Cell Respiration Lab Research Question What is the optimal temperature for germinating pea-seeds where the rate of respiration is the greatest? Background Information Cell Respiration refers to the biochemical process conducted by the cells of an organism that combines glucose and oxygen to produce energy in the form of ATP, along with two by-products, water and carbon dioxide. The equation representing this chemical reaction is shown below. C6H12O6 + 6 O2 6 CO2 + 6 H2O + ATP Although plants and animals have different methods of obtaining glucose, the cell respiration process occurs in both types of organisms. Many external factors in the environment may affect the organism's’ rate of respiration such as the temperature of the surrounding, …show more content…

As the temperature exceeds this value, the rate of respiration will gradually decrease, reaching zero at a certain point. The optimal temperature for germinating pea seed is 20ºC because it is the average temperature of the Spring season in China, where it was first discovered. The trend for the rate of respiration is represented by the graph shown. During the cell respiration process, multiple enzymes are involved, therefore, the rate of reaction will be highest at a certain temperature, and will gradually decrease as the temperature gets further away from that particular …show more content…

As mentioned in the hypothesis, the prediction is that as the temperature increases towards the optimal, the rate of respiration will increase. As the temperature exceeds the optimal, the rate of respiration will decrease. The temperature of the environment can be varied by placing the respiration chamber under a temperature-controlled water bath/cooling bath. The temperatures that will be used in this experiment will range from 0ºC to 50ºC in 10ºC increments. Digital thermometer will be used to measure the temperature of air. Dependent Variable Rate of Respiration (Rate of which CO2 is produced in ppm/s) The rate of respiration of the germinating seeds can be represented by the rate of which CO2 is produced. The rate of respiration is expected to be affected by the change in temperature of the environment. As mentioned in the hypothesis, the change in the respiration rate is most likely to be due to the involvement of enzymes in the process. The rate of respiration of the germinating seeds can be measured by using the CO2 Gas Sensor. When connected to the data-collection interface, accurate rate of CO2 produced can be monitored. Controlled Variable Number of seeds Size of seeds Specie of

During this experiment, mitochondria were isolated from 20.2 grams of cauliflower using extraction buffer, filtration through Miracloth, and centrifusion. Twelve samples containing various volumes of mitochondrial suspension, assay buffer, DCIP, sodium azide, and citric acid cycle intermediates were prepared to be read by a spectrophotometer. The inclusion of the dye DCIP allowed for the absorbance of the reactions between the mitochondrial suspension and the TCA cycle intermediates succinate, malonate, and oxalate to be measured, as DCIP turns from blue to colorless as the activity of succinate dehydrogenase increases. Experimental Findings Increasing the number of mitochondria in the reaction did increase the reduction of DCIP relative to the amount of mitochondrial suspension present.

Compare And Contrast Cellular Respiration And Photosynthesis

420 Words | 2 Pages

photosynthesis and cellular respiration are extremely important in the cycle of energy to sustain life simply because nutrients would not metabolize in a productive manner. Both have numerous stages in which the process of energy occurs, and relationships with organelles located in the eukaryotic cell. Photosynthesis is a process by which green plant and other organism manufacture their food using sunlight to synthesize foods from carbon dioxide and water while cellular respiration is the oxidation of organic compounds that occurs within cells, producing energy for cellular processes. Photosynthesis occurs within organelles called chloroplasts. These organelles can absorb light, and are located inside of leaves.

Then, tests are performed to determine if the products of aerobic and anaerobic respiration are present in the flasks. The citric acid cycle consists of a series of chemical reactions used by all aerobic organisms to release stored energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins into carbon dioxide and chemical energy in the form of ATP (Biology). The tests detect the presence of carbon dioxide and ethanol. Carbon dioxide should be present irrespective of the type of respiration taking place, but ethanol is present only if fermentation has occurred. Another factor that can indicate whether fermentation occurred or cellular respiration occurred is the amount of glucose utilized during incubation.

This is very similar and related to the previously discussed objective of being able to identify biological processes that require energy. Modeling the way organisms capture and store free energy was achieved in several different labs, including the cellular respiration lab. In the lab, we modeled how an organism can capture and use energy through facilitating the germination of seeds. Germination is a very complex biological process that requires the capture and storage of energy for later use. Modeling this process allows further investigation and greater understanding of how energy is captured and used by

Cellular Respiration One of the main essentials of life that all organisms need in order to function in our world is, energy. We receive that energy from the food that we eat. Cellular respiration is the most efficient way for a cell to receive the energy stored in food. In cellular respiration, a catabolic pathway, which breaks down the molecules into smaller units, in order to produce adenosine triphosphate, also known as, ATP. ATP, is used by cells in the act of regular cellular operations, it is a “high energy” molecule.

The difference between 1.54% and 2.31% solute (sucrose) concentrations is very small, 0.63, compared to the difference between 0.00% to 1.54% solute (sucrose) concentrations. The mean height of the common wheat increases from 2.31% to 3.08% by 0.12.The mean height of the common wheat starts to decrease by 1.91 between 3.08% to 3.85% solute (sucrose) concentrations, getting closer to the decrease between 0.00% to 1.54% solute (sucrose) concentrations. The mean height of the common wheat tends to decrease steadily in the Graph 1.1 and it can be explained by osmosis. In the experiment there was concentrated (sucrose) solution added to the soil, which caused a low concentration outside the plant cell and made the water from the seeds (high concentration) to move to an area of lower concentration outside the plant cell. This made the common wheat seeds lose water, which is important in photosynthesis and growing, and therefore slowed down their
