Q

What is the recovery time for the lactic acid system

A

1-2 hours

17
Q

Why is glucose broken down

A

To provide energy

18
Q

Disadvantage of lactic acid system

A

There is a build up of lactic acid

19
Q

How long does the aerobic energy system last

A

2 minutes +

20
Q

What is the recovery time for the aerobic energy system

A

24 - 48 hours

21
Q

How much yield is produced in the aerobic energy system

A

38

22
Q

What does EPOC stand for

A

Excess Post Oxygen Consumption

23
Q

What is EPOC

A

There is oxygen dept that needs repaying after aerobic exercise

24
Q

How does EPOC get repaid

A

More ATP energy is resynthesised using aerobic system to repay the dept

25
Q

What is pyruvate broken down into

A

It is broken down into acetyl CoA

26
Q

How can acetyl be produced

A

From fatty acids

27
Q

What does Acetyl pass through to produce energy

A

The krebs cycle & the Electron Transport Chain (ETC)`

28
Q

Exothermic reaction

A

Snapping of ATP
