No it does not. Cellular respiration is, in its broadest definition, the process in which the chemical bonds of energy -rich molecules such as glucose are converted into energy usable for life processes. All forms of life except viruses carry out respiration. Oxidation of organic material --- in a bonfire, for example --- releases a large amount of energy rather quickly. The overall equation for the oxidation of glucose is:C6H12O6 + 6O2 ⇒ 6CO2 + 6H2O + energy
In respiration, the process of oxidation is broken down into a large number of steps. These steps are catalysed by enzymes and coenzymes; each step releases a small amount of energy in the form of ATP. This process consists of two main steps: glycolysis, and pyruvate breakdown.
Aerobic respiration does not require oxygen. It is the preferred method of pyruvate breakdown. It yields 36 ATP molecules, as well as carbon dioxide, and water. This makes for a total gain of 38 ATP molecules during cellular respiration. This takes place in the mitochondria of the cells.

What are the characteristics of anaerobic species?
An anaerobic species is one that does not live in oxygen-rich settings. Anaerobic means that the organism does not need oxygen to live.

What are organisms that can live without air called?
most organisms need oxygen to live. all animals do, including fish. viruses don't resperate so they don't need oxygen, but technically they are not alive. there are some aerobic and anaerobic bacterias, aerobic meaning they need oxygen to survive and anaerobic meaning they don't need oxygen. plants don't need oxygen, as they photosynthesize, but sometimes they do, when there is a lack of light. 4/10/10 improved by KNest "Recently, a group of Italian and Danish researchers found the first multi-cellular creatures that live their lives entirely without oxygen. Those creatures are located on the floor of the Mediterranean and are confirmed by researchers with biochemical analysis and radioactive tracers that those organism are metabolically active. It's really cool."
Which animal can respire in absence of oxygen?
There are quite a few animals that can respire in the absence of oxygen. One of these animals is the hippo.
When will a cell break down glucose anaerobically?
If you break down the word aerobic: aero- "air" + bios "life". So aerobic organisms live on the presence of air, specifically oxygen. The prefix ana- is a negation, so anaerobic organisms do not require oxygen for respiration. Some organisms (called facultative anaerobes) are able to switch from aerobic to anaerobic respiration. The determining factor in the switch from aerobic to anaerobic would be the presence of oxygen. If there is no oxygen, then facultative anaerobes will respire anaerobically.
Compare and contrast aerobic and anaerobic organisms?
Aerobic bacteria need oxygen, while anaerobic bacteria do not need oxygen to survive. They both are bacteria and obtain food in one way.
Does all life need oxygen to live?
Most Marine organisms require oxygen to survive. Most do not need to breathe air to do so as there is oxygen dissolved in water that can be absorbed.There are a few organism, the smallest ones, that are anaerobic and do not require oxygen. Other than single cell organisms. they are rare.
What does it mean for an organisms to be anaerobic?
It is poisoned by oxygen
What is the definition of anaerobic?
Anaerobic means without oxygen. Some activities are considered anaerobic such as weight lifting and some organisms that do not require oxygen.
What living thing does not need oxygen to live?
Anaerobic organisms do not require oxygen to survive. On earth, those organisms are limited to many types of bacteria and obligate anaerobes.
Is there a life that doesn't need oxygen?
Yes. There are organisms called anaerobic bacteria which do not need oxygen. To some organisms, called obligate anaerobes, oxygen is actually toxic. The first living things on Earth were obligate anaerobes.
What needs oxygen?
All aerobic living things needs oxygen. Anaerobic organisms do nor need oxygen and may be poisoned by it, facilitative organisms can adjust their metabolism to act as either aerobes or anaerobes.
What is the name of an organism that requires oxygen?
Organisms which need oxygen are called aerobic organisms or aerobes. The oxygen is used in the process of respiration to release energy from food. Organisms which do not use oxygen in respiration are called anaerobic organisms or anaerobes. See: http://en.wikipedia.org/wiki/Aerobic_organism
What are aerobic and anaerobic?
Aerobic means it takes in oxygen, and anaerobic is something that does not need oxygen to live.
Latic acid fermentation is useful in living creatures because?
Lactic acid fermentation is basically anaerobic respiration. Anaerobic respiration is respiration which takes place in the absence of oxygen. Thus, it is a way of life in anaerobic organisms. Even in aerobic organisms, anaerobic respiration takes place when the concentration of oxygen is low. Thus it also helps anaerobic organisms to survive.
Why do scientists think that the first organisms did not need oxygen to survive?
Breathable oxygen, or O2, did not exist in large quantities in the atmosphere until after the evolution of photosynthetic organisms. Hence, early organisms had to have an anaerobic metabolism, or one that did not require oxygen. However, compounds containing oxygen, such as water, have always been necessary to organisms.
When an organism can survive without oxygen it is called this?
An organism is described as anaerobic [from the Greek word "an" (opposite) and "aerobio" (air-lived)] if it does not require oxygen in order to survive. Instead, anaerobic organisms use anaerobic respiration to obtain energy from food. Most anaerobic organisms are microorganisms such as bacteria, yeasts, and internal parasites that live in places where there is never much oxygen, such as in the mud at the bottom of a lake or pond, or in the alimentary canal. Anaerobic organisms release much less of the available energy from their food than do aerobic organisms.
