Quantum walks and signal transduction pathways
  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.
