Respiration

Respiration can be broadly defined as "the breakdown of organic compounds into simpler compounds accompanied by the release of energy in the form of ATP"

Since most often the substrate is glucose, the general equation for respiration can be written as follows:

C₆H₁₂O₆ + 6O₂ 6CO₂+6H₂O +38ATP

Or

C₆H₁₂O₆ + 6O₂ 6CO₂ +6H₂O + 2830 kJ

(glucose) (energy)
