Is respiration organic?
Cellular respiration, in a nutshell, is a serial flow of electrons through the cell membrane, from oxidizable substrates (like sugars) to the ultimate electron acceptor (like oxygen), resulting in generation of energy, which is utilized for various cellular processes. When the ultimate electron acceptor is oxygen it is called aerobic respiration, whereas when the ultimate electron acceptor is the elemental sulfur or copper or a ferric ion (in the absence of oxygen) it is called anaerobic respiration. But when the oxidizable substrate was an inorganic hydrocarbon chain and the electron acceptor was an inorganic element, such as one of the above elements, occurring through an inorganic membrane, it may be called 'inorganic respiration', which was the way the initial respiratory process took place and the purpose of this was to keep the membrane potentials 'alive'.
Is nitrogen required in the stage of respiration?
Yes, oxygen is the fuel for respiration... oxygen + glucose = carbod dioxide + water + Energy However, the carbon dioxide and oxygen for a plant or tree would be the other way round because plants breath in co2 and give out oxygen.
What does cellular respiration remove from the air?
Carbon Dioxide
Is anaerobic respiration and breathing the same thing?
Anaerobic respiration is a form of respiration using electron acceptors other than oxygen. Although oxygen is not used as the final electron acceptor, the process still uses a respiratory electron transport chain; it is respiration without oxygen. In order for the electron transport chain to function, an exogenous final electron acceptor must be present to allow electrons to pass through the system. In aerobic organisms, this final electron acceptor is oxygen. Molecular oxygen is a highly oxidizing agent and, therefore, is an excellent acceptor. In anaerobes, other less-oxidizing substances such as sulfate (SO42-), nitrate (NO3-), sulfur (S), or fumarate are used. These terminal electron acceptors have smaller reduction potentials than O2, meaning that less energy is released per oxidized molecule. Anaerobic respiration is, therefore, in general energetically less efficient than aerobic respiration(?). Anaerobic respiration is used mainly by prokaryotes that live in environments devoid of oxygen. Many anaerobic organisms are obligate anaerobes, meaning that they can respire only using anaerobic compounds and will die in the presence of oxygen. Breathing is the process that moves air in and out of the lungs. Aerobic organisms of these types—such as birds, mammals, and reptiles—require oxygen to release energy via respiration, in the form of the metabolism of energy-rich molecules such as glucose. Breathing is only one process that delivers oxygen to where it is needed in the body and removes carbon dioxide. Another important process involves the movement of blood by the circulatory system. Gas exchange occurs in the pulmonary alveoli by passive diffusion of gases between the alveolar gas and the blood in lung capillaries. Once these dissolved gases are in the blood, the heart powers their flow around the body (via the circulatory system). The medical term for normal relaxed breathing is eupnea. In addition to removing carbon dioxide, breathing results in loss of water from the body. Exhaled air has a relative humidity of 100% because of water diffusing across the moist surface of breathing passages and alveoli.
What is the byproduct of respiration?
False Co2...carbon dioxide (dont read this if u dont want to) there are different forms of respiration, aerobic respiration= oxygen + glucose -> carbon dioxide+ water (+energy) anaerobic respiration=
What process do certain prokaryotes use nitrates or sulfates rather than oxygen as the terminal electron acceptor?
"Anaerobic respiration" doesn't require oxygen. True anaerobic respiration involves an electron acceptor other than oxygen. Bacteria are capable of using a wide variety of compounds as terminal electron acceptors in respiration: nitrogenous compounds (such as nitrates and nitrites), sulfur compounds (such as sulfates, sulfites, sulfur dioxide, and elemental sulfur), carbon dioxide, iron compounds, manganese compounds, cobalt compounds, and uranium compounds.

Does aerobic respiration produce carbon dioxide and water?
Yes. Aerobic respiration produces carbon dioxide and water. Also, oxygen is the terminal electron acceptor

The oxygen consumed during cellular respiration is involved in what process?
Oxygen consumed during cellular respiration is involved in the electron transport chain; it is the final electron acceptor (this is also what makes it either aerobic or anaerobic respiration).
What do animals produce at the end of anaerobic respiration?
The whole point of cellular respiration is the production of ATP. If it is anaerobic respiration you end up with 2 ATP molecules, if it is aerobic respiration you end up with 32 Atp molecules. Glycolosis, Krebs cycle, and the Electron transport chain are the three main components of aerobic cellular respiration.
Chemolithotrophs?
oxidize reduced inorganic chemicals to produce energy 2) Use alternate terminal electron acceptor other than oxygen -> Usually carbon dioxide or sulfur 3) Usually members of the domain Archaea 4) Some anaerobic chemoorganitrophs produce ATP via anaerobic respiration through the oxidation of organic molecules -> Also use terminal electron acceptor other than oxygen -> Sulfur and sulfate are common 5) Other anaerobic chemoorganitrophs produce energy through fermentation -> Produce energy through substrate phosphorylation only
Aerobic respiration has the production of what over anaerobic respiration?
Aerobic respiration forms carbon dioxide and water vapour producing glucose while anaerobic respiration forms carbon dioxide and lactic acid.
Is a product of anaerobic respiration?
The products of aerobic respiration are water and carbon dioxide. The products of anaerobic respiration are carbon dioxide and either lactic acid or alcohol. The waste product of anaerobic respiration is lactic acid (in animals). In plants, ethanol is the waste product.
What 2 processes are involved in anaerobic respiration?
Anaerobic Respiration can occur in plant and animal cells, in the absence of oxygen.Animal CellsC6H12O6 (glucose) ---> 2 lactic acid + 2ATPPlant CellsC6H12O6 ---> ethanol + carbon dioxide + 2ATPThe two processes that occur are:1 - Glycolysis (occurs in the cytosol of cells): The glucose molecule is split into two pyruvate (3- carbon molecules). As a result, energy is released and forms 2 ATP molecules released as well as 2 loaded acceptor molecule called NADH.-(Since anaerobic respiration occurs in the absence of oxygen, it can no longer continue its journey to the Krebs Cycle and the Electron Transport Chain.)2 - Fermentation: The hydrogens from the 2 NADH molecules. In animals, The NADs will then reattach these hydrogens onto the middle carbon atom in the pyruvate (3- carbon) molecule. This produces 2 lactic acid molecules, for each pyruvate molecule. In comparison, in plants, ethanol and carbon dioxide is produced.
Differences between anaerobic respiration and aerobic respiration?
Aerobic Respiration is a respiration of a bacteria with oxygen. Glucose + Oxygen --> Energy + Water + Carbon Dioxide Anaerobic Respiration is a respiration of a bacteria without the presence of oxygen. Glucose -- > Energy + Carbon Dioxide -----by vigneshsherlekar Aerobic Respiration is a respiration of a bacteria with oxygen.

What are the products that anaerobic respiration produce?
the products for anaeribic respiration is carbon dioxide and water
Does respiration use oxygen?
If by respiration you mean cell respiration, then yes oxygen is consumed in the process of cell respiration. As a matter of fact, oxygen is the last electron acceptor in the electron transport chain, the last stage of cell respiration. In cell respiration, you produce ATP, which is essentially used by your body to get energy. That is why you need oxygen! !!
