Key Points: Respiration

Living organisms need energy for life processes. Complex organic compounds (potential energy) must be converted into a usable form (ATP) through respiration.
Respiration is a biochemical process of oxidation of organic compounds in an orderly manner to release chemical energy as ATP.
Respiratory organs are structures or systems in organisms that facilitate the exchange of gases, primarily oxygen and carbon dioxide, between the organism and its environment.
Equation - C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + 38 ATP
Gaseous Exchange - Respiration involves the exchange of gases (O₂ in, CO₂ out) between the organism and the environment. The site where this exchange occurs is called the respiratory surface.
