When a quick burst of en is needed and oxygen is in limited supply
Anaerobic respiration does not require pesky oxygen.
Aerobic respiration is more efficient and releases more energy per amount of fuel used.
Aerobic respiration produces much more energy than anaerobic respiration
Efficiency is about 18 times higher. Maximum use of food
Aerobic respiration is much more efficient in producing energy, which is used as a fuel source to carry out reactions.
in anaerobic respiration energy lasts longer
not all organisms completely oxidise the glucose. it depends on whether they undergo aerobic respiration or anaerobic respiraion. in aerobic respiration glucose is completey oxidised to give out CO2 as a waste product and H2O and energy. this can be represented as Glucose------>pyruvate------> CO2 + H2O + 36 ATP Energy
organisms which do not require oxygen, infact most of them would find oxygen poisoness Like or for example yeast cells....etc
The products of Aerobic Cellular Respiration are: 36 ATP, Water and Carbon Dioxide. Of Anaerobic Respiration in Animals: Lactic Acid and 2 ATP Of anaerobic respiration in Plants: Ethanol, CO2 and 2 ATP
aerobic respiration: glycolysis, Krebs cycle, and electron transport chain anaerobic respiration: glycolysis, fermentation (lactic acid or alcohol)
ANAEROBIC RESPIRATION is how the cells produce ATP when no oxygen is present: Anaerobic (fermentation) vs. Aerobic Respiration i. Without oxygen to accept electrons in the electron transport chain, most of cellular respiration stops. ii. Fermentation enables some cells to produce ATP in the absence of oxygen. iii. In glycolysis, glucose is oxidized to two pyruvate molecules with NAD+ being reduced to NADH. iv. Pyruvate then accepts electrons from NADH, oxidizing it back to NAD+. The NAD+ is then available to oxidize more glucose. v. Because the pyruvate does not enter the Krebs cycle, there is still a lot of energy which is not removed from the fuel. This is evident in yeast fermentation where the end product is alcohol - a high energy fuel. vi. Human muscle cells switch from aerobic respiration to lactic acid fermentation to generate ATP when O2 is scarce. When O2 is absent, the ETC stops; therefore pyruvate accepts electrons, forming lactic acid. This waste product causes muscle fatigue and cramping, but it is eventually converted back to pyruvate in the liver. vii. Under aerobic respiration, a molecule of glucose yields 36-38 ATP, but the same molecule of glucose yields only 2 ATP under anaerobic respiration. Hope this helps. it is a section out of my biology notes. If it doesnt, google Anaerobic respiration and wiki will give you a good answer
aerobic respiration give more energy than anaerobic respiration.
Aerobic means "with oxygen" and anaerobic means "without oxygen." Cells produce energy at a might higher and faster rate with oxygen than without.
the mode of respiration in the absence of air ,more precisely oxygen is called anaerobic respiration. eg:-yeasts

Anaerobic respiration plays a major role in keeping us alive like when your running around and you feel out of breath anaerobic respiration takes over and give your body energy when your lungs cant
jogging or running in the park

I can give you five similarities :) (please excuse my spelling, dyslexic)Both processes realease energyBoth start with a breakdown of nutrientBoth yield productsboth take place in a cellBoth involve PyruvatesHope this helped! :D
whether aerobic or anaeerobic respiration, the cycle always starts with glucose - a 6 carbon compounds, this ithen metabolised to give 2 NADH , 2 CO2 and 2Pyruvate molecules, also, a net of 2 ATP molecules is produced. This is the main product, the whole purpose of aerobic respiration is to generate energy to carry out whatever activity the subject is carrying out. The next stage is the Kreb's cycle, this is where Acetyl CoA enters the cycle.....but this will lead to anaerobic respiration. hope this helps.
Without oxygen, pyruvic acids are not metabolized by cellular respiration but undergo fermentation. They are not transported into the mitochondria, but remain in the cytoplasm, where they are converted to waste products that may be removed from the cell.NADH is oxidized by the electron transport chain in respiration only.
Well in man, anaerobic respiration takes place during glycolysis. Glycolysis is the process by which one molecule of glucose is broken down, in the abscence of oxygen, to give energy. During glycolysis, only 2ATPs(Adenosine TriPhosphates) are given off. This means that anaerobic respiration in man does not give off much energy. meanwhile aerobic respiration which takes place during the Kreb Cycle gives off 38 ATPs, meaning that in the prescence of Oxygen, more energy is released.
