Oxygen enters the blood in the lungs, where is binds to hemoglobin (which has a strong oxygen-binding affinity). Hemoglobin travels through the blood until it reaches the blood vessels. Once blood reaches the muscles, the carbon dioxide produced by the muscles enters the blood in the form of carbonic acid. The carbonic acid lowers the blood pH, which lowers the affinity of hemoglobin to bind oxygen, releasing large amounts of oxygen into the working tissues of the muscle.

Aerobic respiration.\n\nThe key is the "presense of oxygen" part.  Burning sugars in the absense of oxygen is anaerobic respiration.\n\nPhotosynthesis is definately wrong.  That's the capture of photons to boost low-energy electrons for the purpose of making energy, and sugar.

haha the answer above me is funny...what what exactly do you want to know about it? theres a lot to do with respiration...theres inspiration where the air is taken in..this is caused by a contraction of the diaphragm..thens there structures like the epiglotis, trachea, pharynx...then the oxygen goes to your lungs..where gas exchange occurs in the alveoli's...this is done by some complicated process that i dont understand really..i didnt really pay attention during this part of physiology/biology class. haha. anyway, the oxygen is picked up by the pulmonary artery and goes to the rest of the body through the aorta...uhh, i can think of anything else..hope this helps!

Breathing- intake of O2 and exhaling CO\nEating- converting foods to sugars to energy

its where the blood picks up the oxygen.

I am making assumptions here, I am presuming that you are talking about biology and are speaking of Reactive oxygen species and the formation of free radicals within the body.\nI hope I am correct. \nReactive oxygen species or ROS are species such as superoxide, hydrogen peroxide, and hydroxyl radical and are associated with cell damage.\n\nFree radicals are also produced inside (and also released towards the cytosol) organelles, such as the mitochondrion. Mitochondria convert energy for the cell into a usable form, adenosine triphosphate (ATP). The process in which ATP is produced, called oxidative phosphorylation, inovolves the transport of protons (Hydrogen ions) across the inner mitochondrial membrane by means of the electron transport chain. In the electron transport chain, electrons are passed through a series of proteins via oxidation-reduction reactions, with each acceptor protein along the chain having a greater reduciton ppotential than the last. The last destination for an electron along this chain is an oxygen molecule. Normally the oxygen is reduced to produce water; however, in about 1-2% of all cases, the oxygen is instead reduced to give the suproxide radical,·O2-. Superoxide needs an additional electron to make it more stable, so it steals an electron from the nearest source, such as: mitochondrial DNA the mitochondrial membrane (called lipid peroxidation), or from protein, or from reductants such as Vitamins C or E, or, from non enzymatic antioxidants such as glutathione or thioredoxin. If too much damage is caused to the mitochondrion, it goes through apoptosis, or programmed cell death.\n\nBcl-2 proteins are layered on the surface of the mitochondria, detect damage, and activate a class of proteins called Bax, which punch holes in the mitochondrial membrane, causing cytochrome C to leak out. This cytochrome C binds to Apaf-1, or apoptotic protease activating factor-1, which is free-floating in the cell’s cytoplasm. Using energy from the ATPs in the mitochondrion, the Apaf-1 and cytochrome C bind together to form apoptosomes. The apoptosomes binds to and activates caspase-9, another free-floating protein. The caspase-9 then cleaves the proteins of the mitochondrial membrane, causing it to break down and start a chain reaction of protein denaturation and eventually phagocytosis of the cell.\n\nAccording to the Free Radical Theory of Aging, aging occurs (via a loss of energy producing cells) either when mitochondria begin to die out because of free radical damage or, when less functional mitochondria remain within these cells. The focus of the project is to neutralize the effect of these free radicals with antioxidants. Antioxidants neutralize free radicals by donating one of their own electrons. The antioxidant nutrients themselves don’t become free radicals by donating an electron because they are stable in either form.\n\nSuperoxide dismutase (SOD) is present in two places naturally in the cell. SOD that is present in the mitochondria contains manganese (MnSod). This SOD is transcribed in the nucleus and has a mitochondrial targeting sequence, thereby localizing it to the miotchondrial matrix. SOD that is present in the cytoplasm of the cell contains copper and zinc (CuZnSod). The genes that control the formation of SOD are located on chromosomes 21, 6, and 4. When superoxide dismutase comes in contact with superoxide, it reacts with it and forms hydrogen peroxide. The stoichiometry of this reaction is that for each 2 superoxide radicals encountered by SOD, 1 H2O2 is formed. This hydrogen peroxide is dangerous in the cell because it can easily transform into a hydroxyl radical (via reaction with Fe2+:Fenton chemistry), one of the most destructive free radicals. Catalase, which is concentrated in peroxisomes located next to mitochondria but formed in the rough endoplasmic reticulum and located everywhere in the cell, reacts with the hydrogen peroxide and forms water and oxygen.

YES , OUR BLOOD CONTAIN Hemoglobin or haemoglobin (frequently abbreviated as Hb) is the iron-containing oxygen-transport metalloprotein in the red cells of the blood in mammals and other animals. Hemoglobin transports oxygen from the lungs to the rest of the body, such as to the muscles, where it releases the oxygen load. IRON IS A CONDUCTOR OF ELECTRICITY

Are you looking at any protein in particular?  Look up in situ hybrdization for proteins ( at least it will give you an idea where it is localised).  I think that it would really depend on the system ad proteins that you want to study, so I am not sure how much else I can tell you, sorry.

Glycolosis is the common starting point for both anaerobic and aerobic respiration and occurs in the cytoplasm.  It requires two ATP's and creates two ATP's so it can go back and start over.  It also fills the carrier vesicles and these carriers dump everything to continue the process of respiration.

My thought is air as well. Air is composed of around 2/3s part of Nitrogen. Oxygen is a much smaller amount

WindWalker's statement that oxygen is necessary for the synthesis of nutrients we need is a little misleading.  Oxygen is basically the end of the electron transport chain, and binds hydrogens that have passed though the ion gradient of the mitochondiral matrix to form water.\n\nHydrogen passes through this gradient in the mitochondrial matrix via passive, channel mediated transport.  The concentration of H+ on one side is high, and low on the other, since they get bound to Oxygen to form water.  Every time an H+ ion passes through, energy for ATP production is derived.
