What is external respiration and internal respiration?
External respiration is to breathe and facilitate gas exchange in the lungs or an analogous body cavity, depending on the organisms anatomy. Cellular respiration is the process of oxidative phosphorylation, where ATP energy is generated from biomolecules by the cell. In aerobes, the process involves a series of electron steps and oxygen is the terminal electron acceptor
Where does the external respiration process take place?
External respiration occurs in the lungs where oxygen diffuses into the blood and carbon dioxide diffuses into the alveolar air. Internal respiration occurs in the metabolizing tissues, where oxygen diffuses out of the blood and carbon dioxide diffuses out of the cells.
