What are the final electron acceptor in electron transport chain?

Answers

Answer 1

Answer:

In aerobic respiration, the final electron acceptor in the electron transport chain is oxygen. It accepts two electrons and a molecule of water is formed as a by product.

In anaerobic respiration, the final electron acceptor in the electron transport chain is pyruvate. Anaerobic respiration commonly occurs in the muscle tissue of animals as a result of intense activity or exertion. Pyruvate is used as makeshift electron acceptor in place of oxygen and is reduced or converted to lactic acid.

Answer 2

Answer:

Final answer:

In the electron transport chain involved in aerobic respiration, oxygen plays the essential role of final electron acceptor. It receives low-energy electrons and forms water, allowing the process to continue and ATP to be produced. This chain also allows for the creation of various other biochemical molecules.

Explanation:

The final electron acceptor in the electron transport chain, which is a part of aerobic respiration, is oxygen. As electrons are passed down the electron transport chain, from NADH or FADH₂, they lose energy. This journey through a series of redox reactions creates an electrochemical gradient used in chemiosmosis, contributing to the production of ATP.

Oxygen is the final receiver of these low-energy electrons. In combination with hydrogen ions, it forms water, which is one of the end products of the electron transport chain. Consequently, the presence of oxygen is crucial for the functioning of the electron transport chain and the production of ATP, our body's primary energy currency.

ATP generation is only one of the many functions of the electron transport chain. Other biochemical molecules, such as nonessential amino acids, sugars and lipids, can also be produced from intermediate compounds of glucose catabolism. These molecules, in turn, can serve as energy sources for glucose pathways.

The fruit fly represented in the diagram below has unusual, curled wings that formed after exposure to radiation. In order for the fly to pass this trait on to its offspring a change has to occur

Answers

Answer:

the gametes of the fly

Explanation:

i took the test and got this question right

I'm not sure what the question is, but the only traits that are passed down are the ones that can be found in the germ (sex) cells. Radiation exposure alters somatic (body) cells usually, but can also alter germ cells, so it depends.

Petroleum and coal can be mined from the continental shelf. True or false

Answers

The correct answer would be true. Petroleum and coal are mostly mined from the continental shelf. Most of the oil rigs are found and situated in this area. Gas/oil deposits are found in these areas since the ocean floor is known to exist a 100 million years ago which means deposits and fossil fuels are formed all through out those years.

In the Strange Situation, Latoya basically ignored her mother, was not upset when she left the room, and did not seek her out when she returned. Mary Ainsworth would most likely classify Latoya as: Group of answer choices insecure antisocial. securely attached. insecure resistant. insecure avoidant.

Answers

Answer:

The best answer to this question: Mary Ainsworth would most likely classify Latoya as:___, would be: Insecure avoidant.

Explanation:

When forming relationships with other people, especially during the first years of life, the way that parents interact with their children will be vital to define how, in later years, these same children will be able to bond with other people. In the case of Latoya, it is evident that she does not want, or does not care, that her mother is in the room with her; she does not seek her, she ignores her mother and was not upset if her mother was not there with her. Latoya´s attitude shows a lack of attachment to her mother, even a rejection, to her, for a reason that is unknown. Furthermore, it would seem as if Latoya were avoiding anything that has to do with her mother, to the point of ignoring that she is even there. These are typical attitudes of children that have formed an insecure avoidant bond with another person.

In sexually reproducing organisms, mutations can be passed on to the organism's offspring if the mutation occurs in what

Answers

The answer is the germ cells.

Mutation can occur in any type of the cell - either germ cells or somatic cells. Germ cells give rise to the gametes. If the mutation occurs in these cells, the change will be present in gametes, too. This way mutation can be passed on to the next generation. On the other hand, somatic mutations (mutations in the somatic cells) are not passed on to the next generation.
