MULTIPLE CHOICE QUESTION

1 min • 1 pt

What is the primary function of the creatine phosphate (CP) system?

To fuel low-intensity activities

To regenerate glycogen stores

To primarily fuel high-intensity, explosive activities

To provide oxygen to muscles

Answer explanation

The creatine phosphate (CP) system primarily fuels high-intensity, explosive activities by rapidly regenerating ATP, which is essential for short bursts of energy during intense exercise.

How long does the CP system typically last before exhaustion?

5 seconds

10 seconds

30 seconds

1 minute

Answer explanation

The CP system typically lasts for about 10 seconds before exhaustion, making it the correct choice among the options provided.

What is the lactate system primarily used for?

Low-intensity exercise

High-intensity exercise lasting longer than 10 seconds

Resting energy supply

Oxygen transport

Answer explanation

The lactate system is primarily used for high-intensity exercise lasting longer than 10 seconds, as it provides energy quickly when oxygen levels are insufficient for aerobic metabolism.

What is the primary function of the aerobic system?

Produce ATP with oxygen

Store glycogen

Release lactic acid

Break down proteins

Answer explanation

The primary function of the aerobic system is to produce ATP using oxygen. This process is essential for sustained energy during prolonged physical activity, unlike the other options which do not directly relate to the aerobic system.

MULTIPLE CHOICE QUESTION

1 min • 1 pt

Which macronutrients are primarily used in the aerobic system to produce ATP?

Proteins and vitamins

Fatty acids and carbohydrates

Minerals and water

Amino acids and glucose

Answer explanation

The aerobic system primarily uses fatty acids and carbohydrates to produce ATP. These macronutrients are oxidized in the presence of oxygen, making them essential for energy production during prolonged, moderate-intensity exercise.

Which energy system is predominantly used during a long-distance marathon?

CP system

Lactate system

Aerobic system

Anaerobic system

Answer explanation

The aerobic system is primarily used during long-distance marathons as it efficiently produces energy through oxygen, supporting sustained activity over extended periods, unlike the other systems which are more suited for shorter, high-intensity efforts.

MULTIPLE CHOICE QUESTION

1 min • 1 pt

Which energy system has the slowest speed of energy production?

CP system

Lactate system

Aerobic system

All have the same speed

Answer explanation

The aerobic system has the slowest speed of energy production compared to the CP and lactate systems, which provide energy more rapidly for short bursts of activity.
