| Popis: | The chemical free energy of ingested food can only be transduced into the mechanical energy of muscular contraction through storage as bond energy of adenosine triphosphate (ATP) (I). The process of utilizing food energy for muscular work therefore involves two distinct coupling mechanisms: a) the coupling of oxidation and phosphorylation, and b) the coupling of phosphate bond energy and contraction. Each of these coupling mechanisms may be considered separately and each therefore is a potential site for variation of efficiency. When computed from steady-state measurements of respiratory gas exchange, the effi |
