Concept explainers
(a)
Interpretation: To determine the step of glycerol
Concept introduction: Triacylglycerol mobilization is an ongoing process in which triacylglycerols that are stored in the adipose tissue are hydrolyzed. Fatty acids and glycerol are the products of triacylglycerol mobilization. The products are released into the bloodstream.
After entering the bloodstream, the glycerol travels to the kidneys or liver. The first stage of glycerol metabolism occurs in the liver or kidney. The first stage of glycerol metabolism is a two-step process. After the first stage, the remaining stages of glycerol metabolism are the same as glucose pathways. The overall equation for glycerol metabolism is as follows:
Adenosine triphosphate (ATP) is a triphosphate
(b)
Interpretation: To determine the step of glycerol metabolism in which a phosphorylation reaction occurs.

In the phosphorylation reaction, a phosphoryl group
(c)
Interpretation: To determine the step of glycerol metabolism in which dihydroxyacetone phosphate is produced.
