How does cellular respiration happen in animal cells?
- need oxygen to carry out this process
- cellar respiration
- blood cells in capillaries collect oxygen from air in alveoli
- diffuse out the blood cells into other body cells
- oxygen and sugar enter the cell and once in the cell enter mitochondria
- energy saved in ATP
- ATP is used to carry out the cellular process
- reaction between sugar and oxygen = carbon dioxide
- goes back to capillaries which re-oxygenate
