Detailed explanation-1: -cellular respiration, the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water.
Detailed explanation-2: -At each cell in your body, oxygen is exchanged for a waste gas called carbon dioxide. Your bloodstream then carries this waste gas back to the lungs where it is removed from the bloodstream and then exhaled.
Detailed explanation-3: -Final answer: Carbon dioxide is a waste byproduct of cellular respiration. This is removed out of the body by the lungs.
Detailed explanation-4: -Carbon dioxide and water are created as byproducts. The overall equation for aerobic cellular respiration is: In cellular respiration, glucose and oxygen react to form ATP. Water and carbon dioxide are released as byproducts.
Detailed explanation-5: -While the water and energy are useful to animal cells, they have no need for carbon dioxide. So it is breathed out of the lungs to remove it from the body. This is why carbon dioxide is considered a waste product in humans.
