Lecture exam 2 (Aerobic metabolism) Flashcards
pyruvate enters the mitochondria of the cell for this
aerobic metabolism
aerobic demands are less than
80% max intensity
T/F: body perfers aerobic oxidative metabolism
T
This must be in sufficient concentration to have pyruvate enter the mitochondria
O2
during aerobic metabolism you use this to produce this
O2
CO2
acetic acid is an example of a
2 carbon acid
acetyl-CoA =
acetic acid + coenzyme A
484-884 rule
when we calculate ATP production we assum all pyruvate is coverted to acetyl CoA and none goes to oxaloacetate (directly)
These are the intermediate steps between glycolysis and kerbs cycle
PDH
PC
This always proceeds aerobic metabolism
anaerobic metabolism
T/F: aerobic metabolism occurs inside the sarcoplasm
F, mitochondria
Kreb’s cycle goes from here to here
citrate to citrate
2 other names for kreb’s cycle
citric acid cycle
tricarboxylic acid cycle
aerobic pathways is only used in presence of this
O2
Citrate is formed by the combination of these to intermediates by this enzyme
Acetyl-CoA
Oxaloacetate
Citrate synthase
Citrate has this many carbons
6
After citrate is reacted with aconatase this is prduced
isocitrate
isocitrate is converted to this by this enzyme
alpha-ketogluterate isocitrate dehydrogenase (IDH)
This is the rate limiting enzyme of krebs cycle
isocitrate dehydrogenase (IDH)
AKG has this many carbons
5
What happens during the IDH step other than conversion
NAD is reduced to NADH+H+
CO2 is released
This enzyme has the lowest turnover ratio in krebs cycle
IDH
Alpha-ketogluterate is converted to this by this
succinyl coenzyme A
alpha-ketogluterate dehydrogenase
succinyl coA has this man carbons
