ATP is a source of free energy that drives unfavorable reactions.Which of the processes are coupled to the dephosphorylation of ATP?ion transport with the concentration gradientreversible isomerization of glucose-6-phosphate to fructose-6-phosphate during glucose catabolismthe endergonic reaction forming glucose-6-phosphatemyosin action during muscle contractionde novo (from scratch) anabolism of nucleotidesOne reason that ATP is a source of energy is that the products of ATP hydrolysis have less free energy than the reactants.Why?formation of ion pairs involving ATPhydrogen bonding between free phosphate and waterresonance stabilization of free phosphateelectrostatic repulsion in ATP

The free energy changes in chemical reactions are denoted by ΔG. ∆G = ∆H − T∆S where ∆H is the…
