Chapter 4 Flashcards
(48 cards)
Middle-dist events include
Combat sports
Boxing
Judo
Wrestling
Middle-dist events how many rounds and how long
Multiple rounds of 3-5 min duration
What is the world record for Energy and P2 cost of Middle-dist running?
1500 m pace= ~366 ml O2 per kg body mass
Or
~105 ml O2 per kg body mass/min
For a Middle-dist events Max O2 consumption at 2 min is
80-85 ml/kg/min
Anaerobic metabolism supplies how much of energy for Middle-dist events
~ 60% of energy of < 2 min event
Is there O2 in glycolysis
NO
Location of glycolysis
Cytoplasm of the cell
How much Water is retained for 1g of glycogen
2-3 gr H2O
Fraction of H and O in glucose
H:O —> 2:1
Total CHO storage in liver
~ 100 gr
Total CHO storage in muscles
~ 400-500 g in muscles
Do FA convert to CHO?
No
All dietary CHO must be converted to ——to be used by our body
Glucose
Excess protein in the diet that is unused as AA will
- Burned for energy
2. Converted to body fat
What is the end point of Glycolytic pathway ?
Pyruvate
How many carbon atoms does pyruvate have
3
Starting point of Glycolytic pathway
Store CHO in the form of glucose or glycogen
How many pyruvate in glycolytic pathway ?
2
Glucose transporter from blood to muscles
GLUT 4
What process ensures that glucose is trapped in the cell
Adding a phosphate to the glucose molecule
Overall glycolysis rxn:
Glucose + 2NAD + 2ADP + 2P → Pyruvate (3C) + 2H + 2ATP + 2H20
In anaerobic pathway pyruvate converts to
Lactate
In Aerobic pathway pyruvate attaches to ———and loses a carbon atom as Co2
Coenzyme A
When pyruvate attaches to Coenzyme A it yields
Acetyl CoA
