yeast cannot break down. It is important to have a control because it shows the different outcomes each beaker had.
How do the results of this experiment relate to the role yeast plays in baking? The glass beads served as the control for the experiment as they did not perform cellular respiration. If the respiration in small mammals was studied at room temperature, then I would predict that the mammal at the temperature of 21 degrees Celsius would go through the most cellular respiration. Using the same experimental design, write a hypothesis to test the respiration rateof a 15 g reptile and a 15 g mammal at 10° C. The ones with no beans remained the blue-green tint. This process results in the production of oxygen, water, and glucose sugar. Takereadings of the volume of water in each pipet every 5 minutes for 20minutes.
This also supported my hypothesis that the crickets would have a higher rate of oxygen consumption than the worms. Insert the cork assembly into the vial tightly. You may need some plastic wrap if you run out of parafilm. Put non-absorbent cotton balls in each respirometer above the KOH pellets and then add the peas and beads. This activity uses a number of controls. Cellular respiration must have occurred with the beans because the solution changed color. Despite instances of systemic and human error, the results demonstrated a successfully constructed experiment.

Conclusion: I can conclude that my hypothesis is correct because the data tables and graphs show that if the temperatures are colder, then less oxygen will be consumed meaning that the rate of cellular respiration would be low. I used the data provided by our teacher, Mrs. I would then do the tube trick to mix it together. The reason cold water causes the rate of respiration to decrease is the metabolism slows down and therefore doesn't require as much oxygen. Kinds of sugars iii. If the 15 g mammal and 15 g reptile both maintain homeostasis and have no differences in the amount of energy used, then the mammal would have a higher respiration rate than the reptile.
Possible errors that could have skewed our results would be: Using the incorrect amount of beads, not calculating the corrected difference of the values correctly, and also having water fill up the vials during the experiment. Throughout hydrolysis, in order to make the reaction occurred, it had to get through a threshold, known as the activation energy. The non-germinated beans and beads will be used in respirometer B. The glucose and sucrose will have a high respiration rate because it has more additives in it. We were also able to see how cellular respiration of germinating peas differs from non-germinating peas. Another error due to time constraints is that with the worm and cricket experiment we were not able to monitor it for the full 30 minutes, and instead only monitored it for 12 minutes.
Cellular respiration creates ATP. How do the results of this experiment relate to the role yeast plays in baking? The color changes from blue to green and green to yellow in the beaker with germinating beans, in the beakers with no beans and unsoaked beans it remains blue. Place them with the calibrated side of the pipet facing up to allow measurements to be taken. Repeat this process with the second set of germinating beans for Vial D. It showed where cellular respiration was present. We can infer that there is acid present in the beaker containing soaked beans, this is due to the release of co2 during cellular respiration.

In this experiment, we could put germinating peas, non-germinating peas and beads, and glass beads in vials for the first experiment and a worm, cricket, and glass beads in the vials for the second experiment. Why are the readings corrected using the glass bead values? Indicate sources of error and suggest improvements for example, what types of controls could be added? While their rates of oxygen consumption were close, the germinating seeds had a greater rate. Place a small absorbent cotton ball in each of the six vials and push each down to the bottom using a pipet or pencil tip BE SURE to use the absorbent cotton balls and NOT the non-absorbent rayon 9. During cellular respiration, the oxygen is used to transport the pyruvate into the mitochondria through the matrix so it can undergo the Krebs Cycle. What will be your dependent variable? This can explain why at 10°C there is little cellular respiration and at 40°C there are high levels of cellular respiration.
There is a possibility of observing the pipets incorrectly or writing the measurements incorrectly. Record thetemperature of the room temperaturebath. Insert the cork assembly into the vial tightly. What are 2 control variables you would use? For respiration, the plant needs some of its sugar, plus oxygen and water. Energy is released when the P pops off. The leftover glucose is packaged into starches or fats and is stored in The roots, seeds and fruits. Explain the results shown in the sample graph in your lab manual.
