How does respiration occur outside of cells?
Cellular Respiration is a kind of respiration. It is needed to take place in order to provide energy for the cells in the body of a living organism. Cellular respiration takes place in the cells of a living organism. It converts nutrients to energy, releasing some as waste when it is no longer needed.
Respiration is always cellular. There is no respiration outside the cells.
Either in animals or plats the respiration is anaerobic and aerobic,
Anaerobic respiration is in cytoplasm of all cells. It is without external oxygen. Example is glycolysis.
Aerobic respiration is outside the cytoplasm in mitochondria. The end product of glycolysis enters in mitochondria.
Both anaerobic and aerobic respiration generates energy in terms of ATP
