Question

Why does it take energy to pump hydrogen ions into the intermembrane

space of the mitochondria?

Answer 1

Step-by-step explanation:

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. This pumping forms an electrochemical gradient across the inner mitochondrial membrane.
