None of the above

Detailed explanation-1: -During oxidative phosphorylation, electrons derived from NADH and FADH2 combine with O2, and the energy released from these oxidation/ reduction reactions is used to drive the synthesis of ATP from ADP.
Detailed explanation-2: -In general, the main energy source for cellular metabolism is glucose, which is catabolized in the three subsequent processes-glycolysis, tricarboxylic acid cycle (TCA or Krebs cycle), and finally oxidative phosphorylation-to produce ATP.
Detailed explanation-3: -This process is known as oxidative phosphorylation, because the phosphorylation of ADP to ATP is dependent on the oxidative reactions occurring in the mitochondria.
Detailed explanation-4: -This process, the use of energy to phosphorylate ADP and produce ATP is also known as oxidative phosphorylation.
Detailed explanation-5: -Electron Transport Chain is the process by which NADH and FADH2 are oxidized and a proton gradient is formed. Oxidative phosphorylation is the process of making ATP by using the proton gradient generated by the ETC.
