What is the difference between a particle being hydrated versus being solvated?

#Unit 1. Molecules and their Interaction Relevant to Biology

  1. A hydrated particle is surrounded by a shell of water. A solvated molecule is surrounded by a shell of solvent molecules, not necessarily water.

  2. The terms hydrated and solvated mean exactly the same thing.

  3. A hydrated particle has reacted with hydrogen. A solvated particle is dissolved in a solvent.

  4. The word hydrated is used only when the solute is an electrolyte.

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.
