Respiration

Respiration is the breakdown of large glucose molecules into simple molecules such as carbon dioxide and water with the simultaneous release of energy inside living cells. It is an enzyme mediated process.

Main processes:
Glycolysis (glucose to pyruvate, occurs in cytosol)
Link Reactions (pyruvate to acetyl CoA, occurs in intermembranal space)
Krebs cycle (acetyl CoA to carbon dioxide, occurs in the matrix)
Oxidative phosphorylation (occurs in the inner membrane)
