Answer:
The correct answer is - mitochondria.
Explanation:
The reaction the generates the energy by the oxidation and reduction reaction that takes place in the cell is cellular respiration which converts biochemical reaction from the nutrients to ATP which is the currency of the energy in living beings.
The cellular respiration has three-stage glycolysis ( takes place in the cytoplasm), Oxidative decarboxylation and TCA cycle. Oxidative decarboxylation and TCA cycle take place in the mitochondria which involves oxidation of pyruvate and reduction of NAD+ in this process.
Thus, the correct answer is - Mitochondria.
