Respiration is a Chemical Reaction
Aerobic respiration requires oxygen and is defined as the chemical reactions in cells that use oxygen to break down nutrient molecules to release energy
It is the complete breakdown of glucose to release a relatively large amount of energy for use in cell processes
It produces carbon dioxide and water as well as releasing useful cellular energy
