6 CO2
Lactate releases pH which inhibits what enzyme
Phosphofructose kinase
What is Beta-Oxidation
when you remove 2 Carbons from a fatty acid to make Acytl-CoA
You're sprinting to class and your muscles need ATP immediately. Which pathway is providing ATP the fastest?
glycolysis
Which molecule carries the MOST electrons to the electron transport chain
NADH
Why do we need O2
final electron acceptor in the etc
What is cori cycle
Its backwards glycolysis, going from muscles to the liver
Person expands 500kcals, 20% efficient. How much heat is it turned into
400kcal
If oxygen suddenly disappears, which process will stop first?
ETC
Approximately how much ATP can be generated from one glucose molecule under aerobic conditions?
30-32 ATP
What is STPD
Std Temperature Pressure Dry = Volume of gas used in indirect calorimetry
What is lactate threshold
Hypoxia and low muscle oxygen
After an hour of low intensity exercise, do you use blood glucose or muscle glycogen
blood glucose
A glucose molecule enters glycolysis. How many pyruvate molecules are produced?
2 pyruvate
What is the first carbon dioxide produced during aerobic metabolism of glucose
Pyruvate oxidation
Difference between O2 deficit and debt
Deficit = Lag in O2 uptake at the beginning of exercise
Debt = EPOC, the amount of O2 consumed in excessive rest
What are 2 ways to increase the lactate threshold
Endurance training and internal training
Jane runs 2 miles at 8min/ml and consumed 2.6L/oz per min, what is the kcal
208 kcal
How many ATP must be invested before glycolysis starts making a profit?
2 ATP
At the end of the electron transport chain, electrons are finally accepted by what
O2
What does it mean when your RER is 0.9 adn 0.8
0.9 = 2/3 carb and 1/3 fat
0.8 = 1/3 carb and 2/3 fat
4 things that cause lactate threshold
fast twitch improvement and increase glycolysis
What is the process of the Nitrogen
protein is the primary dietary source of nitrogen. Amino groups containing nitrogen are removed (deamination).
What molecule combines with acetyl-CoA to form citrate?
Oxaloacetate
Cyanide inhibits Complex IV of the electron transport chain. What would happen
Oxidative phosphorylation stops
