Question

Identify which complexes in the electron transport chain are proton pumps

Answer 1

Answer:

$\huge\bold\star{\underline{\underline{\mathcal\purple{Nmste}}}}\star$

$<b>$Complexes I, III, and IV of the electron transport chain are proton pumps. As electrons move energetically downhill, the complexes capture the released energy and use it to pump H +start superscript, plus, end superscript ions from the matrix to the intermembrane space.
