AAcetyl coenzyme A
BPhosphoenolpyruvate
CGlycerol-3-phosphate
DGlucose-6-phosphate
Answer & Solution
Correct answer: C. Glycerol-3-phosphate
1. Triglycerides are made of glycerol and three fatty acids, and the two parts take different routes.
2. Glycerol can be phosphorylated to glycerol-3-phosphate.
3. That compound then continues through glycolysis.
4. The fatty acid chains take the other route, becoming acetyl groups by beta oxidation.
