In humans, under ANAEROBIC conditions (no O2), pyruvate is 'converted' to lactate, though I wouldn't say it is "broken down".
In humans, under AEROBIC conditions (O2 present), pyruvate is converted to Acetyl-CoA, via the pyruvate dehydrogenase reaction.
In yeast, pyruvate is converted into ethanol (Party Fluid) via pyruvate decarboxylase and then alcohol dehydrogenase.

What happens to pyruvate when there is no oxygen?
During anaerobic conditions, pyruvate is converted to lactic acid or ethanol via fermentation pathways to regenerate NAD+ for glycolysis to continue. This process does not produce additional ATP and is less efficient than aerobic respiration.
What happens after glycolosis if there is no oxygen available?
If there is no oxygen available after glycolysis, anaerobic respiration occurs. This process involves the conversion of pyruvate into lactic acid (in animals) or ethanol (in yeast and some bacteria) to regenerate NAD+ and continue ATP production. Anaerobic respiration is less efficient than aerobic respiration in terms of ATP production.
What happens when oxygen is not present to brakedown glucose?
When oxygen is not present to break down glucose through aerobic respiration, the process shifts to anaerobic respiration (fermentation) to continue producing energy. This results in the incomplete breakdown of glucose, leading to the production of lactic acid in animals or ethanol in plants and some microorganisms. This process is less efficient in terms of energy production compared to aerobic respiration.
Explain what happens to the process when oxygen runs out?
When oxygen runs out, aerobic processes like cellular respiration cannot continue. This leads to a shift towards anaerobic processes, which are less efficient at producing energy. Inadequate oxygen can result in the buildup of lactic acid and eventually cell death.
What happens when Pyruvate reacts with dinitrophenylhydrazine in SGOT?
Pyruvate reacts with dinitrophenylhydrazine in the presence of the enzyme SGOT to form a yellow/orange precipitate. This reaction is used in laboratory tests to measure SGOT activity levels, as the formation of the precipitate indicates the presence of pyruvate as a substrate for SGOT.
What happens to pyruvate when there is no oxygen?
During anaerobic conditions, pyruvate is converted to lactic acid or ethanol via fermentation pathways to regenerate NAD+ for glycolysis to continue. This process does not produce additional ATP and is less efficient than aerobic respiration.
What happens to anaerobic by-products?
Anaerobic by-products, such as lactic acid or ethanol, can be further metabolized in processes like fermentation or converted into other substances by other biochemical pathways. In the case of lactic acid, it can be converted back to pyruvate and metabolized in aerobic conditions. Ethanol produced during anaerobic fermentation can be used in various industrial processes or as a biofuel.
What happens in glycolisis?
Glucose is converted into pyruvate.It is common to aerobic and non aerobic erspiration.Glucose is splited and converted into pyruvate..It is common to aerobic and non aerobic respiration.
What is the difference between respiration and fermentation?
Cellular respiration:it's what happens under aerobic conditions. Which simply means when oxygen is present.Fermentation: Fermentation on the other hand is what happened and anaerobic conditions (when oxygen is not present).
What is the difference cellular respiration and fermentation?
Cellular respiration:it's what happens under aerobic conditions. Which simply means when oxygen is present.Fermentation: Fermentation on the other hand is what happened and anaerobic conditions (when oxygen is not present).
What happens to aerobic and anaerobic enzymes?
Aerobic enzymes function in the presence of oxygen to catalyze reactions involved in aerobic respiration, while anaerobic enzymes function in the absence of oxygen or low oxygen conditions. Aerobic enzymes support the breakdown of glucose to produce ATP efficiently through the electron transport chain, while anaerobic enzymes help produce ATP through processes like fermentation in the absence of oxygen.
What happens after glycolosis if there is no oxygen available?
If there is no oxygen available after glycolysis, anaerobic respiration occurs. This process involves the conversion of pyruvate into lactic acid (in animals) or ethanol (in yeast and some bacteria) to regenerate NAD+ and continue ATP production. Anaerobic respiration is less efficient than aerobic respiration in terms of ATP production.
What happens to pyruvate during alcohol fermentation?
During alcohol fermentation, pyruvate, produced from glycolysis, is converted into ethanol and carbon dioxide. This process occurs in anaerobic conditions, where the pyruvate is first decarboxylated to form acetaldehyde, which is then reduced to ethanol by the enzyme alcohol dehydrogenase. This conversion regenerates NAD+, allowing glycolysis to continue and produce ATP in the absence of oxygen.
What happens to pyruvate produced when very little oxygen is available?
Pyruvate is the result of glycolysis, the degradation of a molecule of glucose. In aerobic conditions (with O2 present), pyruvate is oxidized to H2O and CO2 via the citric acid cycle and oxidative phosphorylation to produce energy (ATP). In anaerobic conditions (low levels of O2), pyruvate metabolism goes in two directions: in yeasts, an alcoholic fermentation takes place (with the production of two CO2 molecules + two molecules of ethanol); while in muscle, homolactic fermentation occurs (with the result of 2 molecules of lactate).
What happens when an aerobic organisms is placed in an anaerobic?
the electron transport chain stops stoping the citric acid cycle
What is the site of anaerobic respiration?
In fast twitch muscles.Aerobic respiration occurs in the mitochondria.
What is the difference between aerobic and anarobic celluar respiration?
Aerobic respiration is when there is enough oxygen to use by the muscles. This happpens in long distance running. Anaerobic respiration is when respiration continues without sufficient oxygen,This happens more often in sprinting. Anaerobic respiration forces the muscles to rip and repair more often, and become bigger and more efficient. This is why sprinters like Christine Ohuruogu tend to be more muscular than marathon runners such as Paula Radcliffe.
