Lactate anaerobic system

Question 1

Advantages of the Lactate anerobic system?

Answer 1

1 -ATP can be re-synthesised quite quickly due to very few chemical reactions and lasts longer than the ATP-PC system.
2 - In the presence of o2, lactic acid can be converted back into liver glycogen or used as a fuel through oxidation into CO2 and water (H2O).
3 - Can be used for a sprint finish (i.e extra burst of energy at the end of the race).

Question 2

Disadvantages of the Lactate aerobic system?

Answer 2

1 - Lactic acid is a by-product. Therefore, it stops reactions from occurring as it denatures the enzymes, prevents them from increasing the rate of chemical reactions which which take place.
2 - Only a small amount of energy can be released from glycogen under anaerobic conditions. (5% as opposed to 95% in aerobic conditions)

Question 3

1st step of Lactate aerobic systems?

Answer 3

Glycogen Is broken down into glucose which is then broken down into various enzymes which help to breakdown reactions.

Question 4

2nd step of Lactate anaerobic system?

Answer 4

1 - Glucose is broken down to synthesise ATP which results in pyruvic acid and and hydrogen ions being formed.
2 - This is due to the muscles increasing in acidity due to more hydrogen ions being formed.

Question 5

3rd step of Lactate aerobic system?

Answer 5

1 - As the system does not use 02 it can no longer synthesise ATP as there is no Oxygen to break down pyruvic acid.

Question 6

How long can the Lactate aerobic system last?

Answer 6

30 seconds - 3 minutes depending on the intensity of the activity.
