Bioenergetics 3 Flashcards
T/F: Sprinters have really good PDH systems
F: sprinters have really good LDH systems
T/F: endurance runners have really good LDH systems
F: endurance runners have really good PDH systems
the body readily needs a pool of _____ or else _____ stalls
NAD, Glycolysis
which process makes NAD that can then be converted into NADH
Lactate Dehydrogenase
what occurs when converting pyruvic acid to lactic acid?
consuming NADH to produce NAD - maintaining redox balance
Glucose stage is cycling _____ to _____
NADH to NAD
LDH stage is cycling _____ to ______
NAD to NADH
the more pyruvic acid that is made the more _____ ______ is made
lactic acid
_____ has a negative charge compared to ______ because it gave up a _______
Lactate, lactic acid, hydrogen
PDH is an ________ enzyme
allosteric
_______ is what feeds into the krebs cycle
Acetyl CoA
humans have ________ _____ twitch
Type 2x, fast
fast twitch fibres are also called ________ fibres
anaerobic
after glycolysis 2 _______ enters the _______ (PDH rxn)
pyruvate, mitochondria
whenever CO2 is lost in a rxn ____ is being lost
carbon
when Acetyl CoA enters krebs cycle it becomes _____ then it ends the cycle as _______
citrate, oxaloacetate
Acetyl CoA + Oxaloacetate is _______
citrate synthase
what happens when “burning fat” as a result of exercise
we loose fat mass - fat leaves our body through our breath
T/F: when we exercise we have low amounts of Krebs cycle activity and all CO2 coming off leaves the body
F: when we exercise we have a lot of Krebs cycle activity and all CO2 coming off leaves the body
glycolysis can be ______ or _______ as it does not involve ____
aerobic, anaerobic, O2
beta oxidation provides acetyl CoA for ______
Krebs Cycle
_______ determine if glycolysis is aerobic or anaerobic
enzymes (LDH vs PDH)
