link reaction and Krebs cycle 12.2 Flashcards
1
Q
where does the link reaction take place
A
mitochondrial matrix
2
Q
what happens to pyruvate during the link reaction.
A
its oxidised to acetate by losing a CO2 molecule and 2 hydrogens.
3
Q
what happens to the acetate molecule?
A
the 2 carbon acetate molecule binds with a molecule called coenzyme A
4
Q
what is the overall equation for the link reaction.
A
pyurvate + NAD + CoA –> acetyl CoA + reduced NAD + CO2
5
Q
what is the first step of the krebs cycle?
A
Acetyl CoA binds with a 4 carbon molecule to make a 6 carbon molecule
6
Q
what happens to the coenzyme a after the first stage of the krebs cycle
A
it is recycled and reused.
