Why would the earliest living forms have carried on anaerobic respiration rather than aerobic?

There was not enough oxygen in the atmosphere until the anerobes made it, and then drove themselves almost to extinction.

What is anaerobic and anaerobic respiration?
Aerobic cellular respiration occurs in the presence of oxygen and anaerobic cellular respiration occurs in the absence of oxygen. Without the presence of oxygen, cellular respiration cannot go past Glycolysis (the first step of cellular respiration) and will be forced to find an alternative route which is, fermentation. Hope this helped.
Where in human is anaerobic respiration carried out in?
anaerobic respiration is carried out when the tissues in the body lack oxygen. such as during heavy exerice. the body cant pump oxygen to the tissues fast enough so they undergo anaerobic respirtation. however this causes lactic acid in the muscles and the oxygen 'debt' has to be paid back
What disrupts cellular respiration?
Cellular Respiration is a three step process; Glycolysis, the Krebs Cycle, and the Electron Transport Chain. Effective cellular respiration is an aerobic cycle, meaning that it requires oxygen. The first step, glycolysis, is an anaerobic process, meaning it does not require oxygen. Therefore, glycolysis is always able to take place. The next step is the Krebs Cycle. This is an aerobic process and does not take place in the absence of oxygen. If there is an absence of oxygen, bodily toxins such as ethyl alcohol and lactic acid are produced and cellular respiration is not carried out. To answer your question, a lack of oxygen is what disrupts cellular respiration.
What Is Aerobic metabolism is carried out in the presence of?
Aerobic is with air.Anaerobic is without air.
What from of anaerobic respiration carried out by yeast?
It produce 2 ATP per glucose molecule. Ethanol is produced as a bi product

Is wine made by aerobic or anaerobic fermentation?
Wine is made by anaerobic fermentation. It is carried out by yeast.
If oxygen is unavailable the what stages of respiration are not carried out?
the stages of aerobic respiration
Where is the process of cellular respiration carried out in prokaryotes?
Aerobic respiration in measosomes.Anerobic respiration in cytoplasm.
If oxygen is unavailable then what stages of respiration are not carried out?
aerobic :)
What are disadvantages of fermentation when compared to the processes aerobic and anaerobic respiration?
The equation for anaerobic respiration is: glucose ---> lactic acid + carbon dioxide + energy To know the disadvantages of anaerobic respiration it is best to compare it to aerobic respiration which involves oxygen (glucose + oxygen ---> carbon dioxide + water + energy) For humans to respire regularly and for long periods of time, oxygen is required. This means that anaerobic respiration through humans causes a lack of oxygen, and cannot be carried out for a very long time. Lactic acid is also produce and this is toxic and causes things such as cramp to build up. Anaerobic respiration also produces very little energy compared to aerobic respiration so is not suitable for every day respiration! Humans will mostly breathe anaerobically in situations such as sprinting in a race.
Where does the aerobic process of cellular respiration take place?
Aerobic respiration is an almost universal process - carried out by most animals and plants.It consists of several stages, the first of which is shared with anaerobic respiration and takes place in the cytoplasm of cells. The purely aerobic reactions take place inside mitochondria, small specialized organelles within the cytoplasm of all body cells. More active cells have more mitochondria.

What are the organelles where aerobic respiration takes place?
Mitochondria is an organelle present in both plant and animal cells. This is where the process known as cellular respiration happens.
When a person is no longer able to deliver enough oxygen to muscle cells during heavy exercise the cells begin to carry out anaerobic respiration which is the same type carried out by many bacteria?
Yes. They begin use lactic acid fermentation, a type of anerobic respiration.
How do aerobic and anerobic resiration differ?
Fermentation is the process of deriving energy from the oxidation of organic compounds, such as carbohydrates, using an endogenous electron acceptor, which is usually an organic compound.[1] This is in contrast to cellular respiration, where electrons are donated to an exogenous electron acceptor, such as oxygen, via an electron transport chain. Fermentation does not necessarily have to be carried out in an anaerobic environment, however. For example, even in the presence of abundant oxygen, yeast cells greatly prefer fermentation to oxidative phosphorylation, as long as sugars are readily available for consumption.[2] Cellular respiration is the set of the metabolic reactions and processes that take place in organisms' cells to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products. The reactions involved in respiration are catabolic reactions that involve the oxidation of one molecule and the reduction of another.
