Summary:
- Cellular respiration is the process of extracting energy in the form of ATP from the glucose in the food you eat.
- Oxygen and glucose are both reactants of cellular respiration.
- When one molecule of glucose is broken down, it can be converted to a net total of 36 or 38 molecules of ATP.
- This only occurs in the presence of oxygen.
- Carbon dioxide is transported from your mitochondria out of your cell, to your red blood cells, and back to your lungs to be exhaled.
