Acetyl-CoA is produced in the mitochondria by a process called oxidative decarboxylation. This process involves the removal of a carboxyl group from a molecule of pyruvate, which is a product of glucose metabolism, and the conversion of the pyruvate into acetyl-CoA.

How is CoA synthesized?
CoA is synthesized by the condensation of pantothenate with cysteamine.
How is acetyl CoA formed after glycolysis?
Acetyl CoA is formed when the two-carbonaldehyde group from pyruvate is combined with coenzyme A.
How does pyruvate become acetyl-CoA?
Pyruvate is decarboxylated by pyruvate dehydrogenase and becomes acetaldehyde. Acetaldehyde is then reduced by NADH to acetyl-CoA.
Is acetyl-CoA formed in the mitochondria?
Yes, acetyl-CoA is formed in the mitochondria.
What is the role of acetyl coenzyme A?
A key role of acetyl-CoA is to deliver the acetyl group to the citric acid cycle (Krebs cycle) to be oxidized for energy production.
Which can produce Acetyl-CoA quizlet?
Fatty acids and glucose
What vitamin is coenzyme A derived from?
Coenzyme A is derived from vitamin B5.
What is Acetyl-CoA how is it made?
Acetyl-CoA is a molecule that is involved in the Krebs Cycle, and it is made when enzymes attach a two-carbon acetyl group to coenzyme A.
What Acetyl-CoA means?
Acetyl-CoA is an intermediate in the metabolism of glucose. It is formed by the action of enzymes in the cell’s mitochondria, and is used in the production of energy in the Krebs cycle.
Where does Acetyl-CoA formation?
Acetyl-CoA is formed in the mitochondria via the pyruvate dehydrogenase complex.
How is acetyl-CoA formed what is its role in citric acid cycle?
Acetyl-CoA is formed by the breakdown of glucose and fatty acids. It is a key molecule in the citric acid cycle, which is a key process in the production of energy in cells.
What happens when pyruvate is converted to Acetyl-CoA quizlet?
Acetyl-CoA is then used in the Krebs cycle to produce ATP.
What are the 4 steps of fatty acid synthesis?
1. Synthesis of malonyl-CoA from acetyl-CoA
2. Addition of malonyl-CoA to acetyl-CoA to form malonic ester
3. Reduction of malonic ester to form crotonic ester
4. Dehydration of crotonic ester to form butyryl-CoA
How are fatty acids synthesized?
Fatty acids are synthesized from acetyl-CoA.
How is acetyl-CoA transported into the cytosol for fatty acid synthesis to begin?
A membrane protein called carnitine acyltransferase I (CATI) translocates acetyl-CoA into the cytosol.
