Which of the following statements about beta oxidation is false?
A
Beta oxidation directly produces ATP as one of its products.
B
Beta oxidation requires the initial activation of fatty acids by Coenzyme A.
C
Beta oxidation involves the breakdown of fatty acids into acetyl-CoA units.
D
Beta oxidation occurs in the mitochondria of cells.
Verified step by step guidance1
Understand the process of beta oxidation: Beta oxidation is a metabolic pathway that involves the breakdown of fatty acids into acetyl-CoA units. This process is crucial for energy production in cells.
Identify the location of beta oxidation: Beta oxidation occurs in the mitochondria of cells, where fatty acids are broken down to generate acetyl-CoA, which enters the citric acid cycle.
Examine the role of Coenzyme A: Before beta oxidation can proceed, fatty acids must be activated by Coenzyme A. This activation forms acyl-CoA, which is necessary for the subsequent steps of beta oxidation.
Clarify the products of beta oxidation: Beta oxidation itself does not directly produce ATP. Instead, it generates acetyl-CoA, NADH, and FADH2, which are used in other metabolic pathways to produce ATP.
Evaluate the statements: Based on the understanding of beta oxidation, identify the false statement. The statement that beta oxidation directly produces ATP is false, as ATP is produced indirectly through subsequent pathways.
