Symbols: V, liquid volume in the closed chamber; v, volume of a single cell; a, area of a flat surface occupied by a single cell; k_a, rate constant for autoxidation of NO; k_m, rate of NO consumption by media-generated O₂⁻; K_M, the O₂ concentration at which respiration is halved in the absence of NO; K_I, constant describing inhibition of respiration by NO; D_NO and D_O2, aqueous diffusivities of NO and O₂ respectively; C₀, liquid-phase O₂ concentration in equilibrium with the incubator.
