摘要： Biologists returned to contraction as a means to explaining motion within the cell in the twentieth century. This preference was a result of the discovery of the pulse motion of protoplasm, the influence of work in muscular contraction, and the transition from colloid chemistry to research on macromolecules.

Abstract:

Explanations for protoplasmic streaming began with appeals to contraction in the eighteenth century and ended with appeals to contraction in the twentieth. During the intervening years, biologists proposed a diverse array of mechanisms for streaming motions. This paper focuses on the re-emergence of contraction among the molecular mechanisms proposed for protoplasmic streaming during the twentieth century. The revival of contraction is a result of a broader transition from colloidal chemistry to a macromolecular approach to the chemistry of proteins, the recognition of the phenomena of shuttle streaming and the pulse of protoplasm, and the influential analogy between protoplasmic streaming and muscle contraction.
