Catalysis of the reaction: NADH + H+ + 2 monodehydroascorbate = NAD+ + 2 ascorbate. Catalysis of an oxidation-reduction (redox) reaction in which NADH or NADPH acts as a hydrogen or electron donor and reduces a quinone or a similar acceptor molecule. Catalysis of the reaction: 2-hydroxy-1,4-benzoquinone + NADH + H+ = NAD+ + 1,2,4-benzenetriol. Catalysis of the reaction: NADH + H+ + a quinone = NAD+ + a quinol. Catalysis of the reaction: NAD(P)H + H+ + a quinone = NAD(P)(+) + a hydroquinone. Catalysis of an oxidation-reduction (redox) reaction in which NADH or NADPH acts as a hydrogen or electron donor and reduces a hydrogen or electron acceptor. Catalysis of an oxidation-reduction (redox) reaction, a reversible chemical reaction in which the oxidation state of an atom or atoms within a molecule is altered. One substrate acts as a hydrogen or electron donor and becomes oxidized, while the other acts as hydrogen or electron acceptor and becomes reduced. Catalysis of the reaction: NADPH + H+ + quinone = NADP+ + semiquinone. Catalysis of the reaction: NADPH + H+ + p-benzoquinone = NADP+ + hydroquinone.
