Thus, if respiration proceeds in a closed system the volume of gas will remain constant even though the composition of the gas changes, If the liberated carbon dioxide is removed then the volume of gas in a closed system will decrease. The amount of the decrease with time will reflect the amount of carbon dioxide liberated as well as the amount of oxygen used during respiration. Keeping this information in mind. Each respirometers consists of a test tube with the test material , pellets of KOH suspended above the material on glass wool, a set of tubes which join the test tube to a u-tube with fluid and a 1 cc syringe. This is referred to as poikilothermic or ectothermic .
Humans are one of a large group of animals which are termed homeothermic or endothermic .
Name the specific parts of the cells where the various steps of catabolism takes place. If you oxidize glucose with a flame in a bowl, a large amount of heat is given off.
