It is a pity that these terms were ever used since they cause confusion.\n'External respiration' really describes breathing - ventilation of the lungs. So why not just refer to it as breathing?\nGas exchange is what happens at a respiratory surface, which in the case of lungs is the alveolar surfaces.\n'Internal respiration' describes the biochemical processes inside individual cells where glucose is respired to provide energy (in ATP molecules). This process uses oxygen and makes carbon dioxide.\n\nAll living things respire.\nOnly some breathe.

The quick and easy answer is that fermentation is the conversion of sugars to energy without oxidation (thus alcohol is a byproduct).  Respiration uses oxidation to gain energy.  Respiration typically is more efficient in converting molecules to energy.

Respiration happens constantly in many organisms as the main metabolic pathway to provide the cell with ATP (chemical energy).  \n\nThe term respiration also implies that oxygen is needed (this is why your lungs and etc are called the respiratory tract).  Oxygen is the final electron acceptor in the "electron transport chain" of respiration and when it accepts these electrons it forms a water (H2O) molecule\n\nRespiration is coupled with mitochondria in humans and most other eukaryotes.  In humans, mitochondria are used to create a "proton gradient" which drives ATP synthesis in the mitochondria.  Heart cells have many mitochondria for example, and this is because the heart constantly beats and requires energy.  Skeletal Muscle cells also have a decent amount of mitochondria, but when you exercise your muscles and they burn, it is because respiration is going as fast as it can, but since your cells need chemical energy, they have started to use an alternative pathway that produces lactic acid (the burn from exercise).\n\nEven bacteria like e-coli use respiration, though they do not have mitochondria, though often bacteria can live without oxygen and use different metabolic pathways in the absence of oxygen.

There are two kinds of respiration: aerobic (with oxygen) and anaerobic (without oxygen).  Aerobic respiration doesn't seem to vary much in creatures that undergo it with respect to the products it creates.  However, anaerobic respiration can have several different results, two of which are ethanol and lactic acid formation.  \n\nEthanol is created in alcoholic beverages by placing yeast in the presence of some sort of sugar, and placing it in an anerobic environment (like a bottle if you're making wine), and then it is allowed to sit for a while so that the yeast can convert the sugars to ethanol.  \n\nSimilarly, your muscle cells are normally undergoing aerobic respiration, but if you run a long distance, the muscles start using up all the oxygen avaliable to them, so they convert to anaerobic respiration, the by product of which is lactic acid.  Lactic acid causes the cramps in the muscles that you feel after a long, hard work out.

