Carbon dioxide is one of the breakdown products of glucose during aerobic respiration in humans. (Yeast can produce carbon dioxide during alcoholic fermentation, but people do lactic acid fermentation which doesn't make CO2.)
The carbon dioxide is removed from remnants of glucose during a transition phase and during the citric acid cycle of respiration.
NOTE: The oxygen in carbon dioxide is NOT the oxygen that we breathe in. That oxygen is used at the end of the electron transport chain part of aerobic respiration to accept the H+ and electrons.

When we breathe in oxygen, our cells use it to stay alive. Carbon dioxide is a metabolic waste-product that is produced from the work that the cells do with the oxygen.

Carbon in the food we eat. Oxygen in the air we breath.
