What happens to the hydrogen atoms removed from pyruvate during the link reaction?
they are used to form acetyl coenzyme A

they are released as waste products
|
What is the primary role of coenzyme A in the link reaction?
to actively transport pyruvate into the mitochondria
to bind to acetate, forming acetyl coenzyme A

|
What is the primary role of the coenzyme NAD in the link reaction?
to accept hydrogen atoms and become reduced
to actively transport pyruvate into the mitochondria
to bind to acetate, forming acetyl coenzyme A
to remove carbon dioxide from pyruvate
|
What happens to the carbon dioxide produced during the link reaction?
it is used to form acetyl coenzyme A
it is used to reduce NAD
