v-w -4.0
w-x +0.4
x-y -3.4
y-z +5.7
from the values of g0 in the above pathway v-w-x-y-z which compound will accumulate in the largerst amount at equilibrium?
a)v
b)w
c)x
d)y
e)z
please explain ur ans guys!

That one I know! i had it this week at the NBME!
All I know is this: The higher the dG0 the more irreversible the pathway is.
Like, if dG is Zero the system is at equilibrium. Spontaneous processes have a negative free energy change, dG is negative or less than zero.
Nonspontaneous processes have a positive free energy change, dG is positive or greater than zero. The system must take in energy from the surroundings for the process to occur.
This is an endergonic process. The reactants are forced to change by energy put into the system. Outside forces "drive" the reaction. If the system is given no additional energy the process will stop.
So, accumulation is not more reasonable to occur in spontaneous reactions? 'cos if you want to go back to the substrate you WILL need energy.
