Question

Quizplus · Accepted Answer

Phosphoarginine is used by invertebrates in a similar manner that vertebrates use phosphocreatine. Both phosphocreatine and phosphoarginine function as a reservoir of high-energy phosphate groups that can be rapidly transferred to ADP to produce ATP during periods of increased energy demand. Phosphocysteine is not commonly found in biological systems, while phosphohistidine and phosphotyrosine are generally involved in signaling pathways and not in energy storage. Phosphoaspartate is important in some metabolic pathways, but not in the same way as phosphocreatine or phosphoarginine.
