Energy Systems

Question 1

How do we get fuel for energy?

Answer 1

The body uses carbs, fat, and protein in food and from body stores for energy to fuel physical activity. They are needed regardless of the intensity of the activity

Question 2

What is ATP?

Answer 2

ATP is a molecule that provides energy for our cells to function.

Question 3

why do we need ATP?

Answer 3

We need ATP to support vital processes like muscle movement, cell division, and metabolism.

Question 4

When does ATP break down?

Answer 4

ATP breaks down when our cells require energy for activities.

Question 5

What is ATP broken down into?

Answer 5

ATP is broken down into ADP (adenosine diphosphate) and inorganic phosphate.

Question 6

At rest, short duration/ high intensity and prolonged exercise, what is the main fuel source?

Answer 6

At Rest
Main Fuel Source: Fats, as the body relies on aerobic metabolism.

Short Duration (High Intensity)
Main Fuel Source: Carbohydrates, which provide quick energy through anaerobic glycolysis.

Prolonged Exercise
Main Fuel Source: Starts with carbohydrates for energy, then shifts to fats as intensity decreases.

Question 7

What is the purpose of the energy systems? (ATP-PC)

Answer 7

Purpose: Provides immediate energy for short, intense activities like sprinting or heavy lifting.

Question 8

What is the purpose of the energy systems? (Anaerobic Glycolysis System)

Answer 8

Anaerobic Glycolysis System
Purpose: Fuels moderate to high-intensity efforts, like a 400-meter sprint.

Question 9

What is the purpose of the energy systems? (Aerobic Glycolysis System)

Answer 9

Aerobic Glycolysis System
Purpose: Supplies energy for long-duration, low to moderate-intensity activities like jogging or cycling.

Question 10

ATP-PC
- What is the main food fuel?
- How is it stored?
- Where is it stored?

Answer 10

• Carbs are the main food fuel
• It is stored in the muscles

Question 11

ATP-PC
What is the duration of the energy system? When is it dominant?

Answer 11

Lasts 2-12 seconds, and it is dominant in high-intensity, short duration activities such as sprinting

Question 12

ATP-PC
How does the system resynthesis ATP from ADP (be able explain each of the 3 processes)

Question 13

ATP-PC
Power (speed) of ATP produced
Yield (amount) of ATP produced

Question 14

ATP-PC
An advantage and disadvantage of each system

Answer 14

Advantage:
It is very quick energy

Disadvantage:
Very limited duration, only 2-12 seconds

Question 15

ATP-PC
Provide 2 sporting example for each system

Answer 15

1. 100m sprint
2. Weightlifting
3. High Jump
4. Long jump

Question 17

Anaerobic Glycolysis System
- What is the main food fuel? How is it stored? Where is it stored?

Question 18

Anaerobic Glycolysis System
What is the duration of the energy system? When is it dominant?

Answer 18

Lasts around 20-90 seconds and is most dominant in high intensity activities that last in that time frame

Question 19

Anaerobic Glycolysis System
How does the system resynthesis ATP from ADP (be able explain each of the 3 processes)

Question 20

Anaerobic Glycolysis System
Power (speed) of ATP produced
Yield (amount) of ATP produced
