respiration
respiration 1. Oxidative reactions in cellular metabolism involving the sequential degradation of food substances and the use of molecular oxygen as a final hydrogen acceptor;
ATP, carbon dioxide, and water are the products thus formed
.
2. The physico-chemical processes involved in the transportation of oxygen to and carbon dioxide from the tissues.
