Fill in the blanks below (input numbers only!) about the metabolism of hexanoic acid, a fatty acid that is one of the components of vanilla, and whose formula is CH3(CH2)4COOH: First, the fatty acid is activated by attaching CoA, which costs ATP molecules. The fatty acid is then broken down through a beta-oxidation spiral, to make acetyl CoA molecules. This will require "turns" of the beta-oxidation process. Since each turn of the cycle yields ATP molecules, and each acetyl COA will yield ATP molecules by going through the rest of its metabolism, the net ATP molecules produced from one molecule of this fatty acid will be
