to cease. From the strong frequency
dependence on temperature, we derive
an activation energy of 58 kJ/
mol, which is consistent with the
cell’s metabolism involving molecular
motors such as kinesin, dynein, and
myosin. The magnitude of the forces
observed (~10 nN) suggests concerted
nanomechanical activity is operative in
the cell.
