Oxygen is a vital gas required for the survival of all organisms that use aerobic respiration. Oxygen is the final acceptor of electron in electron transport chain which produces ATP, the cell's energy cashier. Molecular oxygen is able to be utilized and so it is easier to make available for the cells and organisms. Moreover oxygen is produced by plants freely during the process of photosynthesis.

∙ 16y agoThe term 'aerobic' means "air needing". Anaerobic organisms do not need oxygen. As to why they need oxygen, aerobic organisms utilize sugars and other carbohydrates by breaking down glucose and oxygen into carbon dioxide, water, and energy. Oxygen is a vital component in the ETC, or electron-transport-chain, the main energy maker in the mitochondria of cells. Without getting into too much detail about reduction/oxidation reactions, the oxygen is necessary to help move electrons around during the reaction.
Anaerobic organisms utilize sugars without oxygen via fermentation. An end result is ethanol (in yeast) and lactic acid (in humans and others). Aerobic respiration is much more efficient at making energy than anaerobic, and thus in humans it is used first.
However, imagine you are running a race. Your body will eventually begin to run low on oxygen, and your muscle cells may not have enough to go around to get creating energy. In this case, they switch to anaerobic respiration, a much less efficient process and creating lactic acid.
That lactic acid buildup is why your muscles start to burn! When you run for a long time and feel your legs begin to hurt, its due to the buildup of acid in your muscles cells.

∙ 15y agoAerobic organisms, that is organisms that require oxygen to live need oxygen simply as an electron acceptor at the end of the Electron Transport Chain to transport away electrons that were previously used to generate a gradient to allow the production of ATP. Without it, unbound electrons pile up at the end of the ETC, preventing further ATP production and resulting in cessation of life.

Do animal cells use carbon dioxide?
No. Animal cells use Oxygen and give off carbon dioxide as a waste product. Plant cells use carbon dioxide and give off oxygen.
Cells use oxygen to produce energy through a process called?
This process is Respiration.
What does the delivery of oxygen allow cells to do?
Oxygen is used by cells for the process of respiration. Respiration is the release of energy from food. When this happens using oxygen it is called aerobic respiration: glucose + oxygen ----> water + carbon dioxide + ENERGY IRON
What does blood contain that carrys oxygen to the cells and wastes away from the cells?
Hemoglobin is what transports the oxygen in the red blood cells.
Do animal cells respire?
Animal cells respire in order to refresh the blood cells with oxygen rich molecules. The oxygen is then transported to the rest of the body for muscle use.
What do the cells use for energy when there is no oxygen for the cells?
Cells use anaerobic respiration when there is no oxygen available.
When the oxygen is carried to cells it is used to relese what?
cells use the oxygen to release chemical energy.
Blood cells that use protein to capture and carry oxygen is?
Blood cells use a protein called hemoglobin to capture oxygen.
Do cells use carbon dioxide?
No. Animal cells use Oxygen and give off carbon dioxide as a waste product. Plant cells use carbon dioxide and give off oxygen.
What do organisms do with the oxygen they absorb from the air?
Organisms use the oxygen they absorb from the air for their cells. The cells need this oxygen in order to carry out their functions.
Do all cells use oxygen to produce energy?
No cell produces oxygen; oxygen is made in the hearts of stars. Plant cells responsible for photosynthesis, liberateoxygen from carbon dioxide molecules. Plants use the carbon to made carbohydrates (with the hydrogen from water) and the oxygen is the waste product.
Do animal cells use carbon dioxide?
No. Animal cells use Oxygen and give off carbon dioxide as a waste product. Plant cells use carbon dioxide and give off oxygen.
Where in your body is oxygen use?
In the mitochondria of your cells.
During exercise muscle cells use what?
During exercise muscle cells use oxygen.
How do cells use the energy from ATP?
they use it by giving out oxygen
Why is oxygen important to blood and other cells?
Oxygen is needed for respiration. This is how all our cells release energy. All the body cells and white blood cells therefore need oxygen. Red blood cells don't use oxygen, they undergo anaerobic respiration, but they transport the oxygen needed by other cells.
What is the use of the chemical oxygen?
oxygen is used in respiration which is carried out in all cells .
