Question

the diagram summarizes the electron transport chain of cellular respiration. based on the diagram, in which part of a mitochondrion do hydrogen ions build up as electrons flow though the enzyme complexes? a. the enzyme complexes b. the inner membrane c. the intermembrane space d. the matrix

Explanation:

As electrons flow through the enzyme - complexes in the electron transport chain of cellular respiration, hydrogen ions are pumped from the matrix into the intermembrane space of the mitochondrion. So, hydrogen ions build up in the intermembrane space.

Answer:

C. The intermembrane space
