[Carotenoids in an excitable membrane during action potential generation and at rest]

A mathematical model is proposed for describing the kinetics of changes in the state of C40-carotenoids under rhythmic excitation of the nerve and changes of the membrane potential. The model includes cooperative and Koulon interactions of carotinoid molecules with Na+, K+, Ca2+, H+. Changes in the state of the carotinoid molecule after rhythmic excitation may be described by the restoration of the membrane potential and functioning of electrogenic Na+, K(+)-ATPase.
