Aerobic energy systems
When does the oxidative system become the primary energy system?
3+ minutes
Moderate intensity aerobic exercise has what kind of ratio?
1:1
what is the enzyme known as the rate limiting factor?
PFK
Where does anaerobic glycolysis occur in the cell?
Cytoplasm
At rest what is our primary fuel source for energy?
Fats
What is another name of the Oxidative system?
The steady state system
What energy systems trigger a metabolic response?
All three (ATP-PCr, Glycolytic, and Oxidative systems)
What enzyme breaks down ATP during the ATP-PCr system?
ATPase
What is the end product of anaerobic glycolysis?
Lactate
When does protein get used as a primary fuel source?
Never
Where does NAD+ go during the oxidative system?
The ETC
What energy reserve do the muscles rely on during high-intensity exercise?
Muscle Glycogen
what enzyme for your muscle glycogen is activated during glycogenolysis?
Glycogen Phosphorylase
Do aerobic or anaerobic energy systems produce ATP at a faster rate?
Anaerobic energy system
What are the primary energy sources for aerobic and anaerobic glycolysis?
Carbohydrates (Glucose and Muscle glycogen)
During the Citric acid cycle how many FADH and CO2 are made?
1 FADH2 and 2 CO2
Explain what "cross over" means
The cross over is known as the point where one goes from primarily using fats to primarily using carbohydrates.
this enzyme helps break down phosphocreatine kinase so your muscles can quickly make ATP?
Creatine Kinase
is H+ production greater than O2 supply in anaerobic energy systems?
Yes
What is the gross amount of ATP made via Substrate Level phosphorylation during the breakdown of a glucose molecule?
6 ATP
Is the oxidative system capable of making fast ATP?
No
All of the following are slow components of EPOC except:
Elevated Body Temperature, Restoration of muscle and blood oxygen stores, Resynthesis of PCr in muscle or Post Exercise elevation of HR and breathing
Resynthesis of PCr in muscle
what enzyme breaks down fat and proteins for long term energy?
Cortisol
If Jenny ran a 400 meter race what would be the net ATP she made from M.G.?
3 ATP
What is the outcome of an athlete who has a high intensity resistance training workout but eats a low CHO diet?
Rely more on fats for fuel as CHO stores will be low when exercising. Cortisol and glucagon will increase as well during exercise
