Summary
This study reformulates the electromechanochemical model, revealing how proteins use thermal energy for catalysis and energy coupling. It introduces the concept of a pulsating protein for programmed energy redistribution in biological systems.
Area of Science:
- Biophysics
- Biochemistry
- Molecular Biology
Background:

- To elucidate the role of protein dynamics in energy transduction.
Main Methods:
- Theoretical reformulation of the electromechanochemical model.
- Conceptualization of a pulsating protein mechanism.
- Definition of the mitochondrial supermolecule.
Main Results:
- Proteins utilize thermal energy to induce strains and conformational changes for catalysis.
- Energy coupling occurs via vibrational energy transfer through proteins.
- A pulsating protein model explains programmed electromechanochemical energy redistribution.
