Based �on� free� energies� of �hydrolysis�given� below,� for� each �of� the� following�reactions:�

Question

i)�Determine� the� overall� ∆G� of �the�reaction�

ii)�State� whether� it �is �favorable�(spontaneous)�as� written��

∆Ghydrolysis

Phosphocreatine� � � '43.1�kJ/mol�
Glycerolphosphate� � � '9.7�kJ/mol�
Phosphoenolpyruvate� � '61.9�kJ/mol�
Glucose'6'phosphate� � '12.5�kJ/mol�

a. �ATP� + �creatine� <->�Phosphocreatine� + �ADP�

b.� ATP �+� glycerol� <-> glycerolphosphate� +�ADP�

c.�ADP �+ �Phosphoenopyruvate� <-> pyruvate�+ �ATP�

d.�pyruvate �+� glucose'6'phosphate� <-> glucose� +� phosphoenopyruvate

The arrows are supposed to be separate arrows, going in opposite directions. I'm really stuck and I don't understand this question. Please help soon.
