What condition's does a cell use fermentation instead of cellular respiration?
low oxygen
Describe the main difference between cellular respiration and burning?
Cellular Respiration is when cells get energy from carbohydratesso, the difference beween this and a fire is that this happens inside your body from carbohydrates
The breakdown of glucose for energy is called?
Fermentation
Why is cellular respiration called a aerobic procecc?
Because it requires oxygen from the air. Oxygen is combined with carbohydrates to produce carbon dioxide and water: C6H12O6 (aq) + 6O2 (g) → 6CO2 (g) + 6H2O Aerobic comes from the greel "aero" meaning air, and "bios" meaning life. It refers to things which live in the presence of oxygen found in air which is 21% oxygen. Aerobic respiration means the kind of respiration typically performed by aerobic organisms. Anaerobic respiration is that respiration done in an environment devoid of "air" (meaning the oxygen part of air).
What does cellular respiration do to oxygen levels?
glucose would go through glycolysis and in the absence of oxygen, pyruvate would turn into lactic acid since there would be no oxygen to collect the excess hydrogens/ or if yeast is involved, alchol would be produced
What type of cellular respiration occurs with oxygen?
Aerobic respiration is the type of cellular respiration that requires oxygen. This process involves the release of glucose for energy.Aerobic respiration requires oxygen to be present because it is the final electron acceptor at the end of the electron transport chain. If it is not present, then the electron can not go through the chain and fermentation will cycle instead. Fermentation is much more inefficient in producing ATP (a differenence of 32 ATP).
Why is ATP production during cellular respiration characterized as indirect?
ATP is not produced directly by the ETC but instead via the proton gradient generated during electron transport through the ETC.
Under what conditions does a use fermentation instead of cellular respiration?
low oxygen
Why do organisms cellular respiration?
Cellular respiration is one of the processes that cells perform. Organisms do not perform this process. Instead they perform respiration. Cells use cellular respiration to obtain one of the three sources needed for them to live- oxygen. Without this process, cells would not be able to perform other functions.

Breaking down food for energy without using oxygen is?
Anaerobic cellular metabolism/respiration.Oxygen is used as the ultimate electron acceptors in the electron transport chain which produces a proton gradient for the chemiosmosis (ATP formation). Certain organisms use nitrate or sulfate instead of oxygen. Fermentation is an example of anaerobic respiration.
The breakdown of glucose for energy is called?
Fermentation
Why is cellular respiration aerobic?
The single most important biochemical especially to us is " Cellular respiration ". Because this is how we derive energy from what we eat and used in some metabolic reactions and muscle contraction, nerve impulses.or in simple "Cellular respiration" is process from which the organisms can derive energy from the metabolic reactions.cellular respiration is starts from glucose. During cellular respiration one mole of glucose and six moles of molecular oxygen going to produce six carbon dioxide, six water molecules, and energy and 38 ATP's ( energy currency for biological system )Under cellular respiration :1) Glycolysis/ anaerobic cellular respiration ( breaking up glucose; gluc= sweet, ose = sugar ): It occurs completely under the absence of oxygen. so it this is called " anaerobic cellular respiration ".where in Glycolysis the glucose molecule need 2ATP's and generates 2ATP's so it generates a net of 2 ATP's.the byproducts of glycolysis that re-engineeredand enters in to aerobic( requires oxygen ) cellular respiration process called ;2) Krebs cycle( aerobic cellular respiration ) : Krebs cycle generates another 2 net ATP's. This 2ATP's produces NADH.3) Electron transport chain/ ETC ( aerobic cellular respiration ) : ETC generates 34 ATP's by using the NADH which are produced from the ATP in Krebs cycle.this cycle requires oxygen so aerobic respiration.that's about cellular respiration and aerobic process ( 2nd and 3rd ).Here some important thing is some of the byproducts of the glucose ; instead of going in to Krebs and ETC cycle enters into a process called Fermentation and produces alcohol and lactic acid.( Yeast= alcohol, called alcohol fermentation)( Humans= lactic acid) .
How might an organism benefit by carrying Out fermentation instead of cellular respiration?
Organisms prefer cellular respiration over fermentation.Cellular respiration gains a cell 38ATP molecules per every glucose molecule.Fermentation only gains 2ATP per glucose molecule.Obviously, you can see the difference. Cellular respiration provides much more energy for the cell, and this is why they prefer this over fermentation.There are organisms like facultative anaerobes that can preform either process, but they do cellular respiration if oxygen is available. These organisms only preform fermentation if they are in an "oxygen debt." (Like when you run, you are using a lot of energy, and you cannot get enough oxygen for cellular respiration. You are in "oxygen debt," and your muscle cells start doing fermentation. But your muscle cells prefer using aerobic reparation (cellular respiration) so you start panting. Once you get your breath back, oxygen is restored and your cells again preform cellular respiration and get more energy faster.)However, there are still obligate anaerobes that are poisoned by oxygen, and only use fermentation.Hope this helped!!
Is an anaerobic bacterium an organism that will carry out cellular respiration?
Yes, in a sense Cellular respiration is just another term for METABOLISM - The Process of Life. Metabolism will use either of the Respiratory Processes - aerobic or anaerobic {with or without Oxygen} - to make the mandatory energy molecule Atp. Photosynthesis is an aerobic way to provide energy, and Chemosynthesis is the anaerobic way - using, say H2S as the electron donor {instead of say CH4} to produce energy [via the production of Atp] to provide Glucose for Respiration. [It would appear that bacteria at deep-sea-thermal-vents use sulfur to make glucose for Standard Respiration].
