(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:
Nicotinamide adenine dinucleotide is associated with the

The overall equation for glycerol metabolism is as follows:
Adenosine triphosphate (ATP) is a triphosphate
(b)
Answer to Problem 25.20EP
ADP is produced in step 1 of glycerol metabolism.
Explanation of Solution
The first stage of glycerol metabolism is a two-step process. The first step of glycerol metabolism requires energy that is provided by ATP. In this step, glycerol is converted to
The
Here, represents
Therefore, ATP is consumed in step 1 which is further converted to ADP in glycerol metabolism
(c)
Interpretation: To determine the step of glycerol metabolism in which
