Anaerobic is defined as being able to exist without, or not requiring air or oxygen. Most often, anaerobic is used to define a cell or organism that lives without oxygen. The term may also be used to describe a process or function that occurs without air.Know More
The word anaerobic is from the French word, anaérobie, coined by Louis Pasteur in 1863. It is from the Greek an- ("without") + aer ("air") + bios ("life"). The opposite word is "aerobic," meaning requiring oxygen or air.
In humans, anaerobic organisms are typically found in the gastrointestinal tract. Some anaerobic bacteria produce important toxins.Learn more about Biology
Aerobic and anaerobic respiration are the two types of cellular respiration that occur in the cells of living organisms. Aerobic respiration requires oxygen, while anaerobic respiration can occur in the absence of oxygen.Full Answer >
Unicellular microorganisms, called obligate anaerobes, strictly use anaerobic respiration for energy production. Common examples of obligate anaerobes are some species of bacteria, such as Clostridium tetani, Clostridium botulinum, Clostridium perfringens, Clostridium sporogenes and Clostridium difficile.Full Answer >
Examples of anaerobic respiration include nitrate reduction, denitrification, sulfate reduction and carbonate reduction. All of these methods use an electron acceptor other than oxygen and have a membrane-bound electron transport system. These anaerobic mechanisms also synthesize adenosine triphosphate, or ATP, through ATP synthase.Full Answer >
The two main types of anaerobic respiration are alcoholic fermentation and lactic acid fermentation. These methods of respiration occur when the amount of oxygen available is too low to support aerobic respiration.Full Answer >
