Final answer:
In the complete beta oxidation of an eight-carbon fatty acid, four acetyl-CoA molecules and one propionyl-CoA molecule are produced.
Step-by-step explanation:
The complete beta oxidation of an eight-carbon fatty acid would involve four cycles of beta oxidation. Each cycle of beta oxidation produces one acetyl-CoA molecule, therefore, four acetyl-CoA molecules would be produced. Additionally, the last cycle of beta oxidation also produces one propionyl-CoA molecule. So, in the complete beta oxidation of one eight-carbon fatty acid, four acetyl-CoA molecules and one propionyl-CoA molecule would be produced.
