There are two types of 'respiration': pulmonary (visible breathing) and cellular (which is not visible). In pulmonary respiration the unwanted gas expelled is mainly carbon dioxide. This is then replaced during the inhalation breathing phase by the oxygen content in the air.
Cellular Respiration. Cellular respiration is a type of metabolism in living organisms that releases energy in the cell. These reactions are said to be catabolic, which means they are a set of pathways that require larger molecules to be broken down into smaller molecular units so ATP can be produced.
