Electron Transport Chain

Question 1

what’s Mitchell’s chemiosmotic hypothesis?

Answer 1

the potential energy associated with the
proton gradient across the inner
mitochondrial membrane provides the driving
force for the synthesis of ATP

Question 2

where does the ETC take place?

Answer 2

Occurs in or at inner mitochondrial membrane

Question 3

where does proton pumping get the energy?

Answer 3

Proton pumping driven by energy from electrons

Question 4

what’s the purpose of ETC?

Answer 4

Extract energy from high-energy electrons found in NADH & FADH2
Use energy to make ATP
