  • anonymous
Aerobic respiration occurs when your cells produce energy in the presence of oxygen. Aerobic respiration is the process most living things undergo to use food energy.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.
