Answer:
CARBON IV OXIDE and WATER
Explanation:
When in the presence of oxygen, cells undergoes aerobic respiration which involves the breakdown of glucose into energy, water and carbon iv oxide. The carbon iv oxide and water are formed during citric acid cycle of respiration. The energy are absorbed and stored leaving water and carbon iv oxide. Carbon iv oxide is removed from the cells by diffusion into the bloodstream and removed by the lungs, converted into hydrocarnonate ions. Water is removed by diffusion from where it is removed by the kidneys as urine.
