Aerobic System

In todays lesson we learnt about the Aerobic system and the 3 different stages of it.

Stage 1
Stage 1 is called Aerobic Glycosis. Oxygen is used for this system and unlike other energy systems, this cycle is limitless. In this stage 2 molecules of ATP is reproduced. The glucose is broken down in to lactic acid and produces 2 molecules of ATP. In excercises such as sprinting the Aerobic Glycosis system can be used.

Stage 2
Stage 2 is called the Creb cycle. In the Creb cycle lactic acid from stage 1 combines together with other acids and the reaction that occurs is called the Creb cycle. 3 extra things are produced at this stage, more ATP, Carbon Dioxide and Hydrogen. During this stage 2 molecules of ATP is produced. Then the hydrogen goes to stage 3.

Stage 3
Stage 3 is called the Electron Transport Cycle. Hydrogen from stage 2 is used in this stage. At this point Hydrogen is charged positively or negatively. 1 molecule of hydrogen is made and 2 molecules of  oxygen is made, and when they combine it gives us H20 (oxygen.) During this stage 34 molecules of ATP is produced.

As a total, 38 molecules of ATP are produced through out the whole cycle. Excercises such as swimming, football, cricket, sprinting etc consists of the aerobic system.
