5.2.2 Link Reaction ONLY (respiration) Flashcards
1
Q
The link reaction is…
A
The conversation of pyruvate (3C) (from glycolysis) to acetyl coenzyme A (coA) (2C)
2
Q
The link reaction happens in…
A
The matrix of the mitochondria, once for each molecule of pyruvate
3
Q
First stage?
A
Decarboxylation, pyruvate loses a molecule of CO^2
4
Q
Second stage?
A
Dehydrogenation, conversion of NAD to rNAD using 2H
5
Q
Third stage?
A
Combination, addition of coenzyme A to make acetyl coA
6
Q
Yield of link reaction?
A
2 CO^2, 2 rNAD,2 acetyl coA
