ATP Breakdown

Question 1

Energy currency of the body

Answer 1

• Energy is stored in Adenosine Triphosphate (ATP)= exists in all cells + is the energy currency of the body.
• ATP is made up of atoms held together by high energy bonds:
  
  • 1 Adenosine
  • 3 Phosphates
• Separating these atoms releases energy= exothermic reaction.

Question 2

Energy production: process

Answer 2

1. Body needs energy.
2. Enzyme called ATPase is released.
3. ATPase breaks down ATP into Adenosine di-phosphate (ADP) and inorganic phosphate (Pi).
4. Energy is released through an exothermic reaction.
5. Energy is used for muscular contractions.

Question 3

Additional info

Answer 3

• Limited supply of ATP.
• Lasts for 2 seconds.
• Once it runs out ADP and Pi must be put back together (resynthesized).

Question 4

What are the 3 energy systems?

Answer 4

1. ATP-PC system
2. Anaerobic Glycolytic system
3. Aerobic system.
