Interconnecting chain segments stretched

Association of oil-like groups of certain chain segments between attachments stretch other interconnecting chain segments. 

On stretching (pulling), the interconnecting chain segments develop elastic force. 

The stretched interconnecting chain segments either retract and pull the attachment sites closer together or increase the force sustained at immovable attachment sites. 

As with the elastic-contractile model proteins discussed in Chapter 5, favorable hydrophobic association (in this case of RIP globular protein tip with the Q site) stretches interconnecting chain segments. Thus, the answer to the question asked by Crofts et al. ° in the title of their article, becomes clear Interactions of quinone with iron-sulfur protein of the bci complex Is the mechanism spring-... 

E.2.9.2 Hydrophobic Associations Stretch Interconnecting Chain Segments... 

Elastic forces come into play as hydrophobic associations stretch interconnecting chain segments. Only if the elastic deformation is ideal does all of the energy of deformation become recovered on relaxation. To the extent that hysteresis occurs in the elastic deformation/ relaxation, energy is lost and the protein-based machine loses efficiency. Thus, the elastic consilient mechanism, whereby the force-extension curve can be found to overlay the force-relaxation curve becomes the efficient mechanical coupler within the vital force. The objective now becomes one of understanding the age-old problem of a reluctance to discard past idols. 

Formation of the hydrophobic association between the hydrophobic tip of the Rieske Iron Protein and the hydrophobic ubiquinol-containing site stretches an interconnecting chain segment. This extended chain segment functions as a free-standing tether originating from an anchor in the membrane and bridging...
