(b)

Summary Introduction

To explain: The ATP yield for the conversion of glycerol to pyruvate.

Concept introduction: Glycerol enters to the glycolytic pathway in the metabolism of fructose that occurs in liver. Fructose enters to the liver in form of fructose-1-phosphate. Fructose-1-phospahte then undergoes aldolase reaction in the presence of fructose-1-phosphate aldolase forms glyceraldehydes and dihydroxy-acetone phosphate (DHAP). Glyceraldehyde undergoes dehydrogenation process in the presence of alcohol dehydogenase forms glycerol.
