The loss of electrons from a substance involved in a redox reaction.Group of answer choicesreductionoxidation

What is true for Oxidation-Reduction (redox) reactions?Group of answer choicesReduction occurs when an atom or molecule gains an electron.Oxidation occurs when an atom or molecule loses an electron.Oxidation of glucose releases energy that is captured ultimately in the bonds of ATP.they always happen in pairsall of the above

In a redox reaction, what happens to the substance that undergoes reduction?*gains electrons and has a decrease in oxidation numberloses electrons and has an increase in oxidation numberloses electrons and has a decrease in oxidation numbergains electrons and has an increase in oxidation number
