Multiple Choice

Why is the ATP-CP system important for athletes in events like the high jump or gymnastics vault?

• It provides energy for long-duration activities

• It supplies quick energy for short, maximal efforts

• It helps with recovery after exercise

• It is used for endurance training

Multiple Choice

What is the main limiting factor of the ATP-CP system in muscles?

• The amount of creatine phosphate stored in the muscles

• The amount of oxygen available in the blood

• The amount of glucose stored in the liver

• The amount of lactic acid produced

Multiple Choice

A sprinter is using the ATP-CP system during a 100m dash. What must happen after the race for the sprinter to use this system again at full capacity?

• The sprinter must consume carbohydrates

• The sprinter must rest to allow CP levels to recover

• The sprinter must increase oxygen intake

• The sprinter must perform aerobic exercise

Multiple Choice

What is the initial substrate that is broken down in the anaerobic glycolysis system to produce ATP?

• Glucose

• Lactic acid

• Protein

• Fatty acids

Multiple Choice

What happens to pyruvic acid when oxygen is not available during anaerobic glycolysis?

• It is converted into lactic acid.

• It is converted into glucose.

• It is converted into ATP directly.

• It is converted into carbon dioxide.

Multiple Choice

What is the primary limiting factor of the anaerobic glycolysis system?

• Accumulation of hydrogen ions from lactic acid

• Lack of oxygen in the muscles

• Depletion of glycogen stores

• Increase in muscle temperature

Multiple Choice

How does the anaerobic glycolysis system compare to the ATP–CP system in terms of speed and ATP production?

• It is slower but produces more ATP.

• It is faster but produces less ATP.

• It is slower and produces less ATP.

• It is faster and produces more ATP.

Multiple Choice

Which of the following substances can be broken down by the aerobic system to produce ATP?

• Glucose, fatty acids, and amino acids

• Only glucose

• Only fatty acids

• Only amino acids

Multiple Choice

What is required for the aerobic system to produce ATP?

• Oxygen

• Nitrogen

• Carbon dioxide

• Lactic acid

Multiple Choice

Why is ATP produced slowly in the aerobic system?

• Because it involves many complex chemical reactions

• Because it does not require oxygen

• Because it only uses glucose as fuel

• Because it produces lactic acid

Multiple Choice

Which of the following best describes the type of exercise where the aerobic system is dominant?

• Short, explosive movements

• Prolonged exercise lasting over 60 seconds

• Activities requiring maximum strength

• Quick, high-intensity bursts

Multiple Choice

Which statement best describes the interplay of energy systems during physical activity?

• Only one energy system is active at a time.

• All three energy systems contribute at once, but the dominant system shifts based on duration of activity.

• The aerobic system is always dominant regardless of activity duration.

• The ATP-CP system is only used during rest.
