- What is the metabolic advantage of having both hexokinase and glucokinase to phosphorylate glucose?arrow_forwardHexokinase is found in almost all animal cells, except the liver and pancreas, while glucokinase is found only in the liver and pancreas.

How does this activator activate phosphorylase (type of regulation)?arrow_forward

- Why is the isomerization of glucose-6-phosphate (G6P) to fructose-6-phosphate (F6P) an important step in glycolysis? How is the isomerization of F6P back into G6P prevented?arrow_forwardthe reaction catalyzed by glyceradehyde 3-phosphate dehydrigenase is based on NAD+ and a active site cysteine. Also another phosphate group is added. what is the reason for that? a) because one ATP is consumed b) an inorganic phosphate is activated for ATP synthesis C) NADH can be recycld and than converted back to NAD+ for glycolysis d) because one ATP is generatedarrow_forwardWhy might a general ATP-binding inhibitor be a bad idea?
