Energy Systems

Question 1

Exercise intensity —

Answer 1

Determines rate of ATP resynthesis needed

Question 2

Exercise duration –

Answer 2

Determines yield of ATP resynthesis needed

Question 3

What is ATP

Answer 3

(Adenosine Triphosphate)A+P+P+P

Compound that provides our muscles with energy

Question 4

Energy release

Answer 4

When a cell needs energy, its breaks the bond between the second and third phosphate groups, which releases a large amount of energy, forming ADP + P1

Question 5

ATP-PC System

Answer 5

• Anaerobic, doesn’t depend on oxygen
