Summary
This study explores quantum coherence in cell microtubules, suggesting energy-loss-free transport mechanisms. Experiments are proposed to detect quantum phenomena, potentially revealing new insights into cellular processes.
Area of Science:
- Quantum physics
- Cell biology
- Biophysics
Background:
- Cellular microtubules (MT) are investigated for quantum mechanical coherence.
- Exploration of energy-loss-free transport mechanisms within MTs, linking to Frohlich's theories on solitons and biological superconductivity.
Purpose of the Study:
- To discuss the potential for quantum coherence in cell microtubules.
- To propose novel mechanisms for quantum-coherent states formation within MTs.
- To suggest experimental methods for verifying the conjectured quantum nature of MTs.
Main Methods:
- Representing MT arrangements as cavities.
- Analyzing quantum-electromagnetic interactions between MT dimers and ordered water molecules.
- Drawing parallels with atomic physics experiments, specifically Rabi-Vacuum coupling.
Main Results:
- A novel scenario for macroscopic/mesoscopic quantum-coherent states formation is reviewed.
- The proposed mechanism involves interactions between MT dimers and ordered water within MT cylinders.
- A Rabi-Vacuum-splitting phenomenon in MT dimer spectra is conjectured.
Conclusions:
- The study conjectures that MTs may exhibit quantum-coherent states.
- Experimental detection of Rabi-Vacuum-splitting would confirm the coupling of MT dimers with ordered-water coherent modes.
- This could provide evidence for quantum effects in biological systems.
