A

It is converted into a usable energy source known as adenosine triphosphate (ATP)

Q

Carbohydrates

A
  • CHO
  • broken down to glucose to be transported in the blood
  • stored in muscles and liver as glycogen
  • glycogen provides energy for ATP production under both aerobic and anaerobic conditions
  • high and low intensity exercise

Q

Fats

A
  • broken down to triglycerides
  • major source for low intensity long term activity and rest
  • can only break down under aerobic conditions
  • provides most of atp during rest
  • low intensity exercise such as jogging

Q

Protein

A
  • broken down into amino acids
  • only used in small amounts in the production of ATP
  • mainly used when carbs and fats are done
  • low intensity of very long duration exercise

Q

Phosphocreatine system

A
  • ATP-PC system
  • phosphocreatine breaks down and donates its phosphate molecule to ADP to remake ATP
  • anaerobic system (without oxygen)

Q

Lactic acid system

A
  • Produces new atp using glycogen
  • glycogen (anaerobic glycolysis) = ATP + lactic acid (stops muscles
  • anaerobic system

Q

Aerobic system

A
  • uses glycogen

- glycogen (aerobic glycolysis) =ATP + H2O + CO2 + heat

Q

Storage of ATP

A
  • muscles store it

- enough atp is stored for 2 seconds worth of activity
