ATP and Muscle Contraction Quiz

What does ATP stand for?

• Adenosine diphosphate

• Adenosine triphosphate

• Amino triphosphate

• Adenosine tetracarbon

ATP provides energy for muscle contraction by:

• Breaking down into ADP and phosphate

• Storing lactic acid

• Releasing oxygen molecules

• Absorbing carbon dioxide

How long does ATP provide immediate energy for muscle contraction?

• 10–12 seconds

• 1–2 seconds

• 30–60 seconds

• 2–3 minutes

ATP is resynthesized using which energy systems?

• Aerobic only

• ATP-PC, lactate, and aerobic

• ATP-PC and aerobic only

• Lactate and ATP-PC only

The ATP-PC system is:

• Aerobic

• Anaerobic

• Both aerobic and anaerobic

• None of the above

What are the chemical sources for ATP resynthesis in the ATP-PC system?

• Glucose and glycogen

• Oxygen and carbon dioxide

How long does it take to recover the ATP-PC system fully?

• 10–15 seconds

• 30 seconds to 2 minutes

• 5 minutes

• 24 hours

The ATP-PC system is best suited for:

• Low-intensity, long-duration activities

• High-intensity, short-duration activities

• Moderate-intensity, long-duration activities

• Continuous activities

An example of a sport relying heavily on the ATP-PC system is:

• Marathon running

• 100m sprint

• Cycling

• Swimming

The lactate system is:

• Aerobic

• Anaerobic

• Both aerobic and anaerobic

• None of the above
