Hey guys, I think the answer to this E. What do u think?


13. An increase in the activity of which of the following enzymes is most likely to increase the rate of metabolism of glucose 6-phosphate through glycolysis in the liver?

A) Fructose 1,6-bisphosphatase

B) Fructose 1,6-bisphosphate aldolase (aldolase A)

C) Fructose 2,6-bisphosphatase

D) Glucokinase

E) 6-Phosphofructo-1-kinase

its C

Isn't Phospofructokinase the rate limiting emzyme in glycolysis? Fructose 2,6 bisPHOSPHATASE is a gluconeogenic enzyme, not glycolytic enzyme.

The question is asking what would increase the metabolism of glucose 6 phosphate?, well if u increase the activity of phosphfructokinase, then metabolism should increase.

These are my thoughts.
