A) anaerobic glycolysis
B) creatine phosphate
C) oxidative phosphorylation
D) glycogenolysis

Question

Quizplus · Accepted Answer

Creatine phosphate is the fastest and least complex energy system used to produce ATP. It involves the transfer of a phosphate group from creatine phosphate to ADP in order to form ATP, providing a quick burst of energy that is useful for short, intense activities such as sprinting or weightlifting. Anaerobic glycolysis and glycogenolysis are also relatively fast energy systems, but they produce lactic acid as a byproduct, which can lead to fatigue and decreased performance over time. Oxidative phosphorylation is the most efficient energy system, producing large amounts of ATP, but it is slower and more complex than the other energy systems.
