Choose the incorrect statement

#Unit 1. Molecules and their Interaction Relevant to Biology
  1. The protein inhibitor of hexokinase IV is a nuclear binding protein that draws hexokinase IV into the nucleus when the fructose 6-phosphate concentration in liver is high and releases it to the cytosol when the glucose concentration is high.
  2. PFK-1 ATP inhibits PFK-1 by binding to an allosteric site and lowering the affinity of the enzyme for its substrate fructose 6-phosphate
  3. Hexokinase requires Mg+2 for its activity, because the true substrate of the enzyme is MgATP4- but not the MgATP2- complex.
  4. When the level of AMP increases, it promotes glycolysis by stimulating PFK-1 by inhibiting FBPase-1
