Glycolysis In glycolysis, ATP is formed by the transfer of a high-energy phosphate from 1,3-bisphosphoglycerate to ADR No such high-energy phosphate donor has ever been isolated in mitochondria because the techniques for isolating the phosphate donor are not refined enough None of these no such phosphate donor exists the high-energy phosphate donor is very short-lived and difficult to isolate the techniques for isolating the phosphate donor are not refined enough None of these no such phosphate donor exists the high-energy phosphate donor is very short-lived and difficult to isolate ANSWER DOWNLOAD EXAMIANS APP
