Energy Sources And Systems

Question 0

Which would be the main energy system used for the 800 metres?

Answer 0

Anaerobic system

Question 1

What are the main energy sources?

Answer 1

Carbohydrates (glucose and glycogen)
Fats (triglyceride)
Protein (amino acids)
Phosphocreatin
Adenosinetriphosphate

Question 2

What is ATP splitting?

Answer 2

ATP is broken down by ATP-ase
ATP-> ADP + p(i) + energy
Lasts upto 2 seconds

Question 3

Which energy source sources the anaerobic system?

Answer 3

Carbohydrates (glucose and glycogen)

Question 4

Describe ATP-PC system

Answer 4

PC is stored in the muscles
It is broken down by creatin kinase 
PC -> P(i) + C + energy
This energy is used for the resynthesis of ATP
ADP + p(i) + energy -> ATP
ATP splitting then occurs

Question 5

What happens during Krebs cycle?

Answer 5

2 ATP are produced along with some CO2

Question 6

How is triglyceride broken down?

Answer 6

Beta oxidation

Question 7

How long does the ATP-PC system last?

Answer 7

3-11 seconds

Question 8

What is broken down into lactic acid when no oxygen is present, and in which system does this occur?

Answer 8

Pyruvate during the anaerobic system

Question 9

What is the final part of the aerobic system, and what is produced?

Answer 9

The electron transport chain, produces large amounts of ATP, water and H+ ions
