What is necessary for the immediate re-synthesis of Adenosine Triphosphate (ATP) during a long-jump event? (A) Phosphocreatine (PC) (B) Lactic acid (C) Glycogen (D) Oxygen - HSC - SSCE Personal Development and Physical Education - Question 12 - 2007 - Paper 1

To ensure the immediate re-synthesis of ATP during high-intensity activities such as a long jump, the primary energy source is phosphocreatine (PC). This compound donates a phosphate group to adenosine diphosphate (ADP) to convert it back into ATP swiftly. While lactic acid and glycogen are involved in energy production during longer duration exercise, they are not the immediate sources during explosive tasks like a long jump. Oxygen is not required for this anaerobic process either.
