How is acetyl CoA converted into ketone bodies?
Acetyl CoA is converted into ketone bodies through a process called ketogenesis, which occurs in the liver. During this process, acetyl CoA molecules are condensed to form acetoacetyl CoA, which is then converted into ketone bodies such as acetoacetate and beta-hydroxybutyrate. These ketone bodies can be used as an alternative fuel source by the body, particularly during times of fasting or low carbohydrate intake.
Can acetyl CoA be converted to glucose in the body?
No, acetyl CoA cannot be directly converted to glucose in the body.
What is the possible fate of acetyl CoA in cellular metabolism?
Acetyl CoA can be used in cellular metabolism to produce energy through the citric acid cycle or to synthesize fatty acids. It can also be converted into ketone bodies in times of fasting or low carbohydrate intake.
What happens to acetyl CoA if its not needed in the Krebs cycle?
Acetyl CoA is multifunctional; it can be used to produce fat or ATP. If the body needs energy, acetyl CoA enters the Krebs cycle. If the body doesn't need energy, acetyl CoA is channelled into an anabolic pathway that synthesizes lipids as a way of storing large amounts of energy as fat.
What is the name of the molecule that pyruvates are changed into during pyruvates processing?
Acetyl CoA

Which molecule can be made from acetyl CoA molecules?
Fatty acids, cholesterol, and ketone bodies can be made from acetyl CoA molecules.
Can acetyl CoA be converted to glucose in the body?
No, acetyl CoA cannot be directly converted to glucose in the body.
Location of Acetyl CoA in a cell?
Acetyl CoA is generated in the mitochondrial matrix through the breakdown of carbohydrates, fats, and proteins. It plays a central role in energy production in the form of ATP through the citric acid cycle. Acetyl CoA is also a key intermediate in fatty acid synthesis, cholesterol synthesis, and the production of ketone bodies.

Acetyl CoA
What compound enters the Krebs cycle and is made from the last compound?
Acetyl CoA is the compound that enters the Kreb's cycle.
What are the products of acetyl CoA formation from a molecule of pyruvate?
The products of acetyl CoA formation from a molecule of pyruvate are acetyl CoA, NADH, and carbon dioxide. This process occurs during the mitochondrial pyruvate dehydrogenase complex reaction, where pyruvate is converted to acetyl CoA by a series of enzymatic reactions.
Can acetyl CoA be used to produce glucose?
No, acetyl CoA cannot be directly used to produce glucose.
In the liver when ATP is not needed excess acetyl CoA molecules formed from fatty acid breakdown are often metabolized to?
Excess acetyl CoA molecules formed from fatty acid breakdown in the liver are often metabolized to ketone bodies such as acetoacetate, β-hydroxybutyrate, and acetone in a process called ketogenesis. These ketone bodies can then be used as alternative fuel sources by tissues like the brain and muscles when glucose availability is low, such as during fasting or prolonged exercise.
Why does ketogenesis occur?
Ketogenesis is a metabolic process to form ketone bodies in mitochondrial matrix of hepatocytes in emergency condition from accumulated Acetyl-CoAobtained from increased incomplete fatty acid oxidation due to cellular glucose deprivation.CoA is a complex structure which is impermeable to mitochondrial membranes, Acetate linked to CoA as AcetylCoA is also impermeable.The steps of Ketogenesis occur to remove the CoA from the molecules of AcetylCoA and form a permeable ketone body Acetoacetate( Primary Ketone body).Acetoacetate then spontaneously decarboxylated to stable Acetone and reduced to Beta Hydroxy Butyrate (Secondary ketone bodies).Thus Ketogenesis occur to remove the accumulated impermeable Acetyl-CoA from mitochondrial matrix by forming permeable ketonebodies.Ketogenesis removes the acetate carbon out of matrix and maintain the CoA pool of matrix.
