Introduction to the model
The diffusion through the nanotubes is a fast process. This speed can be partially explained by the passive diffusion through the tubes. But what if it is faster? The article from Dubey and Ben-Yehuda suggests that the diffusion is an active process. Several points can be opposed to this statement:
- First, the diffusion is happening with molecule of different natures, that have nothing to do with the natural compoments of a cell
- Unlike the mamalian cells, the tube seems to have no "railroad" design for such a transport
The question is: can we immagine a process that is faster than passive diffusion but does not rely on specific interractions?
The answer is probably yes, and in this page we propose a new model, really challenging for the mind, but that can play a role in the diffussion process
