Question
Researchers can manipulate the genes of a mouse so that a single gene in a single tissue either produces an inactive protein (a knockout mouse) or produces a protein that is always (constitutively) active What effects on metabolism would you predict for mice with the following genetic changes? Knockout of the FBPase-2 domain of PFK-2/FBPase-2 in the liver: Effect on glucose metabolism: Effect on glucose levels: glycogenolysis suppressed elevated blood glucose lowered glucose glycolysis suppressed glycolysis stimulated Constitutively active PFK-2 in the liver: Effect on glucose metabolism: Effect on glucose levels:Explanation / Answer
Biochemistry
Effect on metabolism predicted for mice,
Knockout of the FBPbase-2 domain of PFK-2/FBPase-2 in the liver:
Effect on glucose metabolism : Glycolysis stimulated
Effect on glucose level : lowered glucose
Constitutively active PFK-2 in the liver:
Effect on glucose metabolism : Glycolysis suppresed
Effect on glucose level : elevated blood glucose
