Answer #1

*At first protein phosphatase is activated by the insulin.

*As a result it dephosphorylates the PFK-2 complex.

*This causes PFK-2 activity

*PFK-2 increases the production of

*this product activates PFK-1 and it also activates glycolysis.

*It inhibits glyconeogenesis.

After seeing the information above we can say that option (a), (b), and (c) are incorrect.

After seeing the information above (in BOLD fonts) we can say that option (d) is correct which is "To produce F26P, which activates PFK-1 and turns on glycolysis".

Phosphofructokinase I (PFK I) catalyzes the committed step in glycolysis, which is the conversion of F 6-P to F 1,6-BP. PFK I is also allosterically inhibited by ATP. a. Since ATP is an end product of the pathway and is not the direct product of PFK-1, what term describes the inhibition of PFK I by ATP? b. Why, biochemically speaking, is ATP an appropriate inhibitor of PFK I? (Again, consider the purpose of glycolysis and the significance of the PFK...

3. The enzyme phosphofructokinase PFK (PFK1) is the main control point in glycolysis. The reverse reaction, in gluconeogenesis, is catalyzed by the enzyme fructose bisphosphatase FBPase (FBPase1). AMP and F 2’, 6’ bis phosphate are allosteric modulators of these two enzymes. Which enzyme is stimulated by these two small molecules, and which enzyme is inhibited? Why is AMP a good indicator of the ATP level in the cell? What is the value of using F2’,6’bisP as a regulator?
