Description
Summary:It is shown that enzymatic reactions with electron transfer can play the role of magnetosensitive stages of intracellular processes. The system of von Neumann-Liouville equations for the spin density matrices of the participants of ion-radical enzymatic processes in cells was solved using the steady-state approximation. Within the framework of the Δ g mechanism of spin conversion of ion-radical pairs of the substrates of enzymatic reactions, the magnetic-field dependences of the rates of enzymatic processes are calculated. Magnetic field effects can be used as evidence for the ion-radical mechanism of enzymatic reactions and as a means of determining their kinetic characteristics.
