Abstract

The biochemical efficiency was measured in iodoacetate N2 and NaCN-treated muscles by dividing the work done by the amount of phosphoryl creatine hydrolysed when contracting at their optimum velocity. An inverse relationship was found between the intrinsic speed of shortening (Vmax) of the muscles and their mechanochemical efficiency.

摘要

通过将碘乙酸盐N2和氰化钠处理的肌肉在以最佳速度收缩时所做的功除以磷酸肌酸水解的量来测量其生化效率。发现肌肉的内在缩短速度（Vmax）与其机械化学效率之间呈反比关系。
