Plot of hexokinase IV (Glucokinase) is different While Hexokinases I, II, and III have similar kinetic properties. So, in given graph which of the following represents hexokinase IV and Hexokinases I, II, and III

a. i is representing Hexokinases IV

b. ii is representing Hexokinases I, II, and III

c. i is representing Hexokinases I, II, and III

d. ii is representing Hexokinases IV

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.

d. Hexokinase requires Mg+2 for its activity, because the true substrate of the enzyme is MgATP4- but not the MgATP2- complex.
