To explore the consequences of coupling of atp hydrolysis under physiological conditions to a thermodynamically unfavorable biochemical reaction, consider the hypothetical transformation x-> y, for which g°’=20.0 kj/mol and 25°c. a) what is the ratio [y]/[x] at quilibrium? b) suppose x and y participate in a sequence of reactions during which atp is hydrolyzed to adp and pi. what is the overall reaction? c) what is the new [y]/[x] ratio at 25°c assuming that atp, adp, and pi are all 1 m.
