Electron transport chain Flashcards
1
Q
1
A
High energy electrons move through a series of proteins and reactions.
2
Q
2
A
During the electron transport chain, the hydrogen ions are dropped off by NAD and FAD.
3
Q
3
A
They are pumped across the membrane by hydrogen pumps.
4
Q
4
A
This results in more hydrogen ions on one side of the membrane, creating a concentration gradient.
5
Q
5
A
Hydrogen ions then flow back across the membrane through a specialised protein called ATP synthase.
6
Q
6
A
ATP synthase attaches a phosphate onto an ADP molecule to make ATP, thus storing energy for later use.
7
Q
7
A
Once on the other side, the hydrogen ions then combine with oxygen to produce water, or H20.
