Here are the essential concepts you must grasp in order to answer the question correctly.
Fatty Acids
Fatty acids are carboxylic acids with long hydrocarbon chains, which can be saturated or unsaturated. Saturated fatty acids, like capric acid, contain no double bonds between carbon atoms, resulting in a straight chain structure. This characteristic influences their physical properties and metabolic pathways, including their activation for β-oxidation.

β-Oxidation
β-Oxidation is the metabolic process by which fatty acids are broken down in the mitochondria to generate acetyl-CoA, which can then enter the citric acid cycle for energy production. This process involves the sequential removal of two-carbon units from the fatty acid chain, starting from the carboxyl end, and requires the activation of the fatty acid to acyl-CoA before it can enter the mitochondria.
Fatty Acyl-CoA Activation
The activation of fatty acids to fatty acyl-CoA is a crucial step for their metabolism. This process involves the conversion of a fatty acid into its CoA derivative, catalyzed by the enzyme acyl-CoA synthetase. This activation is essential for the fatty acid to be transported into the mitochondria and undergo β-oxidation, making it a key step in fatty acid metabolism.
