A Max Plank respiration gas meter is a small, compact, and lightweight backpack-mounted respirometer (Fig. 4). It combines a gas volume meter and a sampling device for continuous sampling of each breath of expired air. The Max Plank respirometer consists of a dry, bellow-type gas meter for measuring the total volume of expired air during activity. Respirometry. Respirometry refers to a group of techniques where a quantitative measurement of respiration is performed. It is based on an indirect measurement of metabolic changes by recording variations in oxygen levels in a respirometer due to energy consumption of an experimental animal model. Method. Measure oxygen consumption: set up the respirometer and run the experiment with both tubes in a controlled temperature water bath.Use the manometer reading to calculate the change in gas volume within a given time, x cm 3 min-1 Reset the apparatus: Allow air to reenter the tubes via the screw cap and reset the manometer fluid using the syringe. Cellular respiration is the process by which cells in living organisms break down glucose and other nutrients to produce energy in the form of adenosine triphosphate (ATP). This vital biochemical pathway fuels various cellular activities essential for life. During cellular respiration, glucose is oxidized through a series of metabolic reactions Applications. Respirometers are used to monitor both aerobic and anaerobic processes. A respirometer may be used to monitor the biodegradation reactions that take place during the microbial breakdown of hydrocarbons or plastics. For example, specific microbes are used to clean up oil spills. A respirometer designed to measure the level of Measuring Respiration with a Respirometer - learn-biology. Measuring Respiration with a Respirometer. This video explains some of the science behind this demonstration of oxygen consumption during cellular respiration.
