the link reaction Flashcards
1
Q
how is pyruvate transported into the mitochondria?
A
via specific pyruvate-H+ symport across both membranes into matrix
2
Q
what is used in the link reaction?
A
pyruvate, coenzyme A, NAD
3
Q
describe the link reaction
A
pyruvate decarboxylated, producing CO2, and is dehydrogenated by reduction of NAD, forms acetyl group, binds with coenzyme A to form acetyl coenzyme A
4
Q
where does the link reaction take place?
A
matrix
5
Q
for each molecule of glucose, what are the products of the link reaction?
A
2 CO2, 2 reduced NAD, 2 acetyl CoA
6
Q
how many times does the link reaction occur per molecule of glucose?
A
twice
6
Q
what is the role of coenzyme A?
A
transports acetyl group from link reaction to krebs cycle
7
Q
what is not produced in the link reaction?
A
ATP
