This system is used for sports such as marathons where a great amount of endurance is needed.

# data[].attributes.body
Fats, carbohydrates and glucose are used as fuels for the system.

# data[].attributes.body
this production of energy(atp) occurs in the mitochondria of the muscle fibres. the mitochondria contains special enzymes that permit the breakdown of fuels such as glycogen and fatty acids through a certain interaction with oxygen which produces large amounts of energy.

# data[].attributes.body
Glucose is broken down to produce ATP.

# data[].attributes.body
IT lasts from 200-600 seconds.

# data[].attributes.body
glucose is broken down by a series of enzymes, when 2 atp are used to fuel the glycolysis which means 4 are created so the body gains two atp to use for muscular contractions

# data[].attributes.body
the sports that use the aerobic system are: walking, running, swimming, cycling, rowing and boxing etc.

# data[].attributes.body
this lasts for up to 2 hours. this may be used for marathon runners or long lasting exercise. fats and carbs are broken down to create ATP. the waste products are water and carbon dioxide.

# data[].attributes.body
The Aerobic energy system lasts as long as the exercise lasts.

# data[].attributes.body
Aerobic energy system lasts an extremely long time and is used for exercises of long duration. an example of this is a marathon
The waste products of this syetm is carbon dioxide and water
This happens in the mitochondria

1) How long does this system last and what is it used for?
= used for long distance runners or marathon runners, people undertaking exercise for a long duration at a lower intensity. anything longer than around 3 minutes
2) What is broken down during this system to produce ATP?
= carbohydates main source (gylcologyis) fats (beta oxidation)
- Glycoloysis (2ATP)
- Kreb cycle (2ATP)
- Electron transport chain (ETC) (34ATP)
3) What are the waste products of this system?
= non fatiquable
co2 and water but no waste products that will affect the activity

Where does aerobic energy production occur and what are the energy sources?
sarcoplasm
cristae of the mitochondria
matrix of the mitochondria
