Answer: The correct answer is CO₂ (carbon dioxide) is produced by the mitochondria in cells within our body.
Step-by-step explanation:
Respiration within humans occurs aerobically and CO₂ is produced as part of that process when cells in the body make energy. The cellular respiration process in the mitochondria converts vital nutrients into energy in the presence of oxygen. The bi-product CO₂ is removed using dissolution in the bloodstream by binding it with hemoglobin and transporting it to the lungs for exhalation.
