What are the waste products of respiration?

Carbon dioxide and water. When glucose is taken up by the cells, the mitochondria in the cells break down the glucose into molecules of energy that can be used by the cells called ATP. To make ATP from glucose requires oxygen. Once the glucose has been broken down into as many molecules of ATP as possible, there are products left over and these are water and carbon dioxide. These are excreted by every cell in the body and removed by the blood stream.
