What does NOT happen to pyruvate during the link reaction?
(Select all that apply)
it is oxidised
it is reduced

|
What happens to the hydrogen atoms removed from pyruvate during the link reaction?
they are used to form acetyl coenzyme A
they are used to form carbon dioxide
they are released as waste products
they are used to form reduced NAD
|
What is the primary role of coenzyme A in the link reaction?
to bind to acetate, forming acetyl coenzyme A
to reduce NAD
to remove carbon dioxide from pyruvate
to actively transport pyruvate into the mitochondria
|
What is the primary role of the coenzyme NAD in the link reaction?
to remove carbon dioxide from pyruvate
to actively transport pyruvate into the mitochondria
to bind to acetate, forming acetyl coenzyme A
to accept hydrogen atoms and become reduced
|
What happens to the carbon dioxide produced during the link reaction?
it is actively transported into the cytoplasm
it is used to form acetyl coenzyme A
it is used to reduce NAD
it diffuses out of the mitochondria as a waste product
