what is the journey of an oxygen molecule?

Answer 1

Once it enters your lungs it is absorbed through the moist one cell thick wall of an alveoli into your blood. It attches itself to a haemoglobin (pontefract liquorice cake) which then deposits it in a muscle somewhere and is used for respiration. I believe it the combines with Carbon to make Co2 and then is sent back out of your lungs. That's one journey anyway.

Answer 2

well as the other contributor says the oxygen enters the lungs crosses over the membrane in the alveoli, and then enters the blood stream. From there it can get involved in many different biochemical reactions. Passing thorough many different catalyst systems, or cycles. But in simplest terms it will react with glucose and give rise to the production of carbon dioxide and water and energy.(ATP) The body then utilises this energy to carry out the tasks that are required to keep all our biological systems in balance (homeostasis). The carbon dioxide is expelled through the lungs, or in the urine. So in the end the oxygen either ends up back in the atmosphere, or is flushed down the loo.

Answer 3

Which molecule and which journey.

When I inhale an oxygen molecule it journeys to my lungs, passes through a membrane, attaches to a red blood cell, travels through the arteries and capillaries to a cell site where it transfers to a cell, participates in respiration, ultimately attaches to a carbon atom as part of a CO2 molecule which exits the cell, and is carried in the blood stream through capillaries and veins until it is transferred to the lungs and exhaled. That is one possible journey.

Their is also the similar journey of the oxygen molecule (starting as oxygen atoms in a CO2 molecule, perhaps one that somebody recently exhaled) that is absorbed by a plant, and ultimately photosynthesized into an oxygen molecule that is released to the environment.

The interesting journey of the oxygen molecule that is sucked into my car engine and converted into water or CO2 by oxidation with gasoline could also be told as an elaborate tale involving passage through the various parts of an internal combustion engine.

There are lots of oxygen molecules going through lots of journeys. Because oxygen is an atomic componant in many many substances, their journeys are innumerable.

Answer 4

Extremely extensive:
Oxygen reacts with almost everything.

You breath it in and it travels around in your blood
Bound to a carbon atom and breathed out
Circles the globe
Brought in by plant and broken free of carbon atom
Circles globe some more
Bound to CH4 - which breaks apart and oxygen bonds to 2 hydrogen atoms to make water.
Follows water cycle for a while in ocean etc.
Someone drinks it
And now I'm bored you can do the rest.
Bare in mind this has been happening since the beggining of time. That oxygen atom existed as long as the Universe. It saw the formation of our planet and got caught by our gravity. Its never destroyed.

Answer 5

it is form of an prolonged technique yet i will make it short. once you inhale, oxygen is seize by utilising blood hemoglobin in the capilaries of the lungs. Blood hemoglobin carry oxygen returned to the middle and pump out to the the remainder of the physique (which incorporate on your muscle cells). Now, your muscle cells have "myoglobin" that have greater suitable affinity for oxygen than "hemoglobin" on your blood. subsequently, myoglobin merely takes the oxygen marvelous of from hemoglobin whilst the blood flow to muscle groups.

Answer 6

that would depend entirely on the route it takes.

Answer 7

shut up
