Role of creatine phosphate in muscle ?: (A) Helps in gluconeogenesis, (B) Provides instant energy, (C) Involved in action-contraction coupling, (D) Helps in stretch reflex
Answer is B. Ans. is 'b' i.e., Provides instant energy In muscles, creatine phosphate occurs as a reservoir of high-energy phosphate groups.It provides a quick source of energy for muscle fibres to contract when they need an initial burst of energy.Creatine phosphate helps generation of ATP in exercising muscles by substrate level phosporylation.
