Under certain condition your body does anaerobic reparation
sometime if you do heavy exercise you don’t have get enough oxygen going into the muscle to supply to carry aerobic respiration
so your body/muscle carries out anaerobic respiration .
And the equation for anaerobic respiration is,
GLUCOSE = LACTIC ACID + LITTLE BIT OF ENERGY
- Lactic acid is a toxic substance.
- Glucose during aerobic respiration is broken down in many steps into glucose and water during that process lots of energy is released
- if there no oxygen present then you can only get a little bit of energy produced and we make lactic acid.
- When there a build up of lactic acid which is poisonous
-the muscle become fatigued (tierd and weak) and stop contracting efficiently.
-The lactic acid has to be removed.
-The blood has to flow through muscle and take the lactic acid out. You feel it if you exercising too much.
– build up of lactic acid its poisonous so its removed by muscle.
– we have the process called oxidation
– Oxygen will come and oxidise the lactic acid which mean break it down and remove it.
– This example why someone breathes heavily after exercising
– you try supply oxygen to oxide the lactic acid and get rid of it this is called OXYGEN DEBT.
– The lactic acid can come along and be converted into carbon dioxide and water which can be removed from the both normal.