Aerobic Respiration\nI  INTRODUCTION \n\nAerobic Respiration,  biochemical process in living things whereby sugars and similar substances, resulting from the digestion of food, are broken down in the presence of oxygen to produce water, carbon dioxide, and energy. "Aerobic" means "with oxygen". The reaction can be represented by the general chemical equation \n\nC6H12O6 + 6O2 → 6CO2 + 6H2O + energy\n\n\nIn words, sugars and oxygen react together to produce carbon dioxide and water with the release of chemical energy. In biology, the term “respiration” is also used for the physical process of breathing in animals, and for the general chemical process in animals, plants, and microbes of obtaining oxygen from the surrounding air or water. To distinguish from these, the biochemical processes of aerobic respiration and the closely related anaerobic respiration are sometimes termed “cellular respiration” (see Metabolism).\n\nII  CHEMICAL RESPIRATION AND ENERGY \n\nAll living organisms require energy to carry out life processes such as bodily growth, repair, and reproduction. This energy is obtained by chemically breaking the energy-rich bonds in organic “fuel molecules”, usually sugars and similar carbohydrates, which are obtained from digested food. In cells, this energy is transferred to molecules of adenosine diphosphate (ADP), which are converted in the process to adenosine triphosphate (ATP). These high-energy ATP molecules are the main immediate source of useable energy for cell activities.\n\nIII  TWO STAGES OF AEROBIC RESPIRATION \n\nThe whole process of aerobic respiration contains more than 20 chemical steps or stages. The first series of stages is known as glycolysis. This occurs in the jelly-like cytoplasm of the cell, and it is anaerobic—that is, it does not require oxygen. It releases only a small proportion of the total energy available from a fuel molecule of glucose or a similar sugar. (The second series of stages is known as the citric acid cycle, tricarboxylic acid cycle, or Krebs cycle. It is aerobic—that is, it requires oxygen. It releases far more energy, compared to glycolysis, from the remainder of each sugar molecule. This series of stages happens inside the tiny organelles (parts inside the cell) called mitochondria. The food molecule is broken down in a step-by-step process that produces ATP molecules at almost every stage.\n\nIV  PRODUCTS OF AEROBIC RESPIRATION \n\nIf one molecule of a sugar such as glucose is broken down completely during aerobic respiration, it yields 38 molecules of high-energy ATP. Up to eight of these come from the first, anaerobic stages (glycolysis). The other 30 are obtained from the second, aerobic or oxygen-requiring stages of the Krebs cycle.\n\nAlmost all organisms, including plants, animals, fungi, and bacteria, use aerobic respiration. It is the reason that we and other animals breathe or respire, to obtain oxygen from air. However, some simpler organisms and cells can respire anaerobically when oxygen is absent. A few organisms, such as microbes at the bottom of the deep sea, are unable to respire aerobically at all. These are known as obligate anaerobes.\n\nAnaerobic Respiration\nI  INTRODUCTION \n\nAnaerobic Respiration, also called anaerobiosis, biochemical process in living things whereby sugars and similar substances, resulting from the digestion of food, are broken down to release energy in the absence of oxygen. "Anaerobic" means "without oxygen". It thus differs from the allied process of aerobic respiration, which requires the presence of oxygen. Life processes such as growth and repair of tissues require energy, and this is obtained by the chemical breaking of bonds in organic molecules such as sugars and other carbohydrates present in digested food. The chemical energy released by this process in cells is transferred to molecules of adenosine diphosphate (ADP), which become converted to adenosine triphosph

diffusion or gaseous exchange.\non inhaling, oxygen moves through the layer of mucus lining the alveoli and diffuses thru the alveoli cell through the capillary pores and into the blood cells binding with the haemoglobin. \non exhaling, carbon dioxide moves the opposite way. out of the capillary pores, thru the alveoli wall, thru the mucus into the alveoli

Anaerobic respiration occurs without oxygen.  In yeast, it produces carbon dioxide and alcohol, in humans, it produces lactic acid and carbon dioxide.

Plants DO breathe oxygen, the same way we do. Respiration is the most effective energy producing process there is.\nPlants, however, can perform another process (photosynthesis) in which they take up CO2 and use the energy of sunlight to build up sugars and starches from this CO2. THEN they can use these starches in the process of respiration, the same way we do (we take sugars and "use" oxygen to take out the energy contained in them)\nSo the only difference betwen us and plants is that they make their own fuel out of CO2 , but we must eat it. But we both breathe oxygen in order to get the energy out of it.\nAs to why the don't breathe hydrogen... you'd have to ask god.... but normally when hydrogen combines with things it requires energy instead of giving rise to it, so it wouldn't be too advantageous\nSo it's not that we produce the CO2 so plants can live. Plants could live without animals, we're the parasites here hehehehe

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.

We need to discuss your use of the word respiration, first.  In biology, respiration refers to the formation of energy on a cellular level.  I think what you are referring to here (unless I'm way off base) is ventilation, or the air going in and out.  \n\nThe nasal cavities of mammals are complex so as to keep the air in the cavity a bit longer to condition it--warm it up and humidify it.  If this was not done, the air going into the lungs would be cooler, meaning the body would have to expend a larger amount of energy to maintain the temperature.  If it wasn't humidified, then the body would lose more water than it can replace, causing an imbalance there.\n\nIn human,s there are structures called turbinates that disturb the air flow to allow for the conditioning.

Aerobic respiration is the release of energy from glucose or another organic substrate in the presence of Oxygen. Strictly speaking aerobic means in air, but it is the Oxygen in the air which is necessary for aerobic respiration. Anaerobic respiration is in the absence of air.
