What compound is broken down to form ATP when the muscle stores are depleted? How long can this compound maintain muscle contractions? PCr (phosphocreatine) is broken down into phosphate and creatinine to form ATP and can maintain muscle contractions for 10 seconds. Answer Key What compound is broken down to form ATP when the muscle stores are depleted? How long can this compound maintain muscle contractions? Phosphocreatine (PCr) is broken down into phosphate and creatine to form more ATP. PCr can maintain muscle contractions for approximately 10 seconds. 4.
