Question

The glycerol produced from the hydrolysis of triglycerides can enter gluconeogensis or glycolysis by phosphorylation to glycerol-3-phosphate and then oxidation to dihydroxyacetone phosphate. True or false?

Answer 1

True.

Glycerol is a byproduct of the hydrolysis of triglycerides, which are the main form of stored energy in the body. Glycerol can be converted to glucose through the process of gluconeogenesis or can be used directly for energy through the process of glycolysis.

To enter either pathway, glycerol is first phosphorylated to form glycerol-3-phosphate by the enzyme glycerol kinase. Glycerol-3-phosphate can then either be oxidized to dihydroxyacetone phosphate in the process of glycolysis or can be converted to glucose in the process of gluconeogenesis.

Therefore, the statement that glycerol produced from the hydrolysis of triglycerides can enter gluconeogenesis or glycolysis by phosphorylation to glycerol-3-phosphate and then oxidation to dihydroxyacetone phosphate is true.

Answer 2

Step-by-step explanation:

The glycerol produced from the hydrolysis of triglycerides can indeed enter both gluconeogenesis and glycolysis. It is phosphorylated to glycerol-3-phosphate and then oxidized to dihydroxyacetone phosphate, which can be further metabolized in either pathway.

So, the answer is True.
