KIN 6046 – Clinicаl Exercise Physiоlоgy аnd Metаbоlism Name and explain what uses the ATP in skeletal muscle during exercise. Explain in detail the names of each enzyme and for what they use ATP, then explain how each of these enzymes are activated to start using ATP. Next, explain in detail how the ATP is provided (through which energy systems) for 30 seconds of very high workload cycling if you are pedaling as hard as you possibly can (assuming you are fully warmed up when you start). Discuss how each of the energy systems are used from 0-10 sec, 10-20 sec, and 20-30 seconds. How is each system activated?
