16
Q

What are the products of anaerobic respiration

A

lactic acid and a little energy

17
Q

Why does anaerobic not produce as much energy

A

Energy is released throughout the process of respiration and most the process requires oxygen but the start doesn’t so aerobic respiration happens when there isnt enough oxygen to carry out the full process

18
Q

What happens when lactic acid builds up ( 2 )

A

1/ Muscles become fatigued

2/ stop contracting efficiently

19
Q

How is lactic acid removed

A

blood needs to flow through the muscle

20
Q

what is oxidation

A

The oxidization of the lactic acid

21
Q

What products are formed after lactic acid is removed

A

carbon dioxide and water

22
Q

Why is there a long period of heavy breathing after exercise

A

Repaying oxygen debt
