What sequence best summarizes lactic acid fermentation?
Glucose is broken down into pyruvate during glycolysis. Pyruvate is then converted to lactic acid in the absence of oxygen, regenerating NAD+ for glycolysis to continue.
How is glucose broken down in anaerobic respiration?
In anaerobic respiration, glucose is partially broken down into pyruvate through glycolysis. Pyruvate is then converted into lactic acid in animals or ethanol in microorganisms, with no oxygen required for this process. This allows for the production of ATP in the absence of oxygen.
What is is the order of the steps for cellular respiration?
1. Glucose is metabolised to form pyruvate (glycolysis) Anaerobic (without oxygen): - Pyruvate is converted to lactate or ethanol Aerobic (in the presence of oxygen): - Pyruvate is converted to acetyl CoA - Citric Acid Cycle - Electron transport chain
What is converted into lactic acid?
During energy production without oxygen, glucose is converted into lactic acid through a process called anaerobic glycolysis. This occurs in muscle cells during intense exercise when oxygen supply is limited.
What two processes in glucose breakdown are anaerobic?
During glucose breakdown, glycolysis and fermentation occur anaerobically. Glycolysis breaks a glucose molecule into energy and pyruvate. Fermentation uses to the pyruvate to form either ethanol or lactate.
The process in which glucose is converted to pyruvate?
glycolysisNote:Glycolysis, or the splitting of sugar, splits a six-carbon glucose into two three-carbon pyruvate molecules.It is called glycolosis

What is pyruvate converted into when oxygen is not present?
lactate

During glycolosys glucose molecules is broken into?
In glycolysis, one 6-carbon glucose molecule is converted into two 3-carbon pyruvate molecules. If no oxygen is present then each of those two pyruvate molecules will be converted into 3-carbon lactate (lactic acid).

During the anaerobic phase of respiration glucose is changed to?
During the anaerobic phase of respiration, glucose is converted into pyruvate through a process called glycolysis. This process does not require oxygen and occurs in the cytoplasm of the cell. If oxygen is not present, pyruvate can then be further converted into lactic acid (in animals) or ethanol and carbon dioxide (in some microorganisms) to generate a small amount of ATP.
What are the stages of Cellular respiration.?
The Stages of Cellular Respiration 1. Glucose is converted to pyruvate producing a small amount of ATP and NADH. 2. When oxygen is present, pyruvate and NADH are used to make a large amount of ATP. When oxygen isn't present, pyruvate is converted to either lactate or ethanol and carbon dioxide. In Stage One, the breakdown of glucose happens, with glycolysis. In Stage Two, ATP is produced. Stage one is called the Calvin cycle, and stage two is called the Krebs cycle. For more information, go to http://Biology.about.com/od/cellularprocesses/a/cellrespiration.htm
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.
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.
