ATP and Energy Systems Overview – Multiple Choice Quiz

What is the primary function of ATP in muscles?

• Provides oxygen to muscles

• Stores glycogen for energy

• Provides energy for muscle contractions

• Removes metabolic by-products

What happens when the bond between the second and third phosphate group in ATP breaks?

• ATP turns into glucose

• ATP becomes ADP and Pi

• Energy is stored for future use

• Muscle fatigue occurs

How is ATP resynthesised after it is broken down?

• Through passive diffusion

• Through three energy systems

• By recycling glucose and protein

• Through anaerobic glycolysis only

Which fuel does the ATP-CP system use?

• Glucose

• Glycogen

• Creatine phosphate (CP)

• Fatty acids

How long does the ATP-CP system typically provide energy?

• 1-3 seconds

• 6-10 seconds

• 10-60 seconds

• 1-3 minutes

What is the rate and yield of ATP production in the ATP-CP system?

• Fast rate, high yield

• Slow rate, low yield

• Fastest rate, lowest yield

• Slowest rate, highest yield

Which type of recovery is best for replenishing CP stores?

• Active recovery

• Passive recovery

• Anaerobic recovery

• Interval recovery

What is the primary fuel source for anaerobic glycolysis?

• Fats

• Creatine phosphate

• Glucose/glycogen

• Protein

What is the duration of energy provided by anaerobic glycolysis?

• 6-10 seconds

• 10-60 seconds

• 1-3 minutes

• Several hours

Which by-products are produced by anaerobic glycolysis that cause muscle fatigue?

• Carbon dioxide and water

• Creatine and phosphate

• Lactate and hydrogen ions (H⁺)

• Glucose and glycogen
