For the reaction ATP + H2O ⇔ ADP + phosphate, ΔG° = -30.5 kJ/mol. Very high concentrations of ADP and phosphate (such that Q>>K) would likely have which of the following effects (explain your thinking): a. ΔG would be less negative than ΔG°, because conditions would disfavor the formation of more ADP b. ΔG would be more negative than ΔG°, because conditions would favor the formation of more ADP c. ΔG° and ΔG are unrelated in this case, because conditions...
