Why is oxygen important to blood and to the cells?
Asked by Jaziya | 17 May, 2009, 11:36: AM
Expert Answer
In cellular respiration, oxygen is required to break down the complex organic substances (like glucose) obtained from food through digestion, in order to release the energy present in them. This energy is stored in the form of ATP and used whenever needed by the body for carrying out the various life processes.
