The polysaccharides glycogen and starch are both made up of polymers of glucose linked α-1,4 with α-1,6 branches.
In animal cells, the breakdown of endogenous glycogen is largely by phosphorolysis producing Glucose-1-P. The enzyme phosphoglucomutase converts Glucose-1-P to Glucose-6-P, which can enter glycolysis.
In contrast, the breakdown of dietary starch is by hydrolysis yielding free glucose which can then enter cells and glycolysis.
Use your understanding of glycolysis and the glycolytic template provided below to determine which of the following choices accurately describes the effect of a glucose equivalent produced by phosphorolysis versus hydrolysis on glycolysis.
