  Signal transduction pathways recover a crucial role in cellular processes:
they represent a connection between environmental conditions and cellular
reactions. There are many pathways and they all are related to create a
network. But how can every protein find the right way more fast than possible?
How can it find the right down-streaming kinase in the cellular sea and not
another very similar kinase? Every signal transduction pathway can be seen as
two distincted processes: the signal must reach every kinase and then it must
travel through the enzyme until its active site: quantum walks could be the
answer to both the questions.
