quiz 3 Flashcards
atp is high at
at rest
atp is low
during high intensity exericse
PCr system
uses Pcr to replenish ATP
No O2 -substate level phosphorlyation
Glycolytic pathway
uses glucose to produce ATP and pyruvate
-in sacroplasm
no O2 used - substrate level phosphorlation
Oxidative pathway
in mitochondria
-O2 used a final electron (H) acceptor
- located within mitochondria
-includes krebs cycle and ETC and beta ox
ATP Pcr
Very fast and very limited
-no O2
-substrate level
-creatine kinase
-resupplies ATP during work
-most active at the beginning of work
glycolysis
-sarcoplasm
-no O2
-substrate level synthesis of ATP
-catabolizes glucose to pyruvate and or lactate
substrate for glycolysis
glucose from blood or muscle glycogen
substrate for gluconeogensis
glycerol
AA
pyruvate or lactate
gluconeogensis
making of new glucose in the liver
incomplete oxidation of glucose
end product pyruvate converted to lactate
complete oxidation of glucose
end product = pyruvate to the mitochondria
ETC is the only one that used what RE
NADH
what does PDH do
turns pyruvate into acetyl COA
links glycolysis to krebs
krebs produced RE to ETC
NADH and FADH2
