Choose the correct statement
a. Hexokinases IV remains sequesters in the nucleus in case of high F-6-P and high ATP
b. Hexokinases IV remains sequesters in the cytoplasm in case of high F-6-P and high ATP
c. Hexokinase requires Mg+2 for its activity, because the true substrate of the enzyme is not ATP4- but the MgATP2- complex.
