PLEASE HELP 50 POINTS FOR THIS ONE BIOLOGY QUESTION IF YOU GET IT RIGHT YOU GET BRAINLY ANSWER!!! What is the primary distinguishing factor between anaerobic and aerobic respiration?


Anaerobic respiration uses fermentation whereas aerobic respiration uses glycolysis, the Krebs cycle, and the electron transport chain.

Aerobic respiration gives off carbon dioxide whereas anaerobic respiration gives off oxygen.

Anaerobic respiration takes place without the use of oxygen whereas aerobic respiration uses oxygen at the end of the electron transport chain.

Anaerobic respiartion only takes place in yeast and bacteria whereas aerobic respiration always takes place in higher organisms such as plants and animals.

Answers

Answer:

The correct answer will be option- Anaerobic respiration takes place without the use of oxygen whereas aerobic respiration uses oxygen at the end of the electron transport chain.

Explanation:

The process of respiration evolved in the primordial time when the planet Earth was lack or devoid of oxygen in the atmosphere. So, the type of respiration evolved at that time was not dependent on the oxygen as the electron acceptor. The presence of oxygen can halt the process of anaerobic respiration.

The process of aerobic respiration evolved later in the presence of oxygen and therefore used oxygen as an electron acceptor at the end of the electron transport chain and formed the metabolic water.

Thus, on the basis of absence ad presence of oxygen differentiates between anaerobic and aerobic respiration.

Answer:

The answer to your question is the last one.

Explanation:

Anaerobic respiration uses fermentation whereas aerobic respiration uses glycolysis, the Krebs cycle, and the electron transport chain.

Both kinds of respiration uses glycolisis after this process, anaerobic respiration goes to fermentation and aerobic respiration goes to the Krebs cycle, so this answer is incorrect.

Aerobic respiration gives off carbon dioxide whereas anaerobic respiration gives off oxygen.

This answer is incorrect because aerobic respiration gives off oxygen but anaerobic respiration gives off different molecules like ethanol, lactic acid or acetic acid.

Anaerobic respiration takes place without the use of oxygen whereas aerobic respiration uses oxygen at the end of the electron transport chain.

I think this option is correct but is not the primary distinguishing factor between anaerobic and aerobic respiration, so this option is incorrect.

Anaerobic respiartion only takes place in yeast and bacteria whereas aerobic respiration always takes place in higher organisms such as plants and animals.

In my opinion, this option is correct it describes one of the primary factors that distinguish between aerobic and anaerobic respiration.

Which of the following statements concerning immunological memory is true? A. The memory response involves only B cells.
B. The memory response is due to production of long-lived memory cells that can respond very rapidly upon second exposure.
C. Antibodies produced in response to a secondary infection are mostly IgM.
D. The memory response is usually faster but not as strong.

Answers

Answer:Option B

The memory response is due to long lived cells that can respond rapidly to second exposure.

Explanation:

Immunological memory is the ability of the immune system to quickly identify and remember an antigen from a pathogen that the body has encountered before and initiate a faster immunological response upon a reencounter with the particular antigen. This dependents on colonial selection.. The memory cells have a long life span and can remain in the body for a long time. When it encounter the antigen its previously encountered for the second time, they mobilize quickly and become plasma cells, these secrets a lot of antibodies and cause a stronger reaction to defend against such antigen in a short time.
