energy systems

Question 1

ATP describe its structure

Answer 1

ATP is Adenosine Tri Phosphate and provides the energy for muscular contractions. And it’s vital to carry out physical activity.

Question 2

Explain how energy is released from ATP

Answer 2

Our muscles break down the ATP to release the energy for a muscle to contract.
ATP is comprised of one adenosine and 3 phosphates that are bound together by high energy bonds. The bond connecting the final phosphate is broken and energy is release for muscles to use leaving ADP and one PI

Question 3

Explain how ATP is resynthesised (diagram is helpful)

Answer 3

Resynthesis of ATP is the process where ATP is joined back together after being broken down. The ADP and PI are joined back together, and the bond is recreated with the help of energy which comes from fuels like carbohydrates fats and proteins.

Question 4

Explain the difference between aerobic and anaerobic ATP.

Answer 4

Aerobic generates more ATP and relies on oxygen, anaerobic does not need oxygen but only creates two ATP molecules per glucose molecule.

Question 5

The characteristics of the three energy systems (table – similarities and differences)

Answer 5

SIMILARITIES
ATP is produced (ALL)
Anaerobic (ATP + ANAEROBIC)
Both share same fuel of glycogen (AEROBIC + ANAEROBIC)
DIFFERENCES
All have different rate.
All have different yield.
All have different sporting examples.

Question 6

Energy system interplay

Answer 6

All 3 energy systems are contributing ATP but there is always a major provider, we call this major provider the main contributor of ATP.

Question 7

Explain why each system loses dominance to another

Answer 7

System ATP- CP Anaerobic Aerobic
Why Pc stores will run out Due to enough o2 being consumed to work aerobically Once it becomes the major contributor
When At approx 10 sec Between 30-60 sec
It will remain this way
