Electron Transport Chain Flashcards
1
Q
What is the electron transport chain?
A
A series of proteins attached to the inner mitochondrial membrane
2
Q
Where does the electron transport chain occur?
A
The cristae of the mitochondria
3
Q
What happens to the high energy electrons which were released in glycolysis and the citric acid cycle?
A
They are passed to the electron transport chain where they release energy
4
Q
What happens to the released energy?
A
It pumps hydrogen ions across the mitochondrial membrane to the inter-membrane space.
5
Q
How is ATP generated?
A
Through the return flow of hydrogen back into the matrix through ATP synthase. Generated from ADP+Pi
6
Q
What is the final hydrogen acceptor?
A
Oxygen, which combines with hydrogen to form water
