Multiple Choice

Free glycerol

A) is not a gluconeogenic substrate and is readily excreted in the urine.
B) is potentially gluconeogenic, and its point of entry into the gluconeogenic pathway is as pyruvate.
C) cannot support the net synthesis of glucose, because glycerol cannot be phosphorylated in vivo.
D) is potentially gluconeogenic, and its point of entry into the gluconeogenic pathway is as triose phosphate.
E) is ketogenic because it is derived from the catabolism of triacylglycerols.
