the link reaction and its site in the cell Flashcards
1
Q
where does the link reaction occur?
A
mitochondria
2
Q
how does pyruvate enter the mitochondria?
A
using H+ symport which is a transport protein
3
Q
what enzyme catalyzes the processes in the link reaction?
A
pyruvate dehydrogenase (a large multi-enzyme complex)
4
Q
describe the link reaction
A
- pyruvate is decarboxylated 9carboxyl group is removed) to produce carbon dioxide
- pyruvate is dehydrogenated which produces reduced NAD
- pyruvate is now Acetyl CoA (2C)
5
Q
what is produced in the link reaction?
A
- 2NADH
- 2CO2
- 2 Acetyl CoA
