It takes longer because the oxygen needs to travel to the mitochondria.

Aerobic respiration releases much more energy than anaerobic respiration. Aerobic respiration can result in as many as 38 molecules of ATP from one molecule of glucose, compared to a net gain of 2 molecules of ATP in anaerobic respiration.

Aerobic respiration produces much more energy than anaerobic respiration Efficiency is about 18 times higher. Maximum use of food

aerobic by far. anaerobic only makes a net of 2 ATPAerobic respiration is very much efficient. About 40%. It is about 18 times efficient

Aerobic roughly means "requiring air," with "air" meaning oxygen. The suffix "ana-" means to take the opposite, much like "un-" or "dis-". Aerobic respiration requires oxygen and anaerobic respiration does not.

There are anaerobic and aerobic types of cellular respiration. Anaerobic (including glycolysis) respiration does not involve oxygen. Aerobic (including the Kreb's, or citric acid, cycle and oxidative phosphorylation) respiration requires oxygen, and generates much more energy than anaerobic respiration.

Anaerobic - respiration without oxygen Aerobic - respiration with oxygen Aerobic is much more efficient.

because oxygen is not available, the sugar fragments cannot go through aerobic cellular respiration in the mitochondria.therefore, anaerobic cellular respiration dose not produce nearly as much usable energy (ATP) as aerobic respiration does.

respiration without oxygen present is anaerobic respiration. & fermentation occurs when oxygen is not present.fermentation= A+LSIf oxygen is not present; anaerobic respiration begins to occur. Anaerobic respiration does not need oxygen. It happens when there is not enough oxygen for aerobic respiration. Here is the word equation:glucose → lactic acid (+ energy)Much less energy is released by anaerobic respiration than by aerobic respiration.

No. Aerobic respiration is WITH oxygen. ANaerobic is without. Generally anaerobic process is fermentation, but that doesn't produce nearly as much ATP, and is therefore unfavorable for anything big, like people or animals.

Most of the cells in your body produce energy both aerobically and anaerobically depending on weather or not they have oxygen available to them, aerobic respiration (with oxygen) produces much more energy than anaerobic but takes much longer. We use anaerobic respiration when we are exercising and have a limited supply of oxygen, it is the cells in our muscles that use anaerobic respiration most.

Aerobic is less dangerous than anaerobic and anaerobic is much stinkier

During anaerobic respiration, such as fermentation, pyruvic acid and NADH form the products of alchohol and carbon dioxide and NAD+. In aerobic respiration there are many more steps in the Krebs cycle to make the products of carbon dioxide, NADH, ATP, and FADH2 from pyruvic acid.Therefore aerobic respiration is much more complex than aerobic respiration.

Anaerobic cellular respiration generates a net gain of 2 ATP. Aerobic cellular respiration generates 36 to 38 ATP.

Oxygen provides a much better Respiratory Base than that of no oxygen.

In aerobic respiration, oxygen is used by the cells to achieve complete breakdown of carbohydrates to carbon dioxide & water; large quantities of ATP are produced. Anaerobic respiration takes place in the absence of oxygen; only the glycolysis sequence occurs, and much less ATP is produced.

Yes. In more complex organism, in which aerobic respiration is the main process to make ATP, when your body does have enough oxygen it goes though anaerobic respiration. In simpler organisms, which don't require much ATP, anaerobic would be the main process.

Even though anaerobic respiration has the two significant drawbacks - lactic acid produced as a waste product; not nearly as much energy is released as with aerobic respiration - it is necessary if, for example, you are running a marathon. In this case, it won't be long before the body's demand for oxygen overtakes supply. This is where anaerobic respiration replaces aerobic respiration. Once you have finished exercising, your heart and breathing rates continue to rise, in order for you to repay your oxygen debt.

Oxygen is NOT needed to produce ATP. This is only true for Oxidative Phosphorylation. Substrate Level Phosphorylation does not require ATP at all. While ATP can be produced without oxygen via a process called anaerobic respiration, aerobic respiration is a much more efficient means of ATP production. Aerobic respiration is the release of energy from glucose or another organic substrates 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. Aerobic respiration takes place in almost all living things. It is easy to get rid of the Carbon Dioxide and excess water; this is excretion (the removal of the toxic waste products of metabolism), and maximum energy is released from the glucose. Some organisms can respire in the absence of air: this is anaerobic respiration. This does not release so much energy and it produces much more toxic waste products. However, if Oxygen is not available, anaerobic respiration is better than nothing. When this happens in our muscles we produce lactic acid which gives you cramp.

36 ATP produced during aerobic respiration

Aerobic respiration requires less ATP than anaerobic respiration, so less of the cell's energy is used if Oxygen is present.

Mainly very active cells.They need much energy amount

Aerobic Respiration contains two processes. Substrate level phosphorylation which includes Glycolysis, and the Krebs cycle a.k.a citric acid cycle and oxidative phosphorylation that includes the etc (electron transport chain) and ATP synthesis( chesmiosmosis). Anaerobic respiration only contains glycolysis and a type of fermentation either alcohol or yeast. Aerobic uses oxygen while anaerobic does not need oxygen and does NOT use oxygen. This concludes that anaerobic respiration mosty likely came first because earths early atmosphere did not contain much oxygen. Ashley Pratt and AP bio student just answered this :)

Oxygen acts as an electron acceptor in the electron transport chain, which generates much more ATP(36 ATP) than glycolysis.
