Answer 1

Oxidative phosphorylation is the process of ATP synthesis in the mitochondria. Glucose and fatty acids are imported by mitochondria as sources of energy. Oxygen acts as the final electron acceptor in the electron-transport chain.

The process of synthesis of ATP in the mitochondria is also known as oxidative phosphorylation.

Mitochondria import glucose and fatty acids, which are used 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 produ

Answer 2

The question has some editing mistakes, the correct question is as following:

The process of synthesis of ATP in the mitochondria is also known as oxidative phosphorylation. Mitochondria import _______and________, which are used as sources of energy for subsequent reactions. __________________ acts as the final electron acceptor in the mitochondrial electron-transport chain. __________________ produced in the citric acid cycle donates electrons to the electron-transport chain. A molecule of ________________ is fed into the citric acid cycle and is converted into __________________, which is released as a waste product.

Answer:

pyruvate

fatty acids

Oxygen

NADH

acetyl-CoA

carbon dioxide

Step-by-step explanation:

Oxidative phosphorylation is defined as the process in which electrons are transferred from NADH or FADH2 to O2 that results into ATP formation.

This process takes place in mitochondria and act as a ATP source in aerobic organism. Pyruvate formed by the breakdown of glucose (glycolysis) and fatty acid and citric acid cycle act as energy sources and produces NADH and FADH2, that contains a pair of electrons having a high transfer potential. In the citric acid cycle, acetyl-CoA is oxidized and produces carbon dioxide as a waste product. The electrons are accepted by oxygen in the mitochondrial electron-transport chain and reduce it to water and liberate a large amount of energy which further used to generate ATP.

Hence, the correct answers are pyruvate, fatty acids, Oxygen, NADH, acetyl-CoA and carbon dioxide.
