A)Citrate inhibits glucokinase to regulate glycolysis.
B)Glycolysis feeds acetyl-CoA,via pyruvate,to the citric acid cycle.
C)Oxaloacetate builds up when the citric acid cycle reaches saturation.
D)Glycolysis directs electrons into the electron transport chain for the purpose of ATP production.

A)C-4 proton is removed
B)creation of a carbonyl group at C-1
C)opening of the pyranose ring
D)removal of a furanose ring

A)Zn²⁺ is required for activity.
B)It is a ketose-to-aldose isomerization.
C)Transferring the carbonyl from C-1 to C-2 creates a new primary alcohol group at C-1.
D)The reaction is irreversible with a large negative ∆G.
