How many moles of ATP are obtained from oxidation of 1 mole of acetyl CoA in the common metabolic pathway?
The oxidation of 1 mole of acetyl CoA in the common metabolic pathway, particularly through the citric acid cycle (Krebs cycle), typically yields 10 moles of ATP. This includes 3 moles of NADH (which produces about 7.5 ATP), 1 mole of FADH2 (which yields about 1.5 ATP), and 1 mole of GTP (equivalent to 1 ATP). Therefore, the total energy yield from one mole of acetyl CoA is approximately 10 ATP.

What stage of cellular respiration do fats proteins and carbohydrates enter the metabolic pathway?
Fats, proteins, and carbohydrates enter the metabolic pathway of cellular respiration during the acetyl-CoA formation stage. Fats and carbohydrates are broken down into acetyl-CoA through different pathways, while proteins are converted into amino acids, which can then enter the acetyl-CoA formation stage.
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 common pathway for oxidation of products of glucose and fatty acids catabolism?
The common pathway for oxidation of products of glucose and fatty acids catabolism is the citric acid cycle (also known as the Krebs cycle). In this cycle, acetyl-CoA derived from both glucose (from glycolysis) and fatty acids (from beta-oxidation) is oxidized to produce NADH and FADH2, which are then used to generate ATP through oxidative phosphorylation in the electron transport chain.
What is an example of an Amphibolic pathway?
The tricarboxylic acid (TCA) cycle is an example of an amphibolic pathway. It is involved in both catabolic and anabolic processes, converting acetyl-CoA into ATP through oxidative metabolism and producing intermediates that serve as precursors for biosynthesis.
What makes acetly coenzyme A?
Acetyl coenzyme A is formed from the breakdown of carbohydrates, fats, and proteins in the cell. These molecules are converted into acetyl CoA through various metabolic pathways such as glycolysis, fatty acid oxidation, and amino acid catabolism. Acetyl CoA then enters the citric acid cycle to generate energy in the form of ATP.
Where does beta-oxidation occur in the cell?
Beta-oxidation occurs in the mitochondria of a cell. It is a metabolic pathway that breaks down fatty acids to generate acetyl-CoA, which can then enter the citric acid cycle to produce energy.

What molecule produces Acetyl-CoA?
Acetyl-CoA is primarily produced from the breakdown of carbohydrates, fats, and proteins. In carbohydrate metabolism, glucose is converted into pyruvate through glycolysis, which is then transformed into Acetyl-CoA via the pyruvate dehydrogenase complex. Additionally, fatty acids undergo beta-oxidation to yield Acetyl-CoA, while certain amino acids can also be converted into Acetyl-CoA through various metabolic pathways.
Fatty acids are metabolized by what pathway?
Beta-oxidation is the major pathway by which fatty acids are metabolized. However, there are other minor pathways for fatty acid metabolized. These include alpha-oxidation (for branched fatty acids) and omega-oxidation.
Where does the Krebs cylce takes place?
The Krebs cycle, also known as the citric acid cycle, takes place in the matrix of the mitochondria in eukaryotic cells. This multi-step metabolic pathway is responsible for the production of energy in the form of ATP through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins.
How does beta-oxidation function in lipid catabolism?
Beta-oxidation is a process that breaks down fatty acids into acetyl-CoA molecules, which can then enter the citric acid cycle to produce energy in the form of ATP. This process involves a series of enzymatic steps that sequentially removes two-carbon units from the fatty acid chain, generating acetyl-CoA molecules. Beta-oxidation is a key pathway in lipid catabolism, allowing the body to utilize stored fat as an energy source.
Where is the citric cycle located?
The citric acid cycle, also known as the Krebs cycle, takes place in the mitochondria of eukaryotic cells. It is a central metabolic pathway involved in generating energy in the form of adenosine triphosphate (ATP) through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins.
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.
