Anaerobic respiration is a form of respiration using electron acceptors other than oxygen. Although oxygen is not used as the final electron acceptor, the process still uses a respiratory electron transport chain; it is respiration without oxygen. In order for the electron transport chain to function, an exogenous final electron acceptor must be present to allow electrons to pass through the system. In aerobic organisms, this final electron acceptor is oxygen. Molecular oxygen is a highly oxidizing agent and, therefore, is an excellent acceptor. In anaerobes, other less-oxidizing substances such as sulfate (SO42-), nitrate (NO3-), sulfur (S), or fumarate are used. These terminal electron acceptors have smaller reduction potentials than O2, meaning that less energy is released per oxidized molecule. Anaerobic respiration is, therefore, in general energetically less efficient than aerobic respiration(?).
Anaerobic respiration is used mainly by prokaryotes that live in environments devoid of oxygen. Many anaerobic organisms are obligate anaerobes, meaning that they can respire only using anaerobic compounds and will die in the presence of oxygen.
Breathing is the process that moves air in and out of the lungs. Aerobic organisms of these types—such as birds, mammals, and reptiles—require oxygen to release energy via respiration, in the form of the metabolism of energy-rich molecules such as glucose. Breathing is only one process that delivers oxygen to where it is needed in the body and removes carbon dioxide. Another important process involves the movement of blood by the circulatory system. Gas exchange occurs in the pulmonary alveoli by passive diffusion of gases between the alveolar gas and the blood in lung capillaries. Once these dissolved gases are in the blood, the heart powers their flow around the body (via the circulatory system). The medical term for normal relaxed breathing is eupnea.
In addition to removing carbon dioxide, breathing results in loss of water from the body. Exhaled air has a relative humidity of 100% because of water diffusing across the moist surface of breathing passages and alveoli.
What else can I help you with?
How is anaerobic respiration used to make alcohol?
In anaerobic respiration, yeast cells convert sugars into ethanol and carbon dioxide. This process, known as fermentation, is commonly used in the production of alcoholic beverages like beer and wine. The lack of oxygen forces the yeast to produce energy through anaerobic respiration, leading to the formation of alcohol as a byproduct.
Is respiration defined as breathing?
Cellular respiration and breathing are 2 separate things. Breathing is a process of inhaling oxygen into lungs and cellular respiration is a process of burning glucose in presence of oxygen to get energy. Hope this helps
Aerobic respiration anaerobic respiration and fermentation are?
Anaerobic respiration is not the same as fermentation, although it does happen in the absence of oxygen unlike aerobic respiration which is when glucose and oxygen react to create carbon dioxide, water and energy. Basically, aerobic respiration is what animals do to gain energy and it is the opposite of photosynthesis.
Why is respiration is not the same as breathing?
Respiration is the process where cells convert oxygen into energy, while breathing is the physical act of inhaling oxygen-rich air and exhaling carbon dioxide. Respiration encompasses both breathing and the subsequent cellular process that uses oxygen to produce energy in the form of ATP.
What is respiration in humans?
Breathing and Respiration are not the same thing. Breathing is movement of air into and out of the lungs. Respiration is the process in which oxygen and glucose undergo a complex series of chemical reactions inside cells. Hope this helped!
What is the relationship between the processes of breathing and cellular respiration?
Respiration and breathing are the same thing.
Is alveoli used in both respiraton and breathing or only in respiration?
Respiration is a technical word for breathing. it means the same thing.
What do anaerobic and aerobic respiration have that are the same?
Glycolysis
Describe how your cardiovascular and respiratory systems work together?
The words breathing and respiration are often used to mean the same thing. However, breathing is only one part of respiration.
Is breathing the same thing as smelling?
No, breathing and smelling are not the same thing. Breathing is the process of taking air into and out of the lungs to facilitate respiration, while smelling is the process of detecting and recognizing scents using the nose and olfactory system.
Is respiration and breathing same process?
Repiration and Breathing are not the same process. Respiration is converting glucose to useable energy.
Are breathing and respiration the same process?
Breathing and respiration are related but not the same process. Breathing is the physical act of inhaling and exhaling air, while respiration is the chemical process where cells convert oxygen and nutrients into energy.
How are glycolysis and oxidative respiration different?
Glycolysis converts glucose into pyruvate and releases energy to create ATP. Oxidative respiration uses the oxidation of nutrients, or the loss of electrons in the molecule, as the source of energy to make the ATP. Both create the same thing, but the difference lies in the source of the energy.
What are difference between breathing and respiration?
Both are the Same

How does CPR maintain cellular respiration?
CPR maintains cellular respiration the same as in normal breathing and pulse rate. CPR is mechanically breathing and circulating the blood for the victim.
