Q
How do pyruvate molecules enter the matrix of the mitochondria?
A
They are actively transported
1
Q
Why can glucose not enter the mitochondria, but pyruvate can?
A
Glucose molecules are too large to enter
2
Q
How is pyruvate oxidised?
A
By removing hydrogen
3
Q
What accepts the hydrogen in the link reaction? And what is formed?
A
NAD accepts the hydrogen to form reduced NAD
4
Q
What does pyruvate form after the removal of hydrogen?
A
An acetyl group which combines with a molecule called co-enzyme A to form a compound called acetylcoenzyme A
5
Q
What carbon containing molecule is formed from each pyruvate?
A
Carbon dioxide
