Heading 1 Editing ont Paragraph Styles 10. Triglycerides are major energy storage molecules. Which statement about the complete oxidation of triglycerides to CO2 and water and the oxidation of glucose to CO, and water is true? C They are both endergonic. Glucose oxidation and triglyceride oxidation use glycolysis. Both generate the same ratio of moles of ATP per mole of fuel molecule oxidized. ATP is hydrolyzed at some point in both pathways. Both the complete oxidation of triglycerides and that of glucose use acetyl CoA as an intermediate. 11.
