Flashcard 353: Effect of diabetes on hepatic glycolysis: _____ deficiency
- No PFK-2 activity due to lack of insulin
- No glucose trapping in liver leads to elevated blood glucose (hyperglycemia)
Answer: Glucokinase
Extra: In diabetes mellitus, insulin levels are low. Insulin normally induces the transcription of glucokinase; therefore, glucokinase is deficient in diabetes. This prevents the liver from effectively 'trapping' glucose (converting it to glucose-6-phosphate), which contributes to postprandial hyperglycemia.
