A fermentation pathway is one of the paths that cellular respiration can take. Cellular respiration that uses oxygen is aerobic and thus completely breaks down glucose using the Kreb's cycle, electon transport chain, and ATP synthetase. Cellular respiration that does not use oxygen is anaerobic and has two possibilities in cells.....1.) the production of lactic acid as in the human body or 2.) fermentation as in bacteria. This can be used to make a variety of alcoholic products, cheese, bread...as in yeast, and a variety of other food products. Glucose begins to break down and ceases to break down any further than a 3 carbon chain....2 of them actually.
What else can I help you with?
What respiration pathway do glycolysis products enter if no oxygen is present in cells?
In the absence of oxygen, the products of glycolysis enter anaerobic pathways such as fermentation. This allows for the regeneration of NAD+ so that glycolysis can continue to produce ATP. Two common types of fermentation are lactic acid fermentation and alcoholic fermentation.
Which metabolic pathway is common to both cellular respiration and fermentation?
The glycolytic pathway is common to both fermentation and cellular respiration. During the course of the metabolic pathway, glucose is broken down to pyruvate. In the presence of oxygen, the pyruvate molecule becomes involved in the TCA cycle. In the absence of oxygen however, fermentation occures. The process is brought about by an enzyme called alcohol dehydrogenase.
If yeast breaks down glucose by the anaerobic pathway the pyruvate is changed to what?
Pyruvate is changed to ethanol and carbon dioxide through fermentation in the anaerobic pathway in yeast.
What is the value of the alcoholic fermentation pathway?
Alcoholic fermentation is valuable for producing alcoholic beverages such as beer and wine. It is also used in baking to make bread rise. Additionally, it is a crucial metabolic pathway for certain microorganisms to generate energy in the absence of oxygen.
Can fermentation in yeast create lactic acid?
No, fermentation in yeast primarily produces ethanol and carbon dioxide through alcoholic fermentation. Lactic acid is produced during lactic acid fermentation, which occurs in certain bacteria and animal cells, not in yeast. While some yeasts can produce small amounts of lactic acid under specific conditions, it is not their primary fermentation pathway.
When an organic product such as pyruvic acid is the final electron acceptor in the metabolic pathway the pathway is termed?
The pathway is termed fermentation. In fermentation, organic products like pyruvic acid accept electrons in order to regenerate NAD+ from NADH, allowing glycolysis to continue in the absence of oxygen.
What respiration pathway do glycolysis products enter if no oxygen is present in cells?
In the absence of oxygen, the products of glycolysis enter anaerobic pathways such as fermentation. This allows for the regeneration of NAD+ so that glycolysis can continue to produce ATP. Two common types of fermentation are lactic acid fermentation and alcoholic fermentation.

1 The anaerobic pathway that follows glycolysis in the absence of oxygen is fermentation -- True or false?
True. Fermentation is the anaerobic pathway that follows glycolysis in the absence of oxygen, allowing for the regeneration of NAD+ to continue glycolysis.
How does fer-mention allow glycolysis to continue?
Glycolysis is followed by a different pathway. The combined process of pathway and glycolysis is called fermentation.
What pathway is used to make energy when no oxygen is present?
Fermentation other wise known as anaerobic.
If yeast breaks down glucose by the anaerobic pathway the pyruvate is changed to what?
Pyruvate is changed to ethanol and carbon dioxide through fermentation in the anaerobic pathway in yeast.
How does NaF effect Fermentation?
NaF (sodium fluoride) can inhibit the process of fermentation by interfering with enzymes involved in glycolysis, a key metabolic pathway in fermentation. It can disrupt the activity of enzymes such as enolase and ATPase, which are crucial for the breakdown of glucose into pyruvate. As a result, NaF can slow down or inhibit the fermentation process.

Can you tell which metabolic pathway is taking place resulting in the formation of carbon dioxide which gives puffed appearance of dough?
The metabolic pathway taking place in this scenario is fermentation, specifically yeast fermentation. During fermentation, yeast consumes sugars present in the dough and produces carbon dioxide as a byproduct. The carbon dioxide gas gets trapped within the dough, causing it to rise and give a puffed appearance when baked.
What is the end products of glucose fermentation?
The end products of glucose fermentation vary depending on the type of organism and the fermentation pathway. In yeast, such as Saccharomyces cerevisiae, glucose fermentation primarily produces ethanol and carbon dioxide. In lactic acid bacteria, glucose fermentation results in lactic acid as the main product. Other fermentation pathways can produce acetic acid, butyric acid, or other organic compounds, depending on the specific microorganisms involved.
