which gas is made during respiration?
912145
CO2 - the carbon atoms possibly are derived from hydrocarbons in food, and the oxygen atoms are, of course, from the atmosphere.

CO2 is the byproduct as it is given out after energy is taken by burning the food in the tissues .energy is not the byproduct of respiration.it is the ultimate product due to which we get energy to sit in frnt of the computer.lol(xcuse the bad pun)

breathing is just lungs.  respiration has to do with the blood getting oxygen.\n\nand there are 2 types of respiration too.  one with chemistry.  not sure about that one.

Respiration is much more efficient than fermentation and respiring organisms, including us, have come to dominate the earth. Fermenting organisms are restricted to niches where oxygen is lacking (or they are at an advantage) and suitable carbon sources exist. Again, the diversity of respiring microbes is vast, but they do have many things in common.\n\nATP is generated by ETLP involving a membrane system. \n\nThe energy yield from respiration is much higher than fermentation and the substrate often has all available electrons removed; it is fully oxidized.\n\nThe terminal electron accepter is inorganic. For aerobic respiration this is oxygen, but bacteria are also capable of using nitrate, sulfate, methane and others.\n\nSubstrates for respiration include\n\nOrganic molecules - Sugars, amino acids, nucleotides, organic acids, fats. Some microbes can even catabolize benzene or toluene. The point is, the list is large.\n\nInorganic - Certain groups of bacteria are capable of using an inorganic compound as their source of electrons. For example iron bacteria will start with Fe+2 and oxidize it to Fe+3. Sulfur oxidizing bacteria will take inorganic sources of sulfur (H2S) and oxidize them.\n\nProducts of Respiration tend to be highly oxidized.\n\nOrganic molecules are most often oxidized to CO2 and H2O. \n\nInorganics change to CO2, N2 and SO4-2

Aerobic respiration requires oxygen in order to generate energy. It is the preferred method of pyruvate breakdown from glycolysis and requires that pyruvate enter the mitochondrion to be fully oxidized by the Krebs cycle. The product of this process is energy in the form of ATP (Adenosine Triphosphate), by substrate-level phosphorylation, NADH and FADH2. The reducing potential of NADH and FADH2 is converted to more ATP via an electron transport chain with oxygen as the "terminal electron acceptor". Most of the ATP produced by cellular respiration is by oxidative phosphorylation, ATP molecules are made due to the chemiosmotic potential driving ATP synthase. Respiration is the process by which cells obtain energy when oxygen is present in the cell.\n\nTheoretically, 36 ATP molecules can be made per glucose during cellular respiration, however, such conditions are generally not realized due to such losses as the cost of moving pyruvate into mitochondria. Aerobic metabolism is rather more efficient than anaerobic metabolism. They share the initial pathway of glycolysis but aerobic metabolism continues with the Krebs cycle and oxidative phosphorylation. The post glycolytic reactions take place in the mitochondria in eukaryotic cells, and at the cell membrane in prokaryotic cells.\n\nGlycolysis\nMain article: Glycolysis \nGlycolysis is a metabolic pathway that is found in all living organisms and does not require oxygen. The process converts one molecule of glucose into two molecules of pyruvate, and makes energy in the form of two net molecules of ATP. Four molecules of ATP per glucose are actually produced but two are consumed for the preparatory phase. The initial phosphorylation of glucose is required to destablise the molecule for cleavage into two triose sugars. During the pay-off phase of glycolysis four phosphate groups are transfered to ADP by substrate-level phosphorylation to make four ATP and two NADH are produced when the triose sugars are oxidised. Glycolysis takes place in the cytoplasm of the cell. The overall reaction can be expressed this way:\n\nGlucose + 2 ATP + 2 NAD+ + 2 Pi + 4 ADP → 2 pyruvate + 2 ADP + 2 NADH + 4 ATP + 2 H2O + 4 H+ \n\nOxidative decarboxylation\nMain article: Oxidative decarboxylation \nProduces acetyl-CoA from pyruvate. This oxidation reaction also releases carbon dioxide as a product.\n\nKrebs cycle/Citric Acid cycle\nMain article: Citric acid cycle \nWhen oxygen is present, acetyl-CoA enters the citric acid cycle, and gets oxidised to CO2 while at the same time reducing NAD to NADH. NADH can be used by the electron transport chain to create further ATP as part of oxidative phosphorylation. To fully oxidise the equivalent of one glucose molecule two acetyl-CoA must be metabolised by the Krebs cycle. Two waste products, H2O and CO2 are created during this cycle, .\n\nOxidative phosphorylation\nMain articles: Oxidative phosphorylation , Electron transport chain , Electrochemical gradient, and ATP synthase\n\nIn eukaryotes, oxidative phosphorylation occurs in the mitochondria. It comprises of the electron transport chain that establishes a proton gradient (chemiosmotic potential) across the inner membrane by oxidising the NADH produced from the Krebs cycle. ATP is synthesised by the ATP synthase enzyme when the chemiosmotic gradient is used to drive the phosphorylation of ADP.\n\nTheoretical yields\nThe yields in the table below are for one glucose and molecule being fully oxidised to carbon dioxide. It is assumed that all the reduced coenzymes are oxidised by the electron transport chain and used for oxidative phosphorylation.

