citric acid cycle/ox. phosphorylation Flashcards
1
Q
Each glucose generates
A
2 acetyl-coA
4 CO2
24 ATP
2
Q
pyruvate comes from
A
glucose
amino acids
3
Q
What does alpha ketoglutarate DH do
A
converts alpha ketoglutarate to succinylcholine-coA
redox rxn that makes NADH and CO2
4
Q
What does alpha ketoglutarate need to work
A
Thiamine lipolic acid coenzyme A FADH2 NADH
5
Q
how many ATPs are made from the citric cycle
A
12
6
Q
What does isocitrate DH do
A
converts isocitrate to alpha-ketoglutarate
redox rxn that makes NADH and CO2
7
Q
isocitrate DH is inhibited by
A
ATP
NADH
if inhibited, citrate will build up and go out into cytosol and inhibit PFK-1 from glycolysis except in liver where insulin activates PFK-2 and overrides inhibited PFK-1 to go forth with glycolysis
8
Q
Citrate is involved in the
A
TCA cycle
FA synthesis
