What is the final acceptor for electrons in
a. oxygen
b. ATP
c. carbon dioxide
d. hydrogen
e. water
Introduction:
Cellular respiration consists of a series of reactions that are crucial for metabolism. The reactions that are involved in this type of respiration are catabolic in nature and involve the conversion of energy from organic nutrients.
Answer to Problem 1TYK
Correct answer:
Oxygen
Explanation of Solution
Explanation for the correct answer:
Option (a) is oxygen. Oxygen acts as the final acceptor of electrons in cellular respiration, which has a series of reactions. The electrons from organic molecules are transferred to oxygen. The process also involves several reactions that form ATP (adenosine triphosphate). This cellular respiration produces ATP at the end. Hence, option (a) is correct.
Explanation for the incorrect answer:
Option (b) is ATP. ATP in cellular respiration cannot act as a final acceptor of the electrons. ATP is produced from this reaction and cannot be the ultimate electron receptor. So, it is an incorrect option.
Option (c) is carbon dioxide. Carbon dioxide is the waste product during the process of cellular respiration. Later, it is used for the preparation of organic compounds, carbohydrates. So, it is an incorrect option.
Option (d) is hydrogen. Hydrogen ions are obtained from glucose during cellular respiration; they help in the formation of water when two hydrogen ions and one oxygen ion combine together. They are released at the end of the process. So, it is an incorrect option.
Option (e) is water. Energy is produced with the help of water during cellular respiration, along with carbon dioxide. The hydrogen and oxygen molecules combine to form water. It is a byproduct of the reaction. So, it is an incorrect option
Hence, options (b), (c), (d), and (e) are incorrect.
Therefore, it can be concluded that oxygen is the final acceptor in cellular respiration, since it becomes water in the cycle, by combining with the hydrogen atoms that are released, by the end of the process.
