A description of the use of the respirometer to measure oxygen consumption by respiring organisms. the focus is on setting up the experiment rather than on t. 1 scientific questions and information research. before you start the experiment you should: research relevant information about the design and use of respirometers. look at the respirometer in figure 1. annotate the diagram to show what each component does or make a list of the components shown for this respirometer and suggest their functions.

A respirometer is a device used to measure the rate of carbon dioxide production in respiration, as an indicator of metabolic rate. it consists of a chamber that contains the organism or tissue, a manometer to measure pressure changes, and an absorber of carbon dioxide. as organisms respire, they use up oxygen and produce carbon dioxide. Edexcel a biology a levelcore practical 16. nvestigate rate of respiration practically.a respirometer is a piece of equip. ent which measures the rate of respiration. it works by the addition of a dr. p of coloured liquid to a length of tubing. as the organism respires and the volume of oxygen in the tube decreases, the pressure also decreases.
