We receive 34 ATP out of the 36-38ATP from oxygen during cell respiration. The other 2-4ATP is food energy (glucose).
The air that we breathe in 78% nitrogen, 21% oxygen, and 1% carbon dioxide, water vapor, and other gases. We only need the oxygen though, so we breathe out the other gases with the carbon dioxide that our body produces during respiration. So to answer your question, it is nitrogen, but we breathe it in and then out- we don't use it. The only gas we use is oxygen to breathe.
Concentration of oxygen in dry air is 20,946 %.
Firstly, tanks rarely provide oxygen - they usually provide simple air or other breathable gas. Pure oxygen would kill you if you breathed it deeper than about 30 feet.Second, the average scuba tank holds the equivalent of about 80 cubic feet of gas under pressure. At the surface that would be enough to breathe off for about three hours for an everage person. But the deeper you go, the faster you consume gas because you breathe it under greater pressure.
To determine the energy produced from 8.52 moles of oxygen, we need to know the specific reaction taking place, as different reactions yield different amounts of energy. For example, in cellular respiration, the complete oxidation of one mole of glucose (which requires 6 moles of oxygen) produces about 2870 kJ of energy. If we assume a similar reaction, we could calculate the energy based on the stoichiometry of the reaction and the energy yield per mole of oxygen. Without additional details about the specific reaction, we cannot provide an exact energy value.
Trees and other plants "breath out" oxygen as a by-product of Photosynthesis - This is how plant use sunlight to turn carbon dioxide "breathed in" from the atmosphere, plus taken up by the tree's roots, into sugars and starches which they stores and use for energy to power all their life processes. Like you and me, trees also "breath in" a little oxygen and "breath out" a little Carbon dioxide when it is dark, as part of "respiration" which is how sugars are burnt in our bodies to produce energy for our life processes. So yes - trees do absorb oxygen, but much, much less than they give out for us to breathe in.

lool well oxygen is pretty much needed for life. oxygen is used for oxidation purposes in our metabolism to synthesise ATP (energy), that's why you breathe it in. Without oxygen, you woudlnt be alive.
when i have a cold, it is hard for me to breathe. i don't have much energy. why do you think this happen
no they get energy from the food they consume. we use sugar that is pretty much present in everything and the oxygen we breathe in, and our cells react these together to produce energy. of course, this is aerobic respiration. some organisms of capable of respiring anaerobically and therefore have no use for oxygen at all
The same amount you wil just breathe in more often
Oceans generate about 50-80% of the oxygen we breathe, primarily through photosynthesis by phytoplankton and algae. This oxygen production plays a crucial role in regulating the Earth's atmosphere and supporting marine life.
Typically, the air you breathe is comprised of 18 to 21 percent Oxygen.
because without oxygen you cant breathe.
Grass produces about half of the oxygen we breathe in a day.
because we use up oxygen much faster than we use up the energy in food.
When you are at rest or asleep, your body's need for oxygen decreases because your metabolic rate and energy expenditure are lower. As a result, your respiratory system slows down to match this reduced demand for oxygen. This helps conserve energy and allows your body to continue functioning efficiently without over-exerting itself.
