How many acetyl CoA molecules may be obtained from oxidation of a 16-carbon fatty acid?
A fatty acid that contains 20 carbons will yield 10 molecules of acetyl-CoA. Acetyl-CoA is also referred to as acetyl coenzyme A.
What is the energy production from the complete oxidation of a single hypothetical 140-C FFA?
The complete oxidation of a 140-carbon fatty acid (FFA) involves β-oxidation followed by the citric acid cycle and oxidative phosphorylation. Each cycle of β-oxidation produces one molecule of acetyl-CoA, ultimately yielding a significant amount of ATP through the complete oxidation of these acetyl-CoA units. A rough estimate suggests that the total energy yield from the complete oxidation of a 140-carbon FFA can be around 900-1,000 ATP molecules, depending on the specific metabolic pathways and the efficiency of the electron transport chain.
Beta oxidation of these molecules converts them into acetyl-coa which can then enter the Krebs cycle for energy derivation these are?
answer is fatty acids (I had the exact same question in my Ap Test)
How many molecules of acetyl-CoA are produced in the catabolism of one molecule of stearic acid?
9
Is beta oxidation anabolic or catabolic?
Beta oxidation is a catabolic process. It involves the breakdown of fatty acids into acetyl-CoA molecules, which can be used as an energy source through the citric acid cycle.
Calculate the number of acetyl-SCoA molecules generated by complete B-oxidation of a 12-carbon activated fatty acid?
The answer is 5. An acetyl group (containing two C atoms) is split off the original fatty acyl-SCoA with each repetition of the beta-oxidation spiral. Therefore, the first repetition of the beta-oxidation yields one acetyl-SCoA molecule and a fatty acyl-SCoA molecule that is two carbon atoms shorter than the initial fatty acyl-SCoA. There will be five acetyl-SCoA molecules produced by the fifth repetition.

Acetyl-CoA is produced from?
Acetyl-CoA is produced from the oxidation of pyruvate in the mitochondria during the process of aerobic respiration. Pyruvate is first converted to acetyl-CoA by the pyruvate dehydrogenase complex, which involves a series of enzymatic reactions. Acetyl-CoA is a key molecule that enters the citric acid cycle to generate ATP through the electron transport chain.
What are fatty acids converted to in Beta-oxidation?
Fatty acids are converted into acetyl-CoA molecules during beta-oxidation. Acetyl-CoA is a crucial molecule in the citric acid cycle (Krebs cycle) which generates energy through the production of ATP.

What is produced by fatty acid oxidation?
Fatty acid oxidation produces energy in the form of ATP, as well as acetyl-CoA molecules which can enter the citric acid cycle to generate more ATP through oxidative phosphorylation. Additionally, the oxidation process generates carbon dioxide and water as byproducts.
Is the formation of acetyl CoA aerobic or anaerobic?
The formation of acetyl CoA can occur through both aerobic and anaerobic pathways. In aerobic conditions, acetyl CoA is produced during the breakdown of glucose in the mitochondria. In anaerobic conditions, acetyl CoA can be derived from other molecules like fatty acids or amino acids through processes like beta-oxidation or deamination.

How many ATP molecules are produced from beta oxidation of arachidic acid?
20 ATP from 8 NADH 12 ATP from 12 FADH2 9 acetyl co-A --> 9 GTP, 67,5 ATP from 27 NADH, 13,5 ATP from 9 FADH2 minus 2 ATP to start beta-oxidation = 120 ATP

In aerobic respiration glucose molecules are converted into acetyle CoA molecules when they enter?
In aerobic respiration, glucose molecules are converted into acetyl CoA during a process called pyruvate oxidation. After glycolysis, which occurs in the cytoplasm, glucose is broken down into two molecules of pyruvate. These pyruvate molecules then enter the mitochondria, where they undergo decarboxylation, releasing carbon dioxide and forming acetyl CoA. This acetyl CoA then enters the Krebs cycle, where it plays a crucial role in energy production.
