    ‘redox reactions involve electron transfer’
    • ‘Instead it has been proposed that extension is a result of active redox processes.’
    • ‘Species that participate in redox reactions are described as either reducing or oxidizing agents.’
    • ‘Bacterial redox reactions with minerals are already being exploited in mining low grade or inaccessible ores.’
    • ‘In every redox reaction, an atom must increase its oxidation state and an atom must decrease its oxidation state.’
    • ‘These metals are essential for most redox reactions which, in turn, are fundamental to cellular function.’
