Phosphorylation vs hydrolysis

WebPhosphorylation requires a phosphate source of course, but also an energy source, because forming P-O bonds is not a favorable reaction on its own (the reverse of the above). So adding a lone phosphate would not be favorable, but transfering one from ATP is much better, because this simultaneously involves breaking a P-O bond in ATP, "freeing ... WebDuring a hydrolysis reaction, a molecule composed of multiple subunits is split in two: one of the new molecules gains a hydrogen atom, while the other gains a hydroxyl (-OH) group, both of which are donated by water. This is the reverse of a dehydration synthesis reaction, and it releases a monomer that can be used in building a new polymer.
