Bacteria that are obligate anaerobes release energy from food by undergoing fermentation or anaerobic respiration. Fermentation involves the partial breakdown of organic compounds without the use of an external electron acceptor, producing compounds such as lactic acid or ethanol as byproducts. Anaerobic respiration utilizes alternative electron acceptors such as nitrate or sulfate in the absence of oxygen to generate energy through the electron transport chain.
What else can I help you with?
What happens to anaerobic organism in presence of oxygen?
mostly they die. oxygen is highly reactive and creates free radicals which destroy cell membranes. by the way the very same process is killing us slowly day by day, cell by cell... take a breath :)
In fermentation cells release energy without what?
in fermentation, cells release energy without
Are bacteria autotrophs or heterotrophs?
Both types of bacteria exist. Some are autotrophic while others are heterotrophic. Most autotrophic bacteria can synthesize their food from substances like hydrogen sulphide. This process is called chemosynthesis and involves the use of chemical substances for the production of energy. Heterotrophic bacteria, in contrast, cannot synthesize their own energy and must consume organic matter for energy. These include decomposing bacteria, or other groups of bacteria that may be symbiotic of parasitic in nature.
What are the best ways to save energy?
Energy cannot be saved.!!!! However, physical or chemical sources can release more or less energy as appropriate. This release is then transferred ( the energy) to another form/source.
What substance does respiration release energy from?
it comes from foood like buiscuitand other protein food.
Bacteria that only grows with the absence of oxygen?
Anaerobic bacteria are microorganisms that thrive in environments without oxygen. These bacteria obtain energy through fermentation or anaerobic respiration. They play important roles in processes like decomposition and digestion.
How do obligate aerobes and obligate anaerobes differ?
Answerobligate aerobes require oxygen by using cellular respiration or fermentation in order to survive. obligate anaerobes do not require it and will die if they are exposed to oxygen.
Organisms that are poisoned by oxygen and must live in very low oxygen regions are called?
Obligate anaerobes are poisoned by O2 and use fermentation or anaerobic respiration
How do you think these bacteria obtain food and energy?
They are anaerobes and do not need oxygen. They are consumers and make energy by fermentation.
Does yeast need oxygen specifically o2 to survive if not what kind of oxygen or compound molecule etc does it need to survive?
Yeast species either require oxygen for aerobic cellular respiration (obligate aerobes) or are anaerobic, but also have aerobic methods of energy production (facultative anaerobes). Unlike bacteria, there are no known yeast species that grow only anaerobically (obligate anaerobes). Yeasts grow best in a neutral or slightly acidic pH environment. (Wikipedia:Yeast)
Bacteria that can survive without oxygen are?
Anaerobic bacteria are able to survive and grow in environments without oxygen. These bacteria use alternative electron acceptors, such as nitrate or sulfate, for energy production in the absence of oxygen. Examples of anaerobic bacteria include Clostridium species and Methanogens.
What is obligate anaerobe and faculative anaerobe?
Obligate aerobes are organisms that thrive in oxygen and require it to live (make ATP for energy). Obligate anaerobes are the exact opposite (require the absolute absense of oxygen to survive, and use fermentation to make ATP). Facultative anaerobes can survive with or without oxygen, but do better with oxygen.
What living thing does not need oxygen to live?
Anaerobic bacteria are living things that do not require oxygen to survive. These organisms can produce energy through other metabolic processes that do not involve oxygen, such as fermentation or using alternative electron acceptors.
Is a yeast a living organism?
Yeasts are chemoorganotrophs as they use organic compounds as a source of energy and do not require sunlight to grow. The main source of carbon is obtained by hexose sugars such as glucose and fructose, or disaccharides such as sucrose and maltose. Some species can metabolize pentose sugars, alcohols, and organic acids. Yeast species either require oxygen for aerobic cellular respiration (obligate aerobes), or are anaerobic but also have aerobic methods of energy production (facultative anaerobes). Unlike bacteria, there are no known yeast species that grow only anaerobically (obligate anaerobes). Also, because they are adapted to them, yeasts grow best in a neutral pH environment
Why do bacteria reproduce quicker in an aerobic environment?
Not all bacteria do. Some can not grow in the presence of oxygen. Those that do (obligate aerobes and facultative anaerobes) grow quicker in oxygen since it facilitiates their energy cycle and ideal environment.
What kind of bacterial requires oxygen?
Obligate aerobes are bacteria that require oxygen for their growth and survival. They rely on aerobic respiration to generate energy.
What bacteria can survive without the presence of oxygen?
Archaebacteria called extremeophiles have some species that live entirely anaerobically. Bacteria [and other organisms] that respire using O2 as the 'final' electron acceptor are termed to be Aerobic, while bacteria [and the odd organism] that has the biochemical capacity to Live without O2 are termed to be Anaerobic.
