A strategy that is employed in a variety of biochemical pathways involves investing energy early on and reaping a large energy payoff at the end. Which of the following statements demonstrates its application in fat catabolism?

• A. The formation of glycerol occurs simultaneously with the conversion of ATP to AMP and pyrophosphate. This energy expenditure is recovered through lipogenesis.
• B. The breakdown of fatty acids activates the conversion of AMP to ATP and pyrophosphate. This provides energy for the hydrolysis of triacylglycerols.
• C. The formation of a fatty acyl-CoA occurs simultaneously with the conversion of ATP to AMP and pyrophosphate. This energy expenditure is recovered through the β oxidation of fatty acids.
• D. The breakdown of triglycerides activates the conversion of AMP to ATP and pyrophosphate. This provides energy for the storage of fatty acids.
