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
Solution
All of the above are true for Oxidation-Reduction (redox) reactions.
-
Reduction occurs when an atom or molecule gains an electron. In this process, the molecule or atom becomes more negative as it has gained an extra negatively charged electron.
-
Oxidation occurs when an atom or molecule loses an electron. This process makes the molecule or atom more positive as it has lost a negatively charged electron.
-
Oxidation of glucose releases energy that is captured ultimately in the bonds of ATP. This is the fundamental process that provides energy to most of the cells in our body.
-
Redox reactions always happen in pairs. This means that whenever a molecule is oxidized, another molecule must be reduced. This is because the electron(s) that are lost in the oxidation process are the same ones that are gained in the reduction process.
