Question
Map sapling learning Phosphagens are a group of molecules that includes creatine phosphate (in vertebrates), and arginine phosphate, lombricine, and phosphoopheline (in invertebrates). These molecules have similar functions in different organisms. O CH3 N- P-O HO OH O P-O NH2 NH2 lombricine phosphate creatine phosphate NH3 NH O P-NH OH C-O-P-O phosphoopheline arginine phosphate What functions do these molecules have in common? They can be chemically converted to ATP, which is hydrolyzed to ADP to provide energy. They can accept phosphoryl groups from ATP when ATP is present in excess. They increase the strength and size of muscle tissue They can take the place of ATP in metabolic reactions when [ATP] is low in the body. They can donate phosphoryl groups to ADP to regenerate ATPExplanation / Answer
Phosphagens are the energy storage compounds, thus are also called high-energy phosphate compounds. These molecules are mostly found in muscle tissue of animals. The different types of phosphagen in different organisms supply immediate but limited energy.
The phosphagens like creatine accepts phosphate group from excess ATP and releases ADP and creatine phosphate. The phosphagens like creatine phosphate donate phosphoryl group to ADP to regenerate ATP that is hydrolyzed to supply energy to cells. This reaction is reversible and is catalyzed by creatine kinase.