Air molecule???\nThe air we breath, Oxygen Nitrogen (not nitrate, just oxygen and nitrogen), goes in through your nose down to your lungs. Your red blood cells have tiny holes on them, and they "collect' the oxygen from your lungs, back to the heart, and gets pumped everywhere through your body. Your body takes the oxygen, have a bunch of reactions with them, and sends out the "waste" (carbon dioxide, etc), which goes back to your ticker, pumps it up to your lungs, and is breathed out. \n\nPlease, don't just use that as your research paper. It is much more detailed. :P

Oh Biology, how do I miss thee!!!!!  Ah that was some good times.  Cytochrome c oxidase is part of the respiration cycle and it accepts electrons.  That about all I can remember but thanks for the points and a trip down memory lane.

If this is for your GCSE next week I think it's high time you got hold of a textbook and read through the section on cellular respiration as if your very life depended on it, and started regretting all the messing about you did in class when you should have at least been making some bare essential notes on this stuff. Perhaps see if your local library opens sundays if you already lost / burnt your school textbook.\n\nTo be more helpful, in brief:\n\nBreathing DOES NOT = "respiration". That's an old, outdated and confusing term for it that no-one should use any more (we now use "ventilation") .... yeah, i recognise this as something i had on my own GCSE years ago by the way :-)\n\nActual respiration is the act of metabolism, and in a vague sense, "living life" by the cell itself - the using up of raw materials ("food" e.g. glucose, and oxygen) to produce usable or storable energy (e.g. for movement, carrying out chemical reactions) and releasing less energetic waste materials (carbon dioxide, water).\n\nAerobic respiration releases a large amount of energy for each unit (eg molecule) of glucose supplied, as it uses oxygen (for what, don't worry for now, as that's degree-level stuff i still can't properly grasp... it accepts electrons, there you go :-) and allows the byproducts of early glycolysis to undergo conversion to pyruvate and enter the krebs cycle. You get... what was it... 18 molecules of energy-storing ATP out of each glucose molecule when it's involved this way.\n\nAnaerobic respiration is a more basic, primitive form of getting energy from glucose (or similar molecules), where the reaction is pretty much that you take the glucose and split it into two fructose molecules, gaining 2 ATP in the process. That's it. No oxygen required, but some less friendly waste materials e.g. lactic acid are produced. This is mainly used in bacteria, which tend to find themselves in food-rich environments, have very little energy requirement for vigourous life, and few worries about buildup of waste materials .... it is also the reason you die if suffocated, and get pains in your legs if you overexert yourself - the body cells can't make enough energy from their limited glucose supplies to survive without using the krebs cycle, and the mass build up of lactic acid in oxygen-starved muscles is very damaging.\n\nThere you go hows that for a textbook answer. That'll be a bag of fizzy cola bottles please. Mmmmmm.\n(That all came off the top of my head, but ONLY because i've been through that particular bloody mill four times so far - GCSE, A-Level, Biology degree and clinical training)\n\ngood luck

Physically, gases are produced by evaporation from liquids or sublimation from solids. Dissolved or absorbed gases can be freed by changes in pressure or temperature, too.\n\nChemically, gases can be produced during reactions, wherever small molecules are produced that cannot be dissolved in the solvent.\n\nSpecific (or purified) gases have specific methods of production, be it in the lab, in the nature, or industrially.

Yes gasses in the air (oxygen, nitrogen, CO2, etc.) dissolve in the water (hence the fish and algae breath). Also many pollutants also dissolve in water (much easier than the gasses). If they are present in the air they will dissolve in the water, either by transfer (just the pollutants, not the gasses) or with the gasses.

O2 is an energy-rich oxidizing substance.  Sugar and fat are both energy-rich reducing substances.  When an oxidizer and a reducer react, electrons are exchanged, in what is called a redox reaction.  The redox reaction here creates CO2 and H2O, both of which are low-energy molecules.  The energy pulled out is used to make ATP (adenosine triphosphate), which fuels the body's activities.\n\nRespiration is where O2 is taken from the air and CO2 is released back in the air.  The epithelial tissue in the lungs is very, very thin, and there are many small blood vessels there which bring the blood close to the air.  O2 from the air is inhaled into the lungs, where it diffuses through the epithelium and into the bloodtream, and binds rather loosely to a substance called hemoglobin.  Likewise, the CO2 diffuses through the epitheluim and into your lungs, which you exhale. As the heart pumps, it pulls the oxygen-rich blood away from your lungs, toward the heart.  Then it is pumpmed out by the heart, going throughout the body to provide oxygen to the tissues.  As the hemoglobin goes to places deficient in oxygen, the oxygen will be released by the hemoglobin to supply the tissues.  Meanwhile, the CO2 byproduct in the tissues will bind to the hemoglobin (rather loosely) and be carried away.  After going past the tissues of the body, the blood, now oxygen poor, is returned to the heart, with a lot of CO2.  That blood is again pumped by the heart towards the lungs, and the exchange repeats all over again.

Well, oxygen is used for respiration, and carbon dioxide is only used for photosynthesis. Respiration should occur throughout the day for survival (duh), and photosynthesis can only occur when sunlight is present. So, the ans should be (c)
