The complexes within electron transport chains
A)are "circuits" for small amounts of electricity to pass through
B)contain NADH that transports electrons
C)transport H+ into the mitochondrial matrix
D)are responsible for transporting electrons and hydrogen ions
E)perform all of the above functions

Question

Quizplus · Accepted Answer

The complexes within electron transport chains are responsible for transporting electrons and hydrogen ions. They work together to pass electrons down the chain, eventually to oxygen, while also pumping hydrogen ions across the inner mitochondrial membrane, creating an electrochemical gradient.
