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 is the fate of pyruvate in mitochondrial respiration?
Pyruvate is converted into acetyl-CoA in the mitochondrial matrix through the process of pyruvate oxidation. Acetyl-CoA then enters the citric acid cycle to produce reducing equivalents (NADH and FADH2) and ATP through oxidative phosphorylation.
What happens during anaerobic respiration?
During anaerobic respiration, cells produce energy without the presence of oxygen. The process begins with glycolysis, where glucose is broken down into pyruvate. In the absence of oxygen, pyruvate is converted into either lactic acid in animals or alcohol and carbon dioxide in yeast and some bacteria, generating a small amount of ATP.
What are the reactants and products for cellular respiration anaerobic?
The reactants for anaerobic cellular respiration are glucose molecules, which are broken down into pyruvate molecules. The end products of anaerobic respiration in animals is lactic acid, while in certain bacteria and yeast, the end product is ethanol and carbon dioxide.
What is the purpose of the fermentation reactions after glycolysis?
The purpose of fermentation reactions after glycolysis is to regenerate NAD+ so that glycolysis can continue producing ATP in the absence of oxygen. Fermentation allows for the conversion of pyruvate into different end products (such as lactate or ethanol) to maintain cellular energy production in anaerobic conditions.
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 are the five compounds associated with anaerobic respiration?
The five compounds associated with anaerobic respiration are glucose (substrate), pyruvate (end product of glycolysis), lactate (end product in animals), ethanol (end product in yeast), and ATP (energy currency produced).
What steps in the breakdown of glucose does not require oxygen?
The breakdown of glucose that does not require oxygen is known as anaerobic respiration or fermentation. This process primarily includes glycolysis, where one molecule of glucose is converted into two molecules of pyruvate, producing a small amount of ATP and NADH. In the absence of oxygen, pyruvate can then be further converted into lactate (in animals) or ethanol and carbon dioxide (in yeast). These steps allow cells to generate energy without the use of oxygen.
What happens during anaerobic respiration?
During anaerobic respiration, cells produce energy without the presence of oxygen. The process begins with glycolysis, where glucose is broken down into pyruvate. In the absence of oxygen, pyruvate is converted into either lactic acid in animals or alcohol and carbon dioxide in yeast and some bacteria, generating a small amount of ATP.
What processes does anaerobic respiration involve?
Anaerobic respiration involves the breakdown of glucose without the presence of oxygen, resulting in the production of energy. In this process, glucose is converted into pyruvate through glycolysis, and then further processed into either lactic acid in animals or ethanol and carbon dioxide in yeast and some bacteria. This process yields fewer ATP molecules compared to aerobic respiration. Anaerobic respiration is crucial for organisms in oxygen-depleted environments or during intense exercise when oxygen supply is limited.
What are the reactants and products for cellular respiration anaerobic?
The reactants for anaerobic cellular respiration are glucose molecules, which are broken down into pyruvate molecules. The end products of anaerobic respiration in animals is lactic acid, while in certain bacteria and yeast, the end product is ethanol and carbon dioxide.
Explain the process of breakdown of glucose in a cell you in the presence of o2ii in the absence of o2?
In the presence of oxygen (aerobic respiration), glucose undergoes glycolysis in the cytoplasm, producing pyruvate, which is then transported into the mitochondria for the Krebs cycle and oxidative phosphorylation, yielding a high amount of ATP. In the absence of oxygen (anaerobic respiration), glycolysis still occurs, but pyruvate is converted into lactic acid in animals or ethanol and carbon dioxide in yeast, resulting in significantly less ATP production. Both processes begin with glycolysis, but the fate of pyruvate and the efficiency of ATP generation differ markedly.
What is the purpose of the fermentation reactions after glycolysis?
The purpose of fermentation reactions after glycolysis is to regenerate NAD+ so that glycolysis can continue producing ATP in the absence of oxygen. Fermentation allows for the conversion of pyruvate into different end products (such as lactate or ethanol) to maintain cellular energy production in anaerobic conditions.
What do anaerobic animals not need to survive?
Anaerobic animals (and other substances) survive without 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.
