Oxygen is required as the last electron carrier for the electron transport chain, or ETC. The ETC is necessary to aerobically process NADH, FADH2, and the other energy carrying products of the citric acid cycle. If there is no oxygen, then it is inefficient for the body to run the CAC, thus only glycolysis is performed, and the produced NADH is processed by anaerobic means to free up more NAD+ for continued processing. However, the amount of energy generated by anaerobic means is far less than that produced by aerobic means.

∙ 13y agoWhat happens if you need energy, but run out of oxygen? Fermentation happens. It is the break down of glucose to make energy when there is no oxygen. It produces less energy than respiration. A by-product is lactic acid, which causes sore muscles.

∙ 12y agoCellular respiration takes three steps: Glycolysis, Krebs cycle (also know as citric acid cycle) and electron transport/chemiosmosis. During the final step, oxygen acts as a trash service and comes in to pick up the low-energy electrons and the hydrogen atoms, forming water. If oxygen is not present to remove the "waste" operations in the mitochondria (Krebs cycle and electron transport) cease. Glycolysis carries on, with a result of fermentation instead of cellular respiration.

True or false if an animal cell stops carrying out cellular respiration will it die?
true- if cellular respiration stops then an animal will not be able to breathe.
Can cellular respiration occur without photosynthesis?
Yes.Cellular respiration always need glucose. So if photosynthesis stops,organisms cannot respire
How many ATP do you get after cellular respiration?
ATP is used for cellular respiration. It is not a product of cellular respiration.
The cells of a redwood tree require oxygen for the process of?
Cellular Respiration
Is exhalation and inhalation known as cellular respiration?
No; that is known as "respiration," not "cellular respiration."
True or false if an animal cell stops carrying out cellular respiration will it die?
true- if cellular respiration stops then an animal will not be able to breathe.
If an animal cell stops carrying out cellular respiration will it die?
yea
What happens if oxygen is not persent after glycolysis?
the entire process of cellular respiration stops
Does night and day affect cellular respiration in a plant?
No, respiration is continuous. Photosynthesis stops at night, as it is light dependent.
Can cellular respiration occur without photosynthesis?
Yes.Cellular respiration always need glucose. So if photosynthesis stops,organisms cannot respire
How many ATP do you get after cellular respiration?
ATP is used for cellular respiration. It is not a product of cellular respiration.

Cellular Respiration
Is exhalation and inhalation known as cellular respiration?
No; that is known as "respiration," not "cellular respiration."
What are the difference cellular respiration and respiration?
Oxygen is the difference! Cellular respiration requires oxygen, while cellular fermentation does not.
During a normal 24 hour day when do your cells carry out cellular respiration?
Always. Your cell constantly needs energy in the form of ATP generated by cellular respiration to conduct vital activities such as transcription, translation, and sometimes replication. If cellular respiration stops, the cell will most likely die from necrosis or apoptosis in short order.
If cellular respiration stops occurring will the animal die?
yes, it willm, because, celluar respiration is critical for a cell to continue to live
Where does Cellular Respiration Occur.?
cellular respiration occurs in the mitochondria
