Flashcards in THE AEROBIC SYSTEM Deck (8)
How is the aerobic system powered?
The aerobic system is powered by glycogen or fatty acids (stored as triglycerides).
What are the 3 stages of the aerobic system, how much ATP do they produce and where do they take place?
The 3 stages of the aerobic system are:
Stage 1- Glycolysis, 2 ATP produced, sarcoplasm.
Stage 2- Krebs cycle, 2 ATP produced, matrix of the mitochondria.
Stage 3- Electron transport train, 34 ATP produced, christae of the mitochondria.
What are the controlling enzymes involved in the aerobic system?
The controlling enzymes involved in the aerobic system are GPP, PFK and LDH.
What is the intensity of the aerobic system?
The intensity of the aerobic system is medium/low.
How much ATP is produced from the aerobic system?
Every 1 molecule of glucose= 38 molecules of ATP so the ratio 1:38.
What is the duration of the aerobic system?
The duration of the aerobic system is over 3 minutes.
What are the advantages and disadvantages of the aerobic system?
1. Gives of a tremendous energy yield.
2. Can utilise fats, which store more energy than carbohydrates.
3. The by-products are easily dealt with.
1. The process is complicated.
2. It places considerable demands on the body’s ability to deliver oxygen to the active muscles.
