Question 1

What does ATP stand for?

Answer 1

Adenosine Triphosphate

Question 2

How does ATP create energy?

Answer 2

Movement occurs → last phosphate detaches → energy is released from the chemical bonds

Question 3

What does ATP become after a phosphate is released to create energy?

Answer 3

Adenosine Diphosphate
- Weak chemical bonds that cannot produce energy

Question 4

How does the body resynthesise ADP → ATP?

Answer 4

Through energy systems;
- ATP/PC
- Lactic Acid
- Aerobic

Question 5

What is the source of fuel for ATP/PC?

Answer 5

Creatine phosphate (stored readily in muscles)
- Instant reaction

Question 6

What is the source of fuel for Lactic Acid?

Answer 6

Carbohydrates → Glucose + Glycogen
- Glucose stored in blood
- Glycogen stored in muscles and liver

Question 7

What is the source of fuel for Aerobic?

Answer 7

Carbohydrates → Fats → Proteins

Question 8

What is the efficiency of ATP production for ATP/PC?

Answer 8

Very quick BUT very limited time

Question 9

What is the efficiency of ATP production for Lactic Acid?

Answer 9

Quick BUT rapid fatigue as lactic acid increases

Question 10

What is the efficiency of ATP production for Aerobic?

Answer 10

Slower BUT endless supply (until protein stores are depleted)

Question 11

What is the duration of ATP/PC?

Answer 11

1-15 seconds
- ATP → 1-2 seconds
- PC → 10-12 seconds

Question 12

What is the duration of Lactic Acid?

Answer 12

30- 180 seconds
(depending on lactic acid production)

Question 13

What is the duration of the Aerobic energy system?

Answer 13

Unlimited (until nutrients run out)

Question 14

What is the cause of fatigue for ATP/PC?

Answer 14

Limited storage of ATP and PC

Question 14

What is the cause of fatigue for Lactic Acid?

Answer 14

Accumulation of Lactic Acid

Question 14

What are the by-products of ATP/PC?

Answer 14

None/Heat

Question 15

What is the cause of fatigue for Aerobic?

Answer 15

Depletion of carbs, fats and protein stores

Question 16

What are the by-products of Lactic Acid?

Answer 16

• Lactic Acid
• Pyruvic acid (Lactic Acid being broken down)

Question 17

What are the by-products of Aerobic?

Answer 17

• Carbon Dioxide (exhaling)
• Water (sweat)

Question 18

What is the recovery rate of ATP/PC?

Answer 18

30 seconds to 2 minutes (at rest)

Question 19

What is the recovery rate of Lactic Acid?

Answer 19

20 minutes to 2 hours (increased recovery time needed due to lactic acid build up)

Question 20

What is the recovery rate of the Aerobic energy system?

Answer 20

Up to 48 hours (depending on level of depletion)
