10 Questions
Where is the location of the Electron Transport Chain (ETC)?
Inner membrane space of the mitochondria
What is the actual driving force used to power ATP synthase in the Electron Transport Chain?
Proton motive force
What is the function of ATP synthase in the Electron Transport Chain?
ATP synthase’s spinning generates energy which combines ADP and Pi, producing ATP
How many ATPs are produced by NADH in the Electron Transport Chain?
3
What is the primary driving force used to power ATP synthase in the Electron Transport Chain?
Electrochemical gradient caused by the accumulation of protons
Why does FADH2 produce 1 less ATP than NADH in the Electron Transport Chain?
The glycerol-3-phosphate shuttle system carries the electrons to FADH2, whereas the malate-aspartate system carries them to NADH
Where does the Electron Transport Chain (ETC) take place?
Inner membrane space of the mitochondria
How many ATPs are produced by NADH in the Electron Transport Chain?
3
What is the function of ATP synthase in the Electron Transport Chain?
Generating ATP by combining ADP and Pi
Why does FADH2 produce 1 less ATP than NADH in the Electron Transport Chain?
Electrons are carried to FADH2 by the glycerol-3-phosphate shuttle system
Study Notes
Electron Transport Chain (ETC) Location
- The Electron Transport Chain (ETC) takes place in the mitochondrial inner membrane.
Driving Force of ATP Synthase
- The primary driving force used to power ATP synthase in the Electron Transport Chain is the proton gradient.
Function of ATP Synthase
- The function of ATP synthase in the Electron Transport Chain is to generate ATP from ADP and Pi.
ATP Production by NADH and FADH2
- NADH produces 2.5-3 ATP in the Electron Transport Chain.
- FADH2 produces 1.5-2 ATP in the Electron Transport Chain, 1 less than NADH, due to the difference in the energy released during the electron transport process.
Test your knowledge of the electron transport chain with this quiz. Explore the actual driving force used to power ATP synthase and the location of the ETC. Challenge yourself to understand how electrons flow through the ETC to produce ATP.
