This is a bioenergetics problem, so I am going to be doing some assuming. I believe that you know by now that there are a lot of different ΔG values, and they have all these different variations and rules associated with them.
The reaction is as followed:
3-phosphoglycerate (3PG) ---> 2-phosphoglycerate (2PG)
The following equation must be used to solve the problem.
Since the reaction is at equilibrium, ΔG=0.
Plug in your values and solve for 2PG.
2PG=0.297mM or 0.30mM depending on how many significant figures that your professor/teacher wants you to report.
Now, for the second part, you only need to know the equation to use and how lnQ varies with an increase or a decrease. I am going to let Q=2/1 and 1/2=0.5 to illustrate.
lets look at the reaction in question.
1. Decreasing A and B; so from what we see with our fictional numbers, when reactants increase lnQ increases. So our equation shows us that ∆G will increase.
2. Adding a catalyst; yes this will decrease ∆G, but will it decrease the ∆G in question? No!!! However, it will cause a decrease in ∆G‡, which is equal to the difference in free energy between the transition state and the substrate (i.e., activation energy). So, ∆G will not change.
3. Coupling the reaction with ATP hydrolysis; the hydrolysis of ATP has a ∆Go'= -31.kj/mol. So, if ∆Go' decreased then ∆G decreases since you will have to add both ∆Go's together since they are coupled.
4. Decreasing C and D; I did number 1, so I will let you tackle this one.
I had problems posting, which required that I do it in two parts, which required some time.
