Hey all, I am currently studying Marine Biology and have recently started an optional biochemical statistics module, in the hope that it would give me better insight into statistical analysis. Unfortunatley I didn't expenct to be handed a Thermodynamics worksheet on the first lecture! I've been working through the worksheet but I can't understand how to go about solving the question below. Any help will be much appreciated.

5) The following two transformations occur in glycolysis:

gloucose + Pi ---> gloucose-6-P + H20 ( ∆D° = +17.1 kL/mol)

PEP + H20 ---> pyruvate + Pi ( ∆D° = -55.2 kL/mol)

In glycolysis, both reactions are coupled to either ATP snthesis or hydrolysis:

ATP + H20 ---> ADP + Pi ( ∆D° = -30.5 kJ/mol)

Write down reactions for the coupled reactions and calculate their equilibrium constants at 298 K.
