ResumoThis chapter discusses the mitochondrial system of enzymes. The transformation of energy from one form to another is accomplished in living systems by specialized structures and biochemical machines. The chloroplast system of green plants converts radiant energy to the chemical energy of adenosine triphosphate (ATP); the mitochondrion couples the synthesis of ATP to the oxidation of citric cycle intermediates. The energy transformations are brought about by the intracellular structures of a high degree of complexity. The understanding of how these machines function requires knowledge of the component parts, what each part does, and how the parts fit together. Enzymic reactions underlie all biological energy transformations. The biochemical machine not only facilitates the enzymic process that leads to the energy transformation, but also provides for the molecular contiguity of the energy-transforming system and the system that is activated by the energy so transformed. The study of biochemical machines lies at the crossroads of physiology, biochemistry, and physics.
