Fructose in the Diet or Fructose from Sucrose in the Diet

Fructose in the diet or fructose from sucrose in the diet can be a source of calories for fat synthesis in the liver because:

A) ketoses are fattening
B) fructose enters glycolysis after the primary regulation point, PFK-1
C) fructose provides a net of four ATP from glycolysis
D) fructose enters the branch of glycolysis that forms fat
E) glycerol (the "backbone" of triacylglycerols) comes specifically from fructose
