16
Q

how much atp is produced from on molecule of a 16 C acid

17
Q

what determines which energy is used

A

intensity and time

18
Q

most powerful system to least

A

PCR
Glycolysis
CHO oxidation
Fat oxidation

19
Q

most capacity to least

A

Fat oxidation
CHO oxidation
glycolysis
PCr

20
Q

overall chem rxn of fat oxidation

A

ffa or triglyceride to
CO2 and H2O

21
Q

do all muscles exhibit max ocidative capabiities

22
Q

what determines oxidative capacity

A

enzyme activity
electron carrier availability
fiber type composition
endurance trainin g
mitochondira density
capillary density
oxygen availabiltiy vs o2 needed

23
Q

what is the biggest thing that effects oxidative capacity

A

ENZYME activityyyy

24
Q

are type 1 fibers have a greater or lesser oxidative capacity

25
what does type 1 fibers have more of
mitochondira and higher oxidative enzyme concentrations
26
what are type 2 fivers better for
glycolytic energy production
27
what does endurance traiing do to type 2 fibers
enhances oxidative capacity develops more or larger mitochondira and develops more oxidative enzymes
28
is o2 storage limited
yes
29
what does the o2 levels entering and leaving the lungs tell us
an estimate of o2 use in muscles
30
atpe demand of muscle increases with intensity , so in response what happens
increase in rate of oxidative atp production increase in 02 intake at lungs increase in o2 delivery by the heart and vessels
