<strong>Cellular</strong> <strong>Respiration</strong><br />

• Harvesting energy for cellular processes<br />

– Complex organic molecules (glucose) rich in potential energy <br />

simpler waste products with the release of energy<br />

C 6 H 12 O 6 + 6O 2 6CO 2 + 6H 2 O + ENERGY (ATP+heat)<br />

• <strong>Respiration</strong> is a cumulative function of three metabolic stages<br />

• Glycolysis<br />

– Breaks down glucose into two molecules of pyruvate<br />

• The citric acid cycle<br />

– Completes the breakdown of glucose<br />

• Oxidative phosphorylation<br />

– Is driven by the electron transport chain<br />

– Generates ATP<br />

– Process occurs in the mitochondria ATP: adenosine<br />

triphosphate
