When oxygen is available pyruvate enters the what?
When oxygen is available, pyruvate enters the mitochondria to undergo aerobic respiration. In the mitochondria, pyruvate is converted into acetyl-CoA in the presence of oxygen, leading to the production of ATP through the Krebs cycle and oxidative phosphorylation.
What happen to pyruvate when absent of oxygen?
In the absence of oxygen, pyruvate is converted into lactate through a process called fermentation. This allows for the regeneration of NAD+ so that glycolysis can continue to produce ATP in the absence of oxygen.
What happens after glycolysis if oxygen is available?
If oxygen is available, the pyruvate produced during glycolysis enters the mitochondria and undergoes aerobic respiration. In the presence of oxygen, pyruvate is converted to acetyl CoA, which enters the citric acid cycle to generate more ATP through oxidative phosphorylation. This process enables the efficient extraction of energy from glucose molecules.
What is glycolysis when oxygen is available?
Glycolysis, in the presence of oxygen, is the first stage of cellular respiration where glucose is broken down into pyruvate. This process occurs in the cytoplasm of the cell and produces a small amount of ATP and NADH. The pyruvate then enters the citric acid cycle to further extract energy from it.
Where does pyruvate processing occur?
Pyruvate processing occurs in the mitochondria of eukaryotic cells. It is an important step in cellular respiration where pyruvate is converted to acetyl-CoA before entering the citric acid cycle to generate ATP.
What happens to pyruvate molecules formed glycolysis in the absence of oxygen?
they will enter the Krebs cycle
Muscle cells when an individual is excerising heavily and when the muscle becomes oxygen deprived convert pyruvate to lactate What happens to the lactate in the skeletal muscle cells?
The lactate is taken to the liver and converted back to pyruvate.
When oxygen is available pyruvate enters the what?
When oxygen is available, pyruvate enters the mitochondria to undergo aerobic respiration. In the mitochondria, pyruvate is converted into acetyl-CoA in the presence of oxygen, leading to the production of ATP through the Krebs cycle and oxidative phosphorylation.
Glycolysis produces pyruvate. The fate of this pyruvate depends mainly on the availability of which of the following?
Molecular oxygen
What is pyruvate converted into when oxygen is not present?
lactate
What happen to pyruvate when absent of oxygen?
In the absence of oxygen, pyruvate is converted into lactate through a process called fermentation. This allows for the regeneration of NAD+ so that glycolysis can continue to produce ATP in the absence of oxygen.
How many C atoms are in a molecule of pyruvate?
There are three carbon atoms and three oxygen atoms in each pyruvate molecule.
When oxygen is plentiful pyruvate from glucose is converted to?
acetyl CoA
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 immediately after pyruvate is into the mitochondrion?
Acetyl CoA forms.
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 during glycolsis in cellular respiration?
glucose is changed into pyruvate
