Energy Systems - Aerobic System (A2) Flashcards
What type of reaction is the Aerobic System process
Aerobic
Which stage does the Aerobic System follow on from?
Phosphofructokinase breaking down Glycogen into Pyruvic Acid and 2 ATP
When can you carry on the breakdown of Pyruvic Acid?
If there is sufficient oxygen
Which enzyme breaks down Pyruvic Acid and what does it produce?
Coenzyme A
Produces: Acetyl CoA
Where does Acetyl CoA move to and why does it do this?
The mitochondria as it is the site of aerobic respiration
What does Acetyl CoA combine with in the mitochondria and what does it produce?
Combines with Oxalocetic Acid to produce Citric Acid
What cycle does Citric Acid enter?
Krebs Cycle
What is citric acid split into in the Krebs Cycle?
2 ATP molecules
Hydrogen
Carbon Dioxide
What process occurs after the Krebs Cycle?
Electron Transport Chain
What is hydrogen split into (ETC)?
H+ proton
H- electron
What gas binds with the H+ molecule and what is produced?
Oxygen -> produces water
What are the names of the 2 hydrogen carriers?
NAD and FAD
How many electrons can a FAD or NAD carrier pick up?
2 electrons each (1 pair)
How much energy does FAD produce?
Enough energy for the resysnthesis of 2 ATP molecules
How much energy does NAD produce?
Enough energy for the resysnthesis of 3 ATP molecules
