On the basis of a quantification of the fractal dimension, D, in micrographs of cytoskeleton components or microtrabecular lattice, we propose that the cellular cytoplasm can be described as a percolation cluster, a sort of 'random fractal'. Our hypothesis deals with: (i) the existence of the percolation threshold--a remarkable property of percolation processes; and (ii) the reactivity increase--when enzymes, or targets, and substrates, or effectors, coexist in the same topological dimension.
基于对细胞骨架成分或微梁晶格显微照片中分形维数D的量化，我们提出细胞质可被描述为一种渗流簇，即一种“随机分形”。我们的假设涉及：（i）渗流阈值的存在——渗流过程的一个显著特性；以及（ii）反应性增加——当酶或靶点与底物或效应物在相同拓扑维度中共存时。
