Definition. Respiration is the metabolic process of most living things in which food molecules (glucose) are turned into usable energy for the cell (ATP). It is the anti-process to photosynthesis, in which plants use sunlight and carbon dioxide to build food molecules, releasing oxygen as a waste product.During aerobic respiration, oxygen is present, and helps the process to crank out energy very efficiently.Some organisms can also undergo anaerobic respiration, in which oxygen is absent and a somewhat less efficient method of metabolism takes place.t is the anti-process to photosynthesis, in which plants use sunlight and carbon dioxide to build food molecules, releasing oxygen as a waste product.
