The pyruvic acid that is produced by glycolysis is used as the initial input for the Krebs Cycle (also called citric acid cycle). In the initial step of the Krebs Cycle, the pyruvic acid is converted to acetyl-CoA via pyruvate decarboxylation. This continues a series of chemical reactions leading to the production of 2 ATP molecules.
What else can I help you with?
Do all microorganisms use pyruvic acid in the same way?
No, not all microorganisms use pyruvic acid in the same way. Pyruvic acid is a key molecule in cellular respiration and can be converted into different compounds depending on the organism and its metabolic pathways. Some microorganisms may further metabolize pyruvic acid through fermentation, while others may oxidize it completely through the citric acid cycle.
What come after glycolysis?
After glycolysis you will go through bridging reaction to the Krebs cycle, also known as the citric acid cycle because of the use of citric acid. the reducing power generated indirectly helps to power oxidative phosphorylation that occurs, which yields a total of 34 ATP's from one glucose molecule. Good luck
How do cells use a high-calorie molecule such as glucose?
the glucose is break down in the cell by 1)glycolysis 2)preparation of pyruvic acid 3) kreb's cycle or citric acid cycle or CAC or tricarboxylic acid cycle 4)oxidative phosphorylation and after that ATP is produced which is the energy currency of our body
Where is NADH or FADH used and produced during microbial metabolism?
NADH and FADH are produced during glycolysis, the citric acid cycle, and the electron transport chain in microbial metabolism. These molecules are used in the electron transport chain to generate ATP through oxidative phosphorylation.
Is ATP produced in both photosynthesis and respiration?
Yes and No. There are two parts of photosynthesis, the light reactions and Calvin cycle. The light reactions produce ATP and NADPH which the Calvin reactions then use to produce sugars. So yes in respration 32-38 ATP are produced. And yes ATP is made by the light rxns in photosynthesis but is not a final product like the ATP in respiration
What is the purpose of the Krebs cycle in a cell?
The purpose of the Krebs Cycle is basically to produce NADH+H and FADH2. Pyruvic acid enters the Krebs Cycle than goes through a series of reactions and the final product is six NADH+H and two FADH2. These energy carriers are than sent to the electron transport chain. The Krebs cycle goes around twice for every molecule.
Do all microorganisms use pyruvic acid in the same way?
No, not all microorganisms use pyruvic acid in the same way. Pyruvic acid is a key molecule in cellular respiration and can be converted into different compounds depending on the organism and its metabolic pathways. Some microorganisms may further metabolize pyruvic acid through fermentation, while others may oxidize it completely through the citric acid cycle.
Are ATP synthases channels for the passage of hydrogen ions?
Yes. Cellular respiration involves three steps: glycolysis, the Krebs Cycle (also called the Citric Acid Cycle) and the Electron Transport Chain. Glycolysis breaks up glucose into two molecules of pyruvic acid, the Krebs Cycle strips away carbon from these pyruvic acids in order to free up electrons, and the Electron Transport Chain takes these electrons and uses oxygen to pull them down a series of proteins, moving hydrogen across the internal membrane of the mitochondria in the process. ATP synthase takes these hydrogen protons as they move back down their concentration gradient and uses them to make ATP.
What come after glycolysis?
After glycolysis you will go through bridging reaction to the Krebs cycle, also known as the citric acid cycle because of the use of citric acid. the reducing power generated indirectly helps to power oxidative phosphorylation that occurs, which yields a total of 34 ATP's from one glucose molecule. Good luck
How does the purpose of the Krebs cycle differ from the purpose of the Calvin cylce?
The Krebs Cycle's purpose is to produce ATP that cells can use, occurs in animal cells. The Calvin Cycle is in chloroplasts and is used to produce glucose for cells. *
How does electron transport chain use the high energy electron from the Krebs cycle?
The electron transport chain uses the high-energy electrons from the Krebs cycle to convert ADP into ATP.
Does the electon transport chain use high energy electons from the Krebs cycle?
No
How does fermentation affect the muscular system?
In muscle cells, form of fermentation takes place. When muscle cells contract too frequently (as in strenuous exercise), they rapidly use up their oxygen supply. As a result, the electron transport system and Krebs cycle slow considerably, and ATP production is slowed. However, muscle cells have the ability to produce a small amount of ATP through glycolysis in the absence of oxygen. The muscle cells convert glucose to pyruvic acid. Then an enzyme in the muscle cells converts the pyruvic acid to lactic acid. Eventually, however, the lactic acid buildup causes intense fatigue, and the muscle cell stops contracting.Cited from:CliffsNotes.com. Fermentation. 1 Mar 2011
Krebs cycle anaerobic or aerobic?
Aerobic. The Krebs cycle is a way of producing ATP using oxygen. The use of oxygen for energy production means Aerobic (as opposed to Anaerobic or without-oxygen).
What are the TOTAL products of the Krebs cycle?
The Krebs cycle, also known as the citric acid cycle, produces a total of three NADH, one FADH2, and one GTP (or ATP) per acetyl-CoA molecule that enters the cycle. Additionally, it releases two molecules of carbon dioxide (CO2) as waste products. This cycle occurs in the mitochondrial matrix and plays a crucial role in cellular respiration by generating high-energy electron carriers for use in the electron transport chain.
What is the purpose of the accounting cycle?
The purpose of accounting is to provide important financial information in order to make fast and precise decisions. The Krebs Cycle's purpose is to produce ATP that cells can use, occurs in animal cells. The Krebs Cycle is in chloroplasts and is used to produce gluclose for cell
