Decreases phosphofructokinase1 activity Decreases pyruvate k

Decreases phosphofructokinase-1 activity. Decreases pyruvate kinase (PK) activity Decreases hexokinase I activity Increases phosphofructokinase-1 (PFK-1) activity Increases pyruvate carboxylase activity, increasing gluconeogenesis High concentration of AMP High concentration of citrate High concentration of alanine High concentration of acetyl CoA High concentration of glucose 6-phosphate (G6P).

Solution

29. (D) High Concentration of AMP increases the phosphofructokinase-1 (PFK-1) activity.

30. (A) High Concentration of citrate decreases the phosphofructokinase-1 (PFK-1) activity. High concentrations of cytosolic citrate can inhibit phosphofructokinase.

31. (B) Pyruvate kinase has been found to be allosterically activated by FBP and allosterically inactivated by ATP and alanine

32. (E) Acetyl-CoA is an allosteric activator of pyruvate carboxylase

33. (C) G6P decreases hexokinase activity.
