Anaerobic
Aerobic
Enzymes/Carbohydrates
Glycolysis

The ATP PC system provides energy for how many seconds?
around 30 seconds
100
What must be present for an energy system to be classified as an aerobic energy system? Can glycolysis be aerobic?
Oxygen. NO
100
Name the monosaccharides
Glucose, Fructose, Galactose
100
Where does Glycolysis occur?
Sarcoplasm
100
The Krebs Cycle occurs after _____ and before _____
Glycolysis/ ETC

If Usain Bolt ran the 200m in 19.19 seconds, what energy system is he using?
All of them.
200
At the end of glycolysis there are 2 ATP and pyruvate. Once oxygen is present, the pyruvate does what?
The pyruvic acid enters the mitochondria where it is converted to Acetyl Coenzyme A
200
Name the Polysaccharides and what Monosaccharides make them
Sucrose: glucose and fructose Lactose: galactose and glucose
200
How many reactions are in glycolysis?
10
200
What happens in the Krebs Cycle?
The pyruvate from Glycolysis transforms into Acetyl CoA in the presence of Oxygen.
300
If someone primarily engages in anaerobic exercise, what type of muscle fibers will they have?
Mostly Type IIx, Fast fatigue Fast Twitch

The Ironman is next weekend. Coach Eslinger is competing. He plans to take GU gels during the race to replenish his glycogen stores. Why is it important to replenish your glycogen stores?
Our bodies can only store enough glycogen (in our livers) to maintain cardiovascular exercise for around an hour. Once the glycogen is depleted, the energy source turns to protein and fat. Protein and fat take much longer to convert to energy, so they are not useful.
300
Name the Polysaccharides
cellulose and starch. *They are both formed by several glucose molecules. How they are linked is what differentiates them.
300
Explain the pyruvate lactate shuttle and it's importance
At the end of glycolysis there are pyruvate molecules. If oxygen is present, they turn in Acetyl CoA. If oxygen is not present then the pyruvate turns into lactate and stays in the anaerobic system.
300
What are the electron carriers in Krebs and what do they carry and to where do they carry it?
NAD+ and FAD carry the byproducts of the Pyruvate-->Acetyl CoA conversion to the ETC. The byproducts that are transported are Hydrogen and Carbon Dioxide
400
When someone is lifting a heavy load (85% of 1RM) for 4 sets of 3-5 reps they fatigue quickly. Why?
Lactate builds up at the end of glycolysis.
400
What produces energy faster? Aerobic or Anaerobic?
Anaerobic
400
Phosphofructokinase is the RLE for what reaction?
Glycolysis
400
If glycolysis begins with glucose molecules how many ATP are produced? What would glycolysis have to begin with for 3 ATP to be produced?
2 glycogen
400
What is the difference between the Acetyl CoA cycle, Krebs cycle, Citric Acid cycle, and the Tricarboxylic acid cycle?
nothing
500
Name all the Anaerobic energy systems from beginning to end with time limits and end products
Stored ATP: You have a few seconds of this in your body ATP PC-around 20 seconds. ATP broken down by exothermic reactions Glycolysis: 3 minutes. Pyruvate, 2 ATP
500
The ETC produces the most ATP. How many ATP are produced in the ETC?
34
500
What is LDH and why is it important?
Lactate Dehydrogenase. It catalyzes the conversion from pyruvate to lactate and back as it converts NADH to NAD+ and back.
