After triacylglycerols are hydrolyzed into free fatty acids and glycerol, how is glycerol used for energy? A. It undergoes β-oxidation B. It enters the glycolysis pathway C. It enters the citric acid cycle D. It is converted to ketone bodies E. It undergoes ω-oxidation

The correct answer is B it enters glycolysis pathway.

Explanation:

Tria cylglycerol is a complex lipid which can be defined as fatty acid ester of glycerol. The hydrolytic enzyme lipase act on tri acylglycerol to form fatty acid and glycerol by hydrolyzing the ester bond present between fatty acid and glycerol.

The fatty acid enters the β oxidation pathway and the other product of tricacylglycerol hydrolysis that is glycerol is converted to glycerol - 3-phosphate by the catalyric activity of glycerol kinase. The so formed glycerol-3-phosphate is converted to glyceraldehyde-3-phosphate by alcohol dehydrogense enzyme.

The so formed glyceraldehyde-3-phosphate is an intermediate of glycolysis.
