Question

Quizplus · Accepted Answer

During electron transport phosphorylation, hydrogen ions (protons) are pumped from the matrix into the intermembrane space, creating an electrochemical gradient where there is a higher concentration of protons outside the matrix. Thus, hydrogen ions accumulate in the outer compartment of the mitochondria. None of the other ions listed are directly involved in electron transport phosphorylation.
