摘要

由9个相互作用的微管偶极体组成的圆在低弯曲率下产生较少的弯矩，但在高弯曲率下可以产生弯矩，其能量效率至少为92%，与所有微管偶极体之间的相互作用排列在平行于弯曲平面的平面上相同。轴轴排列对主动剪切矩与剪切速率归一化关系的形状无显著影响。

Is the 9+2 pattern of flagellar and ciliary axonemes an efficient arrangement for generating planar bending?

A circlet of 9 interacting microtubular doublets generates less bending moment at low bending rates, but allows bending moment to be generated at higher bending rates, and has an energy efficiency at least 92% as great as an arrangement with all the interactions between microtubular doublets in a plane parallel to the bending plane. The axonemal arrangement has no significant effect on the shape of the normalized relationship between active shear moment and shear rate.
