detection of redox state
detection of redox state
The series of events in which a chemical stimulus indicating redox state is received and converted into a molecular signal. Redox state refers to the balance of oxidized versus reduced forms of electron donors and acceptors in an organelle, cell or organ; plastoquinone, glutathione (GSH/GSSG), and nicotinamide nucleotides (NAD+/NADH and NADP+/NADPH) are among the most important.
