Explanation / Answer

ANSWER:

The process of synthesis of ATP in the mitochondria is also known as oxidative phosphorylation. Mitochondria import fatty acids and pyruvate, which areused as sources of energy for subsequent reactions. oxygen acts as the final electron acceptor in the mitochondrial electron-transport chain. NADH produced in the citric acid cycle donates electrons to the electron-transport chain. A molecule of acetyl-CoA is fed into the citric acid cycle and is converted into carbon dioxide, which is released as a waste product.

EXPLANATION:

Oxidative phosphorylation also known as electron transport chain.

Mitochondria generate most of the cell energy called as adenosine triphosphate (ATP). Mitochondria uses fatty acids and pyruvate, which are used as sources of energy for further reactions.

Electron carriers are reduced during glycolysis and donate electrons and protons to the electron carrier proteins of the ETC. The final electron acceptor is oxygen. Together with oxygen, electrons and protons it forms water.
