Production of co2 (how many moles of co2 are produced in cellular respiration ) and the release of energy during cellular respiration in this lab, the volume of o2 consumed by germinating and non-germinating peas at two different temperatures will be measured pv=nrt is the inert gas law p is the pressure of the gas. In this activity, you are investigating both the effect of germination versus non- germination and warm temperature versus cold temperature on respiration rate germinating peas should consume more oxygen than non-germinating peas peas germinating at warm temperatures should consume more oxygen than peas. The ap biology lab 5 uses respirometry techniques to calculate the rate of oxygen consumption (cellular respiration) in germinating pea seeds the effect of temperature and whether a seed has broken dormancy are quantified and graphed the ideal gas law and its concepts are reviewed and applied.
From the respiration figure it is possible to see that during cellular respiration oxygen is used while carbon dioxide is being produced this relationship we will make use of this information to measure the overall rate of respiration in plant material (germinating seeds) and animal material (flour beetle larvae) keeping this. Study the effects of diffusion through a semipermeable membrane quantify oxygen consumption rates in germinating peas under different conditions predict the effect of temperature and germination state on the rate of cell respiration background each individual cell is responsible for the energy exchanges necessary.
In the cell respiration laboratory kit for classic ap biology lab 5, study the amount of oxygen consumed by seeds and the effect of a cold environment on plant growth: how paul andersen explains how a respirometer can be used to measure the respiration rate in peas, germinating peas and read this essay on. Pea and bean seeds may even begin germinating during the experiment main concepts all cells (plants and animals) perform cellular respiration to maintain homeostasis and grow the unique dormancy and germination cues of a seed are adaptations for a seasonal or variable environment experiments can produce. I think this because the mammal is warm blooded, and just like the germinating peas in the warmer temperature, the oxygen consumption was higher in warmer the water moved into the respirometer's pipettes because during the cellular respiration process, the oxygen is consumed and the carbon dioxide is produced. A respirometer is a device used to measure the rate of respiration of a living organism by measuring its rate of exchange of oxygen and/or carbon dioxide m) carry out investigations, using simple respirometers, to measure the effect of temperature on the respiration rate of germinating seeds or small.
Mr andersen walks you through the cellular respiration lab intro music atribution title: i4dsong_loop_mainwav artist: cosmicd link to sound:. Cellular respiration is the process by which all eukaryotic organisms--organisms with complex cells--produce usable cellular energy from food and oxygen peas are seeds that begin respiring when they germinate, and temperature can have an impact on the rate of pea respirationthe ideal temperature.
