Abstract
A model is presented that is intended to provide a realistic physical picture of the energy-transfer mechanism in cell microtubules. A class ical phi4 model in the presence of a constant electric field is used a s a conceptual basis. It is demonstrated that kinklike excitations ari se as a result of the guanosine 5'-triphosphate (GTP) hydrolysis and t hat an intrinsic electrical force may cause them to propagate along a microtubule. A discussion is given on the possible effects of these ex citations on the dynamics of microtubules.
