Much of the energy released in catabolic reactions is captured in atp for use in other reactions. when the phosphate is transferred directly from an organic molecule to adp in order to produce atp without an energized membrane, what has occurred? view available hint(s) much of the energy released in catabolic reactions is captured in atp for use in other reactions. when the phosphate is transferred directly from an organic molecule to adp in order to produce atp without an energized membrane, what has occurred? cyclic photophosphorylation oxidative phosphorylation substrate-level phosphorylation noncyclic photophosphorylation
