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.

- We will be starting a group project next week where you and your group will research and ultimately present on a current research article related to the biology of a pathogen that infects humans. The article could be about the pathogen itself, the disease process related to the pathogen, the immune response to the pathogen, vaccines or treatments that affect the pathogen, or other biology-related study about the pathogen. I recommend that you choose a pathogen that is currently interesting to researchers, so that you will be able to find plenty of articles about it. Avoid choosing a historical disease that no longer circulates. List 3 possible pathogens or diseases that you might want to do for your group project.arrow_forwardnot use ai pleasearrow_forwardDNK dagi nukleotidlar va undan sintezlangan oqsildagi peptid boglar farqi 901 taga teng bo'lib undagi A jami H boglardan 6,5 marta kam bo'lsa DNK dagi jami H bog‘lar sonini topingarrow_forward
- One of the ways for a cell to generate ATP is through the oxidative phosphorylation. In oxidative phosphorylation 3 ATP are produced from every one NADH molecule. In respiration, every glucose molecule produces 10 NADH molecules. If a cell is growing on 5 glucose molecules, how much ATP can be produced using oxidative phosphorylation/aerobic respiration?arrow_forwardIf a cell is growing on 5 glucose molecules, how much ATP can be produced using oxidative phosphorylation/aerobic respiration?arrow_forwardHow do i know which way the arrows go?arrow_forward
