How many acetyl-CoA molecules are formed from the metabolic breakdown of palmitic acid?

8 acetyl-CoA molecules
Similar to how 8 acetyl-CoA molecules are required to produce palmitic acid, a 16-carbon fatty acid, the breakdown of palmitic acid will produce 8 acetyl-CoA molecules.

What process breaks down fatty acids into acetyl-CoA?

Fatty acid oxidation is the mitochondrial aerobic process of breaking down a fatty acid into acetyl-CoA units.

How many acetyl-CoA molecules can be produced from palmitic acid?

Palmitic acid is the most common type of fatty acid that contains sixteen carbon atoms and no carbon-carbon double bonds. In order to completely break down the fatty acid, a total of seven cycles of beta oxidation must take place. This generates a total of 8 acetyl-CoA molecules, 7 NADH molecules and 7 FADH2 molecules.

How many acetyl-CoA creates after oxidation of palmitate?

Oxidation of of palmitic acid yields 7 NADH + 7 FADH2 + 8 acetyl-CoA in 7 cycles of mitochondrial beta oxidation. Every acetyl-CoA yields 3 NADH + 1 FADH2 + 1 GTP (=ATP) during Krebs cycle.

How many molecules of acetyl-CoA are created from a 14 carbon fatty acid?

7 molecules of acetyl-CoA.

Can fatty acids be converted to acetyl-CoA?

Fatty acids are broken down to acetyl-CoA by means of beta oxidation inside the mitochondria, whereas fatty acids are synthesized from acetyl-CoA outside the mitochondria, in the cytosol.

How do you make acetyl-CoA?

Acetyl-CoA is generated either by oxidative decarboxylation of pyruvate from glycolysis, which occurs in mitochondrial matrix, by oxidation of long-chain fatty acids, or by oxidative degradation of certain amino acids. Acetyl-CoA then enters in the TCA cycle where it is oxidized for energy production.

How many molecules of acetyl-CoA are produced from the complete oxidation of stearic acid?

Stearic acid is an 18-carbon saturated fatty acid. It will undergo 8 rounds of beta-oxidation to produce 9 Acetyl CoA…

How many ATP can be generated from the β-oxidation of palmitoleic acid?

The NADH and FADH2 produced by both beta oxidation and the TCA cycle are used by the mitochondrial electron transport chain to produce ATP. Complete oxidation of one palmitate molecule (fatty acid containing 16 carbons) generates 129 ATP molecules.

How many molecules of acetyl-CoA will be produced from the complete beta oxidation of a c14 fatty acid?

The long-chain acyl-CoA enters the fatty acid β-oxidation pathway, which results in the production of one acetyl-CoA from each cycle of fatty acid β-oxidation.

How is acetyl-CoA synthesized?

Acetyl-CoA is synthesized in mitochondria by a number of reactions: oxidative decarboxylation of pyruvate; catabolism of some amino acids (e.g., phenylalanine, tyrosine, leucine, lysine, and tryptophan); and β-oxidation of fatty acids (see earlier).
