They allow investigation into how factors such as age, chemicals or the effect of light affect the rate of respiration. Respirometers are designed to measure respiration either on the level of a whole animal (plant) or on the cellular level. These fields are covered by whole animal and cellular (or mitochondrial) respirometry, respectively.A simple whole plant respirometer designed to measure oxygen uptake or CO2 release consists of a sealed container with the living specimen together with a substance to absorb the carbon dioxide given off during respiration, such as soda lime pellets or cotton wads soaked with potassium hydroxide. The oxygen uptake is detected by manometry. Typically, a U-tube manometer is used, which directly shows the pressure difference between the container and the atmosphere. As an organism takes up O2, it generates a proportionate quantity of CO2 (see respiratory quotient), but all the CO2 is absorbed by the soda lime. Therefore all of the drop of pressure in the chamber can be attributed to the drop of O2 partial pressure in the container. The rate of change gives a direct and reasonably accurate reading for the organism's rate of respiration.As changes in temperature or pressure can also affect the displacement of the manometric fluid, a second respirometer identical to the first except with a dead specimen (or something with the same mass as the specimen in place of the organism) is sometimes set up. Subtracting the displacement of the second respirometer from the first allows for control of these factors.Respirometry, a general field of study referring to the study of metabolic rates in various organisms, can include the use of a respirometer. In a respirometry lab, researchers have access to a number of pieces of equipment which can be used to study metabolic rates and various metabolic processes. Understanding how metabolism functions in healthy organisms can be important, especially when people start exploring metabolic errors and their causes. Most such equipment comes with detailed guides which show how it should be used and maintained for safety and data validity.
|Information||A respirometer is a device which is used to measure respiration, where organisms exchange carbon dioxide and oxygen as part of their metabolism. These devices can be used to study plants and animals alike to learn more about their respiratory patterns, and to monitor the health of an individual organism, using known information about that organism as a baseline. Respirometers are sold by a number of scientific supply companies, and they are also improvised in lab environments, since the mechanics are relatively straightforward.Using a respirometer to obtain baseline measurements, researchers can see how changes in environmental or genetic factors can impact respiration. For example, the environment can be heated or chilled to see if this causes changes, or people can study the impact of various air mixtures which can mimic air at high altitudes, air at low altitudes, or air in certain environments. With organisms like fruit flies, genetic research can include the use of respirometers to collect data on genetically modified organisms.These devices must be carefully monitored during use to avoid creating a dangerous situation inside the respirometer. If the space becomes filled with metabolic wastes, the organism may not be able to breathe, and conversely, if the organism uses up substances such as oxygen, it will be in danger. Tight controls of the environment ensure that people know exactly what the organism has taken up and put out while inside the respirometer.|
