Terminal Respiration Flashcards
Where is the only site of oxidative phosphorylation in eukaryotes?
The mitochondria
Is NADH able to cross the membranes of the mitochondria?
No - but G-3-P can, passing its electrons to FADH2
Does oxidation of FADH2 in the electron transport chain generate, per mole, more or less ATP than oxidation of NADH?
Less
How many ATP molecules can ATP synthase produce for every 3 H+ it moves back into the matrix across the membrane?
One
What’s the fucking point of the whole thing?
To make ATP
Approximately how many moles of ATP are generated per mol of NADH?
2.5
Approximately how many moles of ATP are generated per mol of FADH2?
1.5
Which complex does NADH feed in electrons at?
Complex I
Which complex does FADH2 feed in electrons at?
Complex II
What is the ATP yield from the complete oxidation of one glucose molecule?
30 or 32 ATP
Electron transport is said to be __________ to ATP synthesis.
Coupled
Malignant hyperthermia is a disease caused by what?
‘Leaky’ mitochondrial membranes that uncouple electron transport and ATP synthase - can be caused by halothane
What is the name of Complex I?
NADH-Q oxidoreductase
What is the name of Complex II?
Succinate-Q reductase
What is the name of Complex III?
Q-cytochrome C oxidoreductase
