Does anaerobic cellular fermentation use the same final electron acceptors as aerobic respiration?
No, because the electron acceptor is what cates the electrons as the leave the electron transport chain, which is oxygen in aerobic respiration. Since aerobic respiration uses oxygen, and anaerobic fermentation is abest of oxygen, anaerobic fermentation cannot possibly use oxygen as respiration does.
Why it is necessary for oxygen to be the final electron acceptor in aerobic respiration?
In the biological world, oxygen is one of the most electronegative elements there is. In the ETC, electrons are passed down the various proteins and cytochromes in redox reactions. But the only way for this to work is if the next electron acceptor is more electronegative than the previous. This means that the last acceptor of electrons has to be the most electronegative. Most organisms use oxygen as the last electron acceptor, though sulfur and nitrogen can be used in extreme environments where there isn't sufficient oxygen.
How do microbial fuel cells work?
When an organism respires it produces electrons which are normally passed to a terminal electron acceptor. For many organisms this is oxygen. In environments where there is no oxygen, such as in sediments and in soils, organisms use different terminal electron acceptors. Common alternatives are Nitrate and Sulphate but some bacteria are known to use solid compounds as a terminal electron acceptor. There are some species of bacteria that can use iron as a terminal electron acceptor. The ability of some bacteria to reduce (that means give electrons to) iron in sediments is exploited in Microbial Fuel Cells. The microbes (bacteria) reduce an electrode (called the anode) by using it as a terminal electron acceptor as they metabolise (eat) high energy compounds such as sugars. By linking the anode to another electrode (called the cathode) you can make a circuit that electrons can flow through. Just imagine it like a battery, the anode is the negative terminal and the cathode is the positive terminal and the electrons come from the sugar, pass through the bacteria (giving it energy on the way) and are then passed to the anode.
What is electron configuration of H2SO4?
We use electron configuration for atoms or ions. You can't use it for compounds.
How can you use atom electron nucleus and electron cloud in the same sentence?
Electron in an atom is represented by electron cloud around the nucleus
What substance acts as the final electron acceptor in the electron transport system?
Element. Oxygen is the final electron acceptor. Some organisms can use alternative electron acceptors such as sulphate and nitrate they are known as anaerobes.
What does aerobes use as the final electron acceptor at the end of an electron transport chain?
Oxygen
What type of cell respirtaion use oxygen?
Aerobic cellular respiration. Remember, oxidative phosphorylation can take place without the use of oxygen as the final electron acceptor.
Why is oxidative respiration unable to occur without oxygen?
Oxygen is needed as the final electron acceptor for the electron transport chain on the inner mitochondrial membrane. Note: Some organisms use other molecules in this role however oxygen is the most effective.
Account for the inability of aerobes to grow in the absence of O 2?
their enzyme system necessitates use of O2 as the final hydrogen (electron) acceptor in the complete oxidative degradation of high-energy molecules such as glucose.
Does anaerobic cellular fermentation use the same final electron acceptors as aerobic respiration?
No, because the electron acceptor is what cates the electrons as the leave the electron transport chain, which is oxygen in aerobic respiration. Since aerobic respiration uses oxygen, and anaerobic fermentation is abest of oxygen, anaerobic fermentation cannot possibly use oxygen as respiration does.
What is the definition of an anaerobic respiration?
Anaerobic respiration is respiration without involving oxygen.It makes use of electron acceptors other than oxygen. Although oxygen is not used as the final electron acceptor, the process still uses a respiratory electron transport chain.Anaerobic respiration is not fermentation (which makes no use of an electron transport chain), which is another anaerobic process by which organisms obtain energy.
How are lactic and alcoholic acid fermentaion similar?
they dont use oxygen as the final acceptor! basically they are anerobic processes
Do anaerobic bacteria use fermentation or respiration?
The bacterium can produce energy for growth by fermentation or respiration. It can respire aerobically using O2 as a final electron acceptor, or it can respire under anaerobic conditions, using NO3 or fumarate as a terminal electron acceptor. E. coli can use glucose or lactose as a sole carbon source for growth, with the metabolic ability to transform the sugar into all the necessary amino acids, vitamins and nucleotides that make up cells.
In what situation does anaerobic take place?
Anaerobic respiration takes place in situations where the body isn't getting enough oxygen.
What two parts of cellular respiration require oxygen?
-Oxidative phosphorylation: oxygen is the final electron acceptor in the electron transport chain, it also breaks apart and combines with 4 hydrogen atoms to form 2 water molecules. -The Citric Acid Cycle occurs only when oxygen is present but it doesn't use oxygen directly.
Why it is necessary for oxygen to be the final electron acceptor in aerobic respiration?
